Ответ:
the rate is equal to![3.2\frac{inches}{week}](/tpl/images/0069/6079/630d8.png)
Step-by-step explanation:
we have
where
h is the height of a plant
t is the number of weeks after planting
so
Find the rate at which the plant's height is increasing
we know that
The given formula is a linear equation
The rate is equal to the slope of the linear equation
Isolate the variable h
the slope is equal to![m=3.2\frac{inches}{week}](/tpl/images/0069/6079/2e07e.png)
therefore
the rate is equal to![3.2\frac{inches}{week}](/tpl/images/0069/6079/630d8.png)
