Question

A zucchini plant was 13 centimeters tall when it was first planted. since then, it has grown approximately 0.6 centimeters per day.
a. write a rule to describe the function.
b. after how many days will the zucchini plant be 0.208 meters tall

Answer 1

F(x) = 0.6x + 13...this is part A (or could be written as y = 0.6x + 13)

1 meter = 100 cm....so 0.208 meters = (0.208*100) = 20.8 cm
20.8 = 0.6x + 13
20.8 - 13 = 0.6x
7.8 = 0.6x
7.8/0.6 = x
13 = x.....so for part B, ur answer is 13 days
