Question

A plant is already 13.50 meters tall, and it will grow 25 centimeters every month. the plants height H ( in meters), after x months is given

H(x)=0.25x+13.50

what is the plants height after 30 months?

Answer 1

21.0metres

Explanation:

Given the height of a plant that is already 13.50 meters tall and grows 25 centimeters every month modeled by the equation H(x)=0.25x+13.50,where x is the number of months. To find the plants height after 30 months, we will substitute x = 30 into the modeled equation as shown;

H(x)=0.25x+13.50

H(30)=0.25(30)+13.50

H(x)= 21.0

Hence the plants height after 30 months is 21.0metres

H(x)=7.5+13.50
