Question

A plant is already 14.25 meters tall, and it will grow 20 centimeters every month. The plants height, H (in meters) after x months is given by the following function.H (x) =0.20x+14.25What is the plants height after 20 months?

Answer 1

As given by the question

There are given that the equation

`H(x)=0.20x+14.25`

Now,

From the equation, H is the height of the plant and x is the months.

Then,

The plants height after 20 months,

Put x =20 into the given equation

So,

`\begin{gathered} H(x)=0.20x+14.25 \\ H(x)=0.20*20+14.25 \\ H(x)=4+14.25 \\ H(x)=18.25 \end{gathered}`

Hence, the plants height after 20 months is 18.25 meters.
