Answer:
Please check the explanation.
Step-by-step explanation:
Given
f(x) = 3x + x³
Taking differentiate



solving






now solving




Thus, the expression becomes


Thus,
f'(x) = 3 + 3x²
Given that f'(x) = 15
substituting the value f'(x) = 15 in f'(x) = 3 + 3x²
f'(x) = 3 + 3x²
15 = 3 + 3x²
switch sides
3 + 3x² = 15
3x² = 15-3
3x² = 12
Divide both sides by 3
x² = 4



Thus, the value of x will be:

Answer:

Answer:
It would take 69 days for the sunflower to grow 6 feet. I know this because I found the unit rate by dividing 92 by 8 which equals 11.5. Since it is a proportional relationship all i had to do was times 11.5 by 6 to get the ratio 6 feet per 69 days.
