Answer:
The radius is growing at a rate of
ft per minute.
Step-by-step explanation:
From the information given we know that

And we know as well that .

Since everything is changing with the time we can compute the implicit derivative and we would get that

We are told that we are looking for how fast is the radius growing at the instant when the radius has reached 1 ft, therefore 
And when we solve for 
Answer:
yes to 5, and no to -7 (only because we are dealing with real positive numbers, not imaginary numbers). the domain is all real numbers greater than or equal to 2

Answer: 5x2-2x-7
Step-by-step explanation:
(4x2 + 3x - 1) + (x2 - 5x - 6)
=4x2+3x-1+x2-5x-6
=5x2-2x-7
