Question

A plant is already 12.00 meters tall, and it will grow 9 centimeters every month. The plant's height, H (in meters), after x months is given by the following function. H (x) = 12.00 + 0.09x

What is the plants height after 40 months?​

Answer 1

15.6 meters

Explanation:

We are given the expression H(x) = 12.00 + 0.09x where:

12.00 m is the plant's initial height

0.09 cm is the amount the plant grows every month

x is the amount of months that have passed

H is the plant's height (in meters)

We are asked to find the plant's height after 40 months. To solve, we substitute the variable x with 40 and follow our order of operations.

H(40) = 12.00 + 0.09(40)

H(40) = 12.00 + 3.6

H(40) = 15.6

The plant's height is 15.6 meters after 40 months.
