Answer:

Step-by-step explanation:

(0, 1) (1, -1)

(-1 - 1)/(1 - 0) = -2/1 = -2

y - 1 = -2(x - 0)

y - 1 = -2x + 0

y = -2x + 1

Answer:

314.16

Step-by-step explanation:

Because we have the radius given to us by BC, we can simply input it into the formula to find the area of a circle, pi(r)^2.

After we insert the given radius, we have pi(10)^2.

We can simply input it into our calculator to find the answer.

Which of the following is the inverse of y = 2^3x + 1

Elena L [17]

The choices are missing, but we can find the right answer by using the given function

The inverse of $y=2^{3x}+1$ is $y=\frac{1}{3}[\frac{log(x-1)}{log(2)}]$

Step-by-step explanation:

Let us revise the steps of finding the inverse of a function

Write the function in the form of y = f(x)
Switch x and y
Solve to find the new y

∵ $y=2^{3x}+ 1$

- Switch x and y

∴ $x=2^{3y}+1$

- Subtract 1 fro both sides

∴ $x-1=2^{3y}$

- Insert ㏒ in both sides

∴ $log(x-1)=log(2^{3y})$

- Remember $log(a^{n})=n.log(a)$

∵ $log(2^{3y})=(3y).log(2)$

∴ $log(x-1)=(3y).log(2)$

- Divide both sides by ㏒(2)

∴ $\frac{log(x-1)}{log(2)}=3y$

- Divide both sides by 3

∴ $\frac{1}{3}[\frac{log(x-1)}{log(2)}]=y$

- Switch the two sides

∴ $y=\frac{1}{3}[\frac{log(x-1)}{log(2)}]$

The inverse of $y=2^{3x}+1$ is $y=\frac{1}{3}[\frac{log(x-1)}{log(2)}]$
