Answer:
120
Step-by-step explanation:
15 x 16/2
You double 8 because your rotating around the y-axis
Divide miles by 60 to convert it to miles per minute because there are 60 minutes in an hour.
f(x) = 5x²
f(10) = 5(10)² = 5(100) = 500
f'(x) = 10x
f'(10) = 10(10) = 100
Now, find the line that passes through (10, 500) and has a slope of 100
y - y₁ = m(x - x₁)
y - 500 = 100(x - 10)
y - 500 = 100x - 1000
y = 100x - 500
