Answer:

3k/2 - k+3/3=8- k+2/4

(3k/2)x3 - (k+3/3)x2=(8)x4 - k+2/4

9k-2k-6/6 = 32-k-2/4

7k-6/6 = 30-k/4

(7k-6)x4 = (30-k)x6

28k - 24 = 180 - 6k

34k = 204

k = 204/34

k=6

Step-by-step explanation:

First, you multiply both sides by the numbers there to both the numerator and denominator, to get the same denominator. Then, simplify the answers in the second step. Next, cross multiply by multiplying the numerator of the left side to the denominator of the right side; and multiplying the numerator of the right side of the denominator of the left side. When you reach the fifth step, move -6k to the left side it will turn to +6k and add with 28k to get 34k. Move -24 to the right side it will turn +24 and add with 180 to get 204. Lastly, divide 204 by 34 to get k = 6.

Step-by-step explanation:

the x value comes from the slope when graphing. for example, the slope on this problem is just x which means its only one. so you move up one and to the right one. for the second equation, its negative so you move back one or down one. the x value coms from when they are both intercepted when graphed.

By using the concept of compact set, it can be proved that

|f(x)−f(y)|≤A∥x−y∥+ϵ,∀x,y∈K.

What is compact set?

A set K is said to be compact if every open cover of K has a finite subcover.

Let K⊆Rn is compact  f:K→R is continuous, and ϵ>0

Let there exist [tex]x_n, y_n[/tex] ∈ K such that |f([tex]x_n[/tex])−f([tex]y_n[/tex])| > n∥[tex]x_n[/tex]−[tex]y_n[/tex]∥+ϵ,

Since K is compact there is a subsequence [tex]x_{nk}[/tex] and [tex]y_{nk}[/tex] of [tex]x_n, y_n[/tex] respectively such that [tex]x_{nk}[/tex] converges to x and [tex]y_{nk}[/tex] converges to y.

So,  |f([tex]x_{nk}[/tex])−f([tex]y_{nk}[/tex])| > [tex]n_k[/tex]∥[tex]x_{nk}[/tex]−[tex]y_{nk}[/tex]∥+ϵ,

Since f is continuous,

We can write

|f(x)−f(y)| > [tex]n_k[/tex]∥x - y∥+ϵ,

This is true for infinite many [tex]n_k[/tex]

So ||x - y|| = 0

|f(x) - f(y)| > ϵ, a contradiction since f is continuous

So,  there is a number A>0 such that

|f(x)−f(y)|≤A∥x−y∥+ϵ,∀x,y∈K.

The distance between the two points (5,5) and(-1,-3) is 10 from the distance formula.

Given that,

The points area (5,5) and (-1,-3)

We have to find the distance between the two points.

We know that,

The distance between two points is the length of the line segment spanning those two points on the plane.

d=√((x₂ - x₁)² + (y₂ - y₁)²) is a common formula to calculate the distance between two points.

Any two points on an x-y plane or coordinate plane can have their separation between them determined using this equation.

We get,

(5,5) and (-1,-3)

Distance= [tex]\sqrt{(-1-5)^{2}+(-3-5)^{2} }[/tex]

Distance= √(-6)²+((-8)²

Distance= √36+64

Distance= √100

The 200 km, 100 km, and 400 km distances traveled by the airplane at bearings of 335°, 170°, and 288°, respectively, indicates;

a) The displacement of the airplane when it lands is 485.56 kilometers

b) The bearing the airplane could have flown to complete the journey directly is 288.27°

A bearing is the measurement in degrees of an angle from the north direction

a) The path of the airplane can be represented using vectors as follows;

A bearing of 335° = N 25° W

Therefore;

[tex]\vec{d_1}[/tex] = -200·sin(25°)·i + 200·cos(25°)·j

A bearing of 170° = S 10° E

Therefore;

[tex]\vec{d_2}[/tex] =  100·sin(10°)·i - 100·cos(10°)·j

A bearing of 280° = N 80° W

Therefore;

[tex]\vec{d_3}[/tex] = -400·sin(80°)·i + 400·cos(80°)·j

The resultant displacement of the airplane, can be found by adding the above displacement vectors as follows;

R = (100·sin(10°)-200·sin(25°) - 400·sin(80°))·i + ((200·cos(25°) - 100·cos(10°) + 400·cos(80°))·j = -461.08·i + 152.24·j

The distance of the airplane from the start is therefore;

|R| = √((-461.08)² + 152.24²) ≈ 485.56

b) The direction of the airplane obtained from the resultant vector can be presented as follows;

[tex]\theta = arctan\left(\dfrac{152.24}{-461.08\right)}\approx -18.27^{\circ}[/tex]

From the other possible values of the angle, θ, we get;

θ = 180° - 18.27° ≈ 161.73°

The 161.73° is measures from the positive x-axis, and therefore is in Quadrant II

The bearing is therefore 270° + the measure of the 161.73° above the negative x-axis, which indicates;

The bearing = 270° + 180° - 161.73° = 288.27°

What is Maclaurin series?

Given the values of the function's successive derivatives at zero, a Maclaurin series is a power series that enables one to construct an approximation of a function with input values close to zero.

We will utilize the common power series representation of the functions, such as sine and the logarithmic function, to find the first three non-zero terms of the Maclaurin series representation for the function. We shall multiply the terms of each expression to obtain the final expression.

[tex]sin(x) = x -\frac{x^3}{3!}+\frac{x^5}{5!} +\frac{x^7}{7!} +........= \sum_{n=0}^{\infty} (-1)^n\ \frac{x^{2n+1}}{(2n+1)!}[/tex]

The angular velocity of a person standing on the equator is ω = 1.026 × 10⁻⁴ rad/s

Angular velocity is the number of revolution per second of an object.

Since a planet rotates through one complete revolution every 17 hours and since the axis of rotation is perpendicular to the equator, you can think of a person standing on the equator as standing on the edge of a disc that is rotating through one complete revolution every 17 hours. We thus require its angular velocity.

The angular velocity is given by ω = 2π/T where T = period of revolution

Since the planet rotates through one complete revolution every 17 hours, its period, T = 17 hours = 17 h × 60 min/h × 60 s/min = 61200 s

So, substituting the period into the equation for the angular velocity, we have

ω = 2π/T

ω = 2π/61200 s

ω = π/30600 s

ω = 0.0001026 rad/s

ω = 1.026 × 10⁻⁴ rad/s

The exponential or the future value with interest is A = $ 856

The exponential growth or decay formula is given by

x ( t ) = x₀ × ( 1 + r )ⁿ

x ( t ) is the value at time t

x₀ is the initial value at time t = 0.

r is the growth rate when r>0 or decay rate when r<0, in percent

t is the time in discrete intervals and selected time units

Given data ,

Let the future value be represented as A

To calculate the future value of $800 after one year with an interest rate of 7%, we can use the formula for simple interest:

The future value = present value x (1 + (interest rate x time))

So , the exponential equation is

x ( t ) = x₀ × ( 1 + r )ⁿ

Plugging in the values we have:

The future value = $800 * (1 + (0.07 * 1))

The future value = $800 * 1.07

The future value = $856

Hence , the future value of $800 one year from today with a 7% interest rate would be $ 856
