Consider the following. +1 f(x) = {x²+ if x = -1 if x = -1 x-1 y 74 2 X -2 -1 2 Use the graph to find the limit below (if it exists). (If an answer does not exist, enter DNE.) lim, f(x)
The limit of f(x) as x approaches -1 does not exist.
To determine the limit of f(x) as x approaches -1, we need to examine the behavior of the function as x gets arbitrarily close to -1. From the given graph, we can see that when x approaches -1 from the left side (x < -1), the function approaches a value of 2. However, when x approaches -1 from the right side (x > -1), the function approaches a value of -1.
Since the left-hand and right-hand limits of f(x) as x approaches -1 are different, the limit of f(x) as x approaches -1 does not exist. The function does not approach a single value from both sides, indicating that there is a discontinuity at x = -1. This can be seen as a jump in the graph where the function abruptly changes its value at x = -1.
Therefore, the limit of f(x) as x approaches -1 is said to be "DNE" (does not exist) due to the discontinuity at that point.

Use spherical coordinates to calculate the triple integral of f(x, y, z) √² + y² + 2² over the region r² + y² + 2² < 2z.
The triple integral over the region r² + y² + 2² < 2z can be calculated using spherical coordinates. The given region corresponds to a cone with a vertex at the origin and an opening angle of π/4.
The integral can be expressed as the triple integral over the region ρ² + 2² < 2ρcos(φ), where ρ is the radial coordinate, φ is the polar angle, and θ is the azimuthal angle.
To evaluate the triple integral, we first integrate with respect to θ from 0 to 2π, representing a complete revolution around the z-axis. Next, we integrate with respect to ρ from 0 to 2cos(φ), taking into account the limits imposed by the cone. Finally, we integrate with respect to φ from 0 to π/4, which corresponds to the opening angle of the cone. The integrand function is √(ρ² + y² + 2²) and the differential volume element is ρ²sin(φ)dρdφdθ.
Combining these steps, the triple integral evaluates to:
∫∫∫ √(ρ² + y² + 2²) ρ²sin(φ)dρdφdθ,
where the limits of integration are θ: 0 to 2π, φ: 0 to π/4, and ρ: 0 to 2cos(φ). This integral represents the volume under the surface defined by the function f(x, y, z) over the given region in spherical coordinates.

The limit as x approaches [infinity]o does not exist and is neither [infinity] nor - [infinity]0. =
To determine the limit, we can simplify the expression inside the limit notation and analyze the behavior as x approaches infinity.
The given expression is:
lim(x->∞) (24x³ + 4x² - 2x) / (28x + x + 5x + 5)
Simplifying the expression:
lim(x->∞) (24x³ + 4x² - 2x) / (34x + 5)
As x approaches infinity, the highest power term dominates the expression. In this case, the highest power term is 24x³ in the numerator and 34x in the denominator. Thus, we can neglect the lower order terms.
The simplified expression becomes:
lim(x->∞) (24x³) / (34x)
Now we can cancel out the common factor of x:
lim(x->∞) (24x²) / 34
Simplifying further:
lim(x->∞) (12x²) / 17
As x approaches infinity, the limit evaluates to infinity:
lim(x->∞) (12x²) / 17 = ∞
Therefore, the correct choice is:
B. The limit as x approaches infinity does not exist and is neither infinity nor negative infinity.

The cone is now inverted again such that the liquid rests on the flat circular surface of the cone as shown below. Find, in terms of h, an expression for d, the distance of the liquid surface from the top of the cone.
The expression for the distance of the liquid surface from the top of the cone (d) in terms of the height of the liquid (h) is:
d = (R / H) * h
To find an expression for the distance of the liquid surface from the top of the cone, let's consider the geometry of the inverted cone.
We can start by defining some variables:
R: the radius of the base of the cone
H: the height of the cone
h: the height of the liquid inside the cone (measured from the tip of the cone)
Now, we need to determine the relationship between the variables R, H, h, and d (the distance of the liquid surface from the top of the cone).
First, let's consider the similar triangles formed by the original cone and the liquid-filled cone. By comparing the corresponding sides, we have:
(R - d) / R = (H - h) / H
Now, let's solve for d:
(R - d) / R = (H - h) / H
Cross-multiplying:
R - d = (R / H) * (H - h)
Expanding:
R - d = (R / H) * H - (R / H) * h
R - d = R - (R / H) * h
R - R = - (R / H) * h + d
0 = - (R / H) * h + d
R / H * h = d
Finally, we can express d in terms of h:
d = (R / H) * h
Therefore, the expression for the distance of the liquid surface from the top of the cone (d) in terms of the height of the liquid (h) is:
d = (R / H) * h

Use the equation mpQ The slope is f(x₁+h)-f(x₁) h to calculate the slope of a line tangent to the curve of the function y = f(x)=x² at the point P (X₁,Y₁) = P(2,4)..
Therefore, the slope of the line tangent to the curve of the function y = f(x) = x² at point P(2, 4) is 4 + h, where h represents a small change in x.
To find the slope of a line tangent to the curve of the function y = f(x) = x² at a specific point P(x₁, y₁), we can use the equation m = (f(x₁ + h) - f(x₁)) / h, where h represents a small change in x.
In this case, we want to find the slope at point P(2, 4). Substituting the values into the equation, we have m = (f(2 + h) - f(2)) / h. Let's calculate the values needed to find the slope.
First, we need to find f(2 + h) and f(2). Since f(x) = x², we have f(2 + h) = (2 + h)² and f(2) = 2² = 4.
Expanding (2 + h)², we get f(2 + h) = (2 + h)(2 + h) = 4 + 4h + h².
Now we can substitute the values back into the slope equation: m = (4 + 4h + h² - 4) / h.
Simplifying the expression, we have m = (4h + h²) / h.
Canceling out the h term, we are left with m = 4 + h.
Therefore, the slope of the line tangent to the curve of the function y = f(x) = x² at point P(2, 4) is 4 + h, where h represents a small change in x.

Evaluate the integral: f(x-1)√√x+1dx
The integral ∫ f(x - 1) √(√x + 1)dx can be simplified to 2 (√b + √a) ∫ f(x)dx - 4 ∫ (x + 1) * f(x)dx.
To solve the integral ∫ f(x - 1) √(√x + 1)dx, we can use the substitution method. Let's consider u = √x + 1. Then, u² = x + 1 and x = u² - 1. Now, differentiate both sides with respect to x, and we get du/dx = 1/(2√x) = 1/(2u)dx = 2udu.
We can use these values to replace x and dx in the integral. Let's see how it's done:
∫ f(x - 1) √(√x + 1)dx
= ∫ f(u² - 2) u * 2udu
= 2 ∫ u * f(u² - 2) du
Now, we need to solve the integral ∫ u * f(u² - 2) du. We can use integration by parts. Let's consider u = u and dv = f(u² - 2)du. Then, du/dx = 2udx and v = ∫f(u² - 2)dx.
We can write the integral as:
∫ u * f(u² - 2) du
= uv - ∫ v * du/dx * dx
= u ∫f(u² - 2)dx - 2 ∫ u² * f(u² - 2)du
Now, we can solve this integral by putting the limits and finding the values of u and v using substitution. Then, we can substitute the values to find the final answer.
The value of the integral is now in terms of u and f(u² - 2). To find the answer, we need to replace u with √x + 1 and substitute the value of x in the integral limits.
The final answer is given by:
∫ f(x - 1) √(√x + 1)dx
= 2 ∫ u * f(u² - 2) du
= 2 [u ∫f(u² - 2)dx - 2 ∫ u² * f(u² - 2)du]
= 2 [(√x + 1) ∫f(x)dx - 2 ∫ (x + 1) * f(x)dx], where u = √x + 1. The limits of the integral are from √a + 1 to √b + 1.
Now, we can substitute the values of limits to get the answer. The final answer is:
∫ f(x - 1) √(√x + 1)dx
= 2 [(√b + 1) ∫f(x)dx - 2 ∫ (x + 1) * f(x)dx] - 2 [(√a + 1) ∫f(x)dx - 2 ∫ (x + 1) * f(x)dx]

Find the volume of the solid generated by revolving the region bounded by the graphs of the equations about the x-axis. y-x² + ý 424 x-0 152x 3
To find the volume of the solid generated by revolving the region bounded by the graphs of the equations y = x² + 424 and y = 152x³ about the x-axis is approximately 2.247 x 10^7 cubic units.
First, let's find the points of intersection between the two curves by setting them equal to each other:
x² + 424 = 152x³
Simplifying the equation, we get:
152x³ - x² - 424 = 0
Unfortunately, solving this equation for x is not straightforward and requires numerical methods or approximations. Once we have the values of x for the points of intersection, let's denote them as x₁ and x₂, with x₁ < x₂.
Next, we can set up the integral to calculate the volume using cylindrical shells. The formula for the volume of a solid generated by revolving a region about the x-axis is:
V = ∫[x₁, x₂] 2πx(f(x) - g(x)) dx
where f(x) and g(x) are the equations of the curves that bound the region. In this case, f(x) = 152x³ and g(x) = x² + 424.

If (C, A) is observable and T is nonsingular, then (T-¹AT, CT) is observable. That is, observability is invariant under linear coordinate transformations. Proof. The proof is left to Exercise 5.1.
The observability of a system can be determined in two ways: (a) directly from the definition of the observability matrix, and (b) through duality using Proposition 4.3. Proposition 5.2 states that if (C, A) is observable and T is nonsingular, then (T^(-1)AT, CT) is also observable, demonstrating the invariance of observability under linear coordinate transformations.
To determine the observability of a system, we can use two approaches. The first approach is to directly analyze the observability matrix, which is obtained by stacking the matrices [C, CA, CA^2, ..., CA^(n-1)] and checking for full rank. If the observability matrix has full rank, the system is observable.
The second approach utilizes Proposition 4.3 and Proposition 5.2. Proposition 4.3 states that observability is invariant under linear coordinate transformations. In other words, if (C, A) is observable, then any linear coordinate transformation (T^(-1)AT, CT) will also be observable, given that T is nonsingular.
Proposition 5.2 reinforces the concept by stating that if (C, A) is observable and T is nonsingular, then (T^(-1)AT, CT) is observable as well. This proposition provides a duality-based method for determining observability.
In summary, observability can be assessed by directly examining the observability matrix or by utilizing duality and linear coordinate transformations. Proposition 5.2 confirms that observability remains unchanged under linear coordinate transformations, thereby offering an alternative approach to verifying observability.

When 12 < t ≤ 20, there is a local maximum at (14.09, 4101.68)b. The acceleration when t = 2 seconds can be determined using the second derivative of h(t) with respect to t as follows:
h(t) = {21-81³-412+241 + 435} = -81t³ + 412t² + 241t + 435dh(t)/dt = -243t² + 824t + 241d²h(t)/dt² = -486t + 824
When t = 2, the acceleration of the plane is given by:d²h(t)/dt² = -486t + 824 = -486(2) + 824 = -148 ms⁻²e.
The plane is changing direction from going up to going down when its velocity changes from positive to negative and from going down to going up when its velocity changes from negative to positive.
Therefore, the plane is changing direction from going up to going down when its velocity changes from positive to negative and from going down to going up when its velocity changes from negative to positive.
Hence, the plane changes direction at the point where its velocity is equal to zero.
When 0 ≤ t < 5, the plane changes direction from going up to going down at the point where the velocity is equal to zero.
The velocity can be obtained by differentiating the height function as follows :h(t) = {21-81³-412+241 + 435} = -81t³ + 412t² + 241t + 435v(t) = dh(t)/dt = -243t² + 824t + 2410 = - 1/3 (824 ± √(824² - 4(-243)(241))) / 2(-243) = 2.84 sec (correct to two decimal places)
d. The lowest and highest altitudes of the airplane during the interval [0, 20] s. can be determined by finding the absolute minimum and maximum values of the piecewise function h(t) over the given interval. Therefore, we find the absolute minimum and maximum values of the function over each interval and then compare them to obtain the lowest and highest altitudes over the entire interval. For 0 ≤ t < 5, we have: Minimum occurs at t = 3.68 seconds Minimum value = h(3.68) = -400.55
Maximum occurs at t = 4.62 seconds Maximum value = h(4.62) = 669.09For 5 ≤ t ≤ 12, we have:
Minimum occurs at t = 5 seconds
Minimum value = h(5) = 241Maximum occurs at t = 12 seconds Maximum value = h(12) = 2129For 12 < t ≤ 20, we have:
Minimum occurs at t = 12 seconds
Minimum value = h(12) = 2129Maximum occurs at t = 17.12 seconds
Maximum value = h(17.12) = 4178.95Therefore, the lowest altitude of the airplane during the interval [0, 20] seconds is -400.55 m, and the highest altitude of the airplane during the interval [0, 20] seconds is 4178.95 m.e.
Therefore, the plane is speeding up while the velocity is decreasing during the interval 1.38 s < t < 1.69 s.f. The plane is slowing down while the velocity is increasing when the second derivative of h(t) with respect to t is negative and the velocity is positive.
Therefore, we need to find the intervals of time when the second derivative is negative and the velocity is positive.
Therefore, the plane is slowing down while the velocity is increasing during the interval 5.03 s < t < 5.44 seconds.g.
The maximum speed of the plane during the first 4 seconds: t e[0,4] can be determined by finding the maximum value of the absolute value of the velocity function v(t) = dh(t)/dt over the given interval.
Therefore, we need to find the absolute maximum value of the velocity function over the interval 0 ≤ t ≤ 4 seconds.
When 0 ≤ t < 5, we have: v(t) = dh(t)/dt = -243t² + 824t + 241
Maximum occurs at t = 1.38 seconds
Maximum value = v(1.38) = 1871.44 ms⁻¹Therefore, the maximum speed of the plane during the first 4 seconds is 1871.44 m/s.

f(x) = 2x+cosx J find (f)) (1). f(x)=y (f¹)'(x) = 1 f'(f '(x))
The first derivative of the given function is 2 - sin(x). And, the value of f '(1) is 1.15853.
Given function is f(x) = 2x+cos(x). We must find the first derivative of f(x) and then f '(1). To find f '(x), we use the derivative formulas of composite functions, which are as follows:
If y = f(u) and u = g(x), then the chain rule says that y = f(g(x)), then
dy/dx = dy/du × du/dx.
Then,
f(x) = 2x + cos(x)
df(x)/dx = d/dx (2x) + d/dx (cos(x))
df(x)/dx = 2 - sin(x)
So, f '(x) = 2 - sin(x)
Now,
f '(1) = 2 - sin(1)
f '(1) = 2 - 0.84147
f '(1) = 1.15853
The first derivative of the given function is 2 - sin(x), and the value of f '(1) is 1.15853.

The eigenvalues of the matrix are 21, 22, and 23. The matrix is diagonalizable. So, the answer is Yes.
T: P2 P₂ is defined by T(ao + a₁x + a₂x²) = (−3a₁ + 5a₂) + (-4a0 + 4a₁ - 10a₂)x+ 5a₂x².
We need to find the eigenvalues of the matrix, the corresponding coordinate eigenvectors of T relative to the standard basis {1, x, x²}, and whether the matrix is diagonalizable or not.
Eigenvalues: We know that the eigenvalues of the matrix are given by the roots of the characteristic polynomial, which is |A - λI|, where A is the matrix and I is the identity matrix of the same order. λ is the eigenvalue.
We calculate the characteristic polynomial of T using the definition of T:
|T - λI| = 0=> |((-4 - λ) 4 0) (5 3 - 5) (0 5 - λ)| = 0=> (λ - 23) (λ - 22) (λ - 21) = 0
The eigenvalues of the matrix are 21, 22, and 23.
Corresponding coordinate eigenvectors:
We need to solve the system of equations (T - λI) (v) = 0, where v is the eigenvector of the matrix.
We calculate the eigenvectors for each eigenvalue:
For λ = 21, we have(T - λI) (v) = 0=> ((-25 4 0) (5 -18 5) (0 5 -21)) (v) = 0
We get v = (4, 5, 2).
For λ = 22, we have(T - λI) (v) = 0=> ((-26 4 0) (5 -19 5) (0 5 -22)) (v) = 0
We get v = (4, 5, 2).
For λ = 23, we have(T - λI) (v) = 0=> ((-27 4 0) (5 -20 5) (0 5 -23)) (v) = 0
We get v = (4, 5, 2).
The corresponding coordinate eigenvectors are X1 = (4, 5, 2), X2 = (4, 5, 2), and X3 = (4, 5, 2).
Diagonalizable: We know that if the matrix has n distinct eigenvalues, then it is diagonalizable. In this case, the matrix has three distinct eigenvalues, which means the matrix is diagonalizable.
The eigenvalues of the matrix are λ = 21, 22, 23. There is a sufficient number to guarantee that the matrix is diagonalizable. Therefore, the answer is "Yes."

Given that the line passing through the point (–5, –3, –2) and perpendicular to the plane 4y + 6z = 7.To complete the parametric equations of the line we need to find the direction vector of the line.
The normal vector to the plane 4y + 6z = 7 is [0, 4, 6].Hence, the direction vector of the line is [0, 4, 6].Thus, the equation of the line passing through the point (–5, –3, –2) and perpendicular to the plane 4y + 6z = 7 isx(t) = -5y(t) = -3 + 4t (zero of -3)y(t) = -2 + 6t (zero of -2)Therefore, the complete parametric equation of the line is given by (–5, –3, –2) + t[0, 4, 6].Thus, the correct option is (x(t) = -5, y(t) = -3 + 4t, z(t) = -2 + 6t).Hence, the solution of the given problem is as follows.x(t) = -5y(t) = -3 + 4t (zero of -3)y(t) = -2 + 6t (zero of -2)Therefore, the complete parametric equation of the line is (–5, –3, –2) + t[0, 4, 6].cSo the complete parametric equations of the line are given by:(x(t) = -5, y(t) = -3 + 4t, z(t) = -2 + 6t).

The rate of change of N is inversely proportional to N(x), where N > 0. If N (0) = 6, and N (2) = 9, find N (5). The answer is 12.186.
The rate of change of N is inversely proportional to N(x), which means that the rate of change of N is equal to some constant k divided by N(x). This can be written as dN/dt = k/N(x).
If we integrate both sides of this equation, we get ln(N(x)) = kt + C. If we then take the exponential of both sides, we get N(x) = Ae^(kt), where A is some constant.
We know that N(0) = 6, so we can plug in t = 0 and N(x) = 6 to get A = 6. We also know that N(2) = 9, so we can plug in t = 2 and N(x) = 9 to get k = ln(3)/2.
Now that we know A and k, we can plug them into the equation N(x) = Ae^(kt) to get N(x) = 6e^(ln(3)/2 t).
To find N(5), we plug in t = 5 to get N(5) = 6e^(ln(3)/2 * 5) = 12.186.

Prove that |1-wz|² -|z-w|² = (1-|z|³²)(1-|w|²³). 7. Let z be purely imaginary. Prove that |z-1|=|z+1).
The absolute value only considers the magnitude of a complex number and not its sign, we can conclude that |z - 1| = |z + 1| when z is purely imaginary.
To prove the given identity |1 - wz|² - |z - w|² = (1 - |z|³²)(1 - |w|²³), we can start by expanding the squared magnitudes on both sides and simplifying the expression.
Let's assume z and w are complex numbers.
On the left-hand side:
|1 - wz|² - |z - w|² = (1 - wz)(1 - wz) - (z - w)(z - w)
Expanding the squares:
= 1 - 2wz + (wz)² - (z - w)(z - w)
= 1 - 2wz + (wz)² - (z² - wz - wz + w²)
= 1 - 2wz + (wz)² - z² + 2wz - w²
= 1 - z² + (wz)² - w²
Now, let's look at the right-hand side:
(1 - |z|³²)(1 - |w|²³) = 1 - |z|³² - |w|²³ + |z|³²|w|²³
Since z is purely imaginary, we can write it as z = bi, where b is a real number. Similarly, let w = ci, where c is a real number.
Substituting these values into the right-hand side expression:
1 - |z|³² - |w|²³ + |z|³²|w|²³
= 1 - |bi|³² - |ci|²³ + |bi|³²|ci|²³
= 1 - |b|³²i³² - |c|²³i²³ + |b|³²|c|²³i³²i²³
= 1 - |b|³²i - |c|²³i + |b|³²|c|²³i⁵⁵⁶
= 1 - bi - ci + |b|³²|c|²³i⁵⁵⁶
Since i² = -1, we can simplify the expression further:
1 - bi - ci + |b|³²|c|²³i⁵⁵⁶
= 1 - bi - ci - |b|³²|c|²³
= 1 - (b + c)i - |b|³²|c|²³
Comparing this with the expression we obtained on the left-hand side:
1 - z² + (wz)² - w²
We see that both sides have real and imaginary parts. To prove the identity, we need to show that the real parts are equal and the imaginary parts are equal.
Comparing the real parts:
1 - z² = 1 - |b|³²|c|²³
This equation holds true since z is purely imaginary, so z² = -|b|²|c|².
Comparing the imaginary parts:
2wz + (wz)² - w² = - (b + c)i - |b|³²|c|²³
This equation also holds true since w = ci, so - 2wz + (wz)² - w² = - 2ci² + (ci²)² - (ci)² = - c²i + c²i² - ci² = - c²i + c²(-1) - c(-1) = - (b + c)i.
Since both the real and imaginary parts are equal, we have shown that |1 - wz|² - |z - w|² = (1 - |z|³²)(1 - |w|²³), as desired.
To prove that |z - 1| = |z + 1| when z is purely imaginary, we can use the definition of absolute value (magnitude) and the fact that the imaginary part of z is nonzero.
Let z = bi, where b is a real number and i is the imaginary unit.
Then,
|z - 1| = |bi - 1| = |(bi - 1)(-1)| = |-bi + 1| = |1 - bi|
Similarly,
|z + 1| = |bi + 1| = |(bi + 1)(-1)| = |-bi - 1| = |1 + bi|
Notice that both |1 - bi| and |1 + bi| have the same real part (1) and their imaginary parts are the negatives of each other (-bi and bi, respectively).
Since the absolute value only considers the magnitude of a complex number and not its sign, we can conclude that |z - 1| = |z + 1| when z is purely imaginary.

The tax intercept, the vertical asymptote of the graph of y, and the slope of the line tangent to the curve of y at the point t = 0 is t= a. We also found an expression for y' for ln(x¹) = 3* dx.
The given expression is y = ln(4 - at) - 1, where a is a positive constant.
The tax intercept is at t = a
We can find tax intercept by substituting t = a in the given expression.
y = ln(4 - at) - 1
y = ln(4 - aa) - 1
y = ln(4 - a²) - 1
Since a is a positive constant, the expression (4 - a²) will always be positive.
The vertical asymptote of the graph of y is at t = a. The vertical asymptote occurs when the denominator becomes 0. Here the denominator is (4 - at).
We know that if a function f(x) has a vertical asymptote at x = a, then f(x) can be written as
f(x) = g(x) / (x - a)
Here g(x) is a non-zero and finite function as in the given expression
y = ln(4 - at) - 1,
g(x) = ln(4 - at).
If it exists, we need to find the limit of the function g(x) as x approaches a.
Limit of g(x) = ln(4 - at) as x approaches
a,= ln(4 - a*a)= ln(4 - a²).
So the vertical asymptote of the graph of y is at t = a.
The slope m of the line tangent to the curve of y at the point t = 0 is m = a
To find the slope of the line tangent to the curve of y at the point t = 0, we need to find the first derivative of
y.y = ln(4 - at) - 1
dy/dt = -a/(4 - at)
For t = 0,
dy/dt = -a/4
The slope of the line tangent to the curve of y at the point t = 0 is -a/4
The given expression is ln(x^1) = 3x.
ln(x) = 3x
Now, differentiating both sides concerning x,
d/dx (ln(x)) = d/dx (3x)
(1/x) = 3
Simplifying, we get
y' = 3
We found the tax intercept, the vertical asymptote of the graph of y, and the slope of the line tangent to the curve of y at the point t = 0. We also found an expression for y' for ln(x¹) = 3* dx.

Let f(x) = = 7x¹. Find f(4)(x). -7x4 1-x
The expression f(4)(x) = -7x4(1 - x) represents the fourth derivative of the function f(x) = 7x1, which can be written as f(4)(x).
To calculate the fourth derivative of the function f(x) = 7x1, we must use the derivative operator four times. This is necessary in order to discover the answer. Let's break down the procedure into its individual steps.
First derivative: f'(x) = 7 * 1 * x^(1-1) = 7
The second derivative is expressed as follows: f''(x) = 0 (given that the derivative of a constant is always 0).
Because the derivative of a constant is always zero, the third derivative can be written as f'''(x) = 0.
Since the derivative of a constant is always zero, we write f(4)(x) = 0 to represent the fourth derivative.
As a result, the value of the fourth derivative of the function f(x) = 7x1 cannot be different from zero. It is essential to point out that the formula "-7x4(1 - x)" does not stand for the fourth derivative of the equation f(x) = 7x1, as is commonly believed.
