Answer:
Step-by-step explanation:
4. (6^10)^-7 is when the exponents should be multiplied
answer is B
5. (7^3)^-2 = (7^-6)
1/7^6 = 1/(7x7x7x7x7x7)
answer is A
2. 11^-4/11^8= 1/11^(8+4) = 1/11^12
answer is A
3. (2^5/3^2)^4= 2^20/3^8
answer is A

Answer:
So the radius is increasing at
.
This is approximately 0.00497 cm/min that the radius is increasing.
Step-by-step explanation:

The volume and radius are both things that are changing with respect to time.
So their derivatives will definitely not be 0.
Let's differentiate:

I had to use constant multiple rule and chain rule.
We are given
and
.
We want to find
.
Let's plug in first:



Multiply both sides by 3:


Divide both sides by
:


So the radius is increasing at
.
This is approximately 0.00497 cm/min that the radius is increasing.
Answer:
<u>0.125 miles per gallon.</u>
Step-by-step explanation:
After 200 gallons used the freight train has traveled 25 miles. This means that we need to divide both sides by 200 to get a singular gallon's worth of miles traveled. 200/200 is 1, and 25/200 is 0.125.

---------------------
<u><em>IF</em></u> it were how many gallons per mile, you would divide both answers by 25 resulting in <u>8 gallons per mile.</u>
