How would you find the equation for the rate of change in volumes between two concentric spheres with progressing time given the radius as a function of time. I tried just subtracting the two volumes, but ofcourse thats wrong. In your answer please substitute the radius with r(t). Thanks.

This is my test: (please tell me if these are correct, and then what would I get in the test according with my answers)
The colon ( : ) means division
The star ( * ) means multiplication
The v ( ^ ) means exponent. 4^5 would be four to the power of five.
Here goes:

8(2-5)^3 : 6^2
I got -6.

(7/8 * 3/5) : (1/5 - 1/2)
I got -7/4.

3/5 * (2-1/3) + 1/6 : 1/2
I got 4/3.

Simplify, don't calculate: (2 + 1/3)^-2 * 3^-2
I got 7-2.

(5/2 - 5/6 + 2/3 * 1/3) : [2 - 1/2 * (1 + 5/3)]
I got 51/18.

Simplify don't calculate: (6^2 * 3^2) : [2^3 * (-3)^2 * 4^2]
I got (3^2) : (2^5).

Thanks in advance :)

HELP! How do I use composition to verify that f and g are inverses of each other? Let f(x)= (2x)/(3-x) and g(x)=(3x)/(x+2)

Thanks So Much!

Find the Limit as x ->infinity of (1 + (10/x))^4x

I've gotten that it is a 1 ^ Infinity form but do not know where to go from there besides taken the natural log of each side(?)

Ln y = Ln (1 + (10/x))^4x

Thats how far I got
