Given f(x)= 4x^4 find f^-1(x) Then state whether f^-1(x) is a function
Answer:
The inverse is
f^-1(x) = (1/√2)x^¼
And it is a function
Step-by-step explanation:
Given f(x) = 4x^4
Let y = f(x), so that
y = 4x^4
Then dividing both sides by 4
x^4 = y/4
Taking the fourth root of both sides
x = (y/4)^¼
x = (1/√2)y^¼ = f^-1(y)
Put y = x
y = (1/√2)x^¼ = f^-1(x)
This is the inverse.
f^-1(x) is a function.
Evaluate the dot product of (3,-1) and (1,5).
Answer here
Answer:
The dot product is -2
The required dot product of (3,-1) and (1,5) is -2.
Evaluate the dot product of (3,-1) and (1,5).
What is dot product?It is a principle to combine two vectors. It tells about how much two vectors approaching in the same direction.
Now converts the coordinates to vector form.
a = 3i -1j
b = 1i + 5j
Dot product of two vectors a and b,
a.b = 3x1 - 1x5
a.b = 3-5
a.b = 2
Thus, the required dot product of (3,-1) and (1,5) is -2.

PLEASE HELP!! Using the SAS Congruence Theorem
Answer:
LAST ONE IS angle JLK congruent to angle LNM, SAS
Step-by-step explanation:
The triangles JLK and LMN are similar by SAS congruence theorem, LJK≅ LNM.
Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion .
The triangles JLK and LMN are similar triangles.
Which means the sides are proportional and those angles are congruent.
We have to prove that JLK is similar to LMN.
By SAS rule we have "if two sides in one triangle are proportional to two sides in another triangle and the included angle in both are congruent, then the two triangles are similar".
So LJK≅ LNM.

ASAP : What is the y-coordinate of the center of the circle for the following circle equation? x2 + y2 - 10y + 18x = 2
Answer:
y = 5
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre ad r is the radius
Given
x² + y² - 10y + 18x = 2 ( Rearrange collecting x and y terms together )
x² + 18x + y² - 10y = 2
Using the method of completing the square
add ( half the coefficient of the x/ y term )² to both sides
x² + 2(9)x + 81 + y² + 2(- 5)y +25 = 2 + 81 + 25
(x + 9)² + (y - 5)² = 108 ← in standard form
with centre = (- 9, 5 )
The y- coordinate of the centre is therefore y = 5

Solve dy/dx = (1-x)(1-y)
Answer:
[tex]y=1-e^{c_{2}}}*e^{-x} *e^{x^2}[/tex]
Step-by-step explanation:
We begin with the differential equation [tex]\frac{dy}{dx} =(1-x)(1-y)[/tex]
Firstly, we need to get the [tex]y[/tex] and [tex]dy[/tex] as well as the [tex]x[/tex] and [tex]dx[/tex] on the same sides as each other
To do this, we can multiply each side by [tex]dx[/tex] and divide each side by [tex](1-y)[/tex]
Doing this will give us the following differential
[tex]\frac{1}{1-y} dy=(1-x)dx[/tex]
Now, we can integrate each side
[tex]\int\limits\frac{1}{1-y} \, dy =\int (1-x) \, dx\\\\-ln(1-y)=x-x^2+c_{1}[/tex]
Now, we need to solve for y
[tex]-ln(1-y)=x-x^2+c_{1}\\\\ln(1-y)=x^2-x+c_{2} \\\\1-y=e^{x^2-x+c_{2}} \\\\y=1-e^{x^2-x+c_{2}}\\\\y=1-e^{c_{2}}}*e^{-x} *e^{x^2}[/tex]

Answer:
a
Step-by-step explanation:
it makes sence for the answer to be a because
Answer:
The amount of carbon in the trees and in the deer . . .
A) has increased.
Explanation:
Carbon is the basis for all living cells, it is responsible for the making and storing of energy. So if the number of energy storage molecules increases, the amount of carbon will increase because carbon is used to make those molecules.
Your question on carbon dioxide and photosynthesis having an effect is valid, but the loss of carbon wouldn't be much compared to the energy storage molecules, so we wouldn't consider that a factor in this case.
