Question

A plant is already 11.50 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) = 0.09x + 11.50

What is the plant's height after 15 months?

Answer 1

H(15)=0.09(15)+11.5
h(15)=1.35+11.5
h(15)=12.85
Final answer: 12.85m
