Question

a plant is already 15.50 meters tall, and it will grow 9 cen month. the plants height, h (in meters), after x month following. h = 0.09x + 15.50 what is the plants height after 15 months?

Explanation:

Step1: Identify the value of x

We are given that the number of months \( x = 15 \).

Step2: Substitute x into the formula

The formula for the height of the plant is \( H = 0.09x + 15.50 \). Substitute \( x = 15 \) into the formula:
\( H = 0.09\times15 + 15.50 \)

Step3: Calculate the multiplication part

First, calculate \( 0.09\times15 \). \( 0.09\times15 = 1.35 \)

Step4: Calculate the final height

Now, add this result to 15.50: \( H = 1.35 + 15.50 = 16.85 \)

Answer:

The plant's height after 15 months is 16.85 meters.
