Question

Because of the rainy season, the depth in a pond increases 3% each week. Before the rainy season started, the pond was 10 feet deep. What is the function that best represents the depth of the pond each week and how deep is the pond after 8 weeks? Round your answer to the nearest foot. Hint: Use the formula, f(x) = P(1 + r)x. f(x) = 10(0.03)x, 36 feet f(x) = 10(1.03)x, 14 feet f(x) = 10(1.3)x, 37 feet f(x) = 10(1.03)x, 13 feet

Answer 1

D.

Explanation:

Answer 2

f(x) = 10(1 + 0.03)x =
f(x) = 10(1.03)x

after 8 weeks...
f(8) = 10(1.03^8) = 10(1.267) = 12.67 rounds to 13 ft
