What is the inverse of the function f(x) = 4x + 8?

f^-1(x) = (x-8)/4

Step-by-step explanation:

To find an inverse function, simply flip the x and y variables in a equation and then solve in terms of y.

x = 4y + 8

x - 8 = 4y

y = (x-8)/4

And we have our final answer!

256π units²   (answer b)

step-by-step explanation:

the formula for the surface area of a sphere of radius r

is             a = 4πr²

and so, if r = 8 units, then the surface area is:

a = 4π(8 units)² = 256π units²   (answer b)

6^2 or 36

step-by-step explanation:

6000n

6×1000n

6×10^3 n

so we need 6n need to be a perfect cube

so n has to be 6^2 so that 6n is 6^3

what i'm saying is if you let n be 6^2 you have 6^3×10^3 or 60^3 which is a perfect cube
