Step-by-step explanation:
From the graph, we obtain the trigonometric function as:

The corresponding cosine function have equation.

This function is of the form: 
where
is the amplitude.
Therefore the amplitude is |2|=2

Answer:
After 6 days Martha biked 330 miles, while Enrico biked 290 miles.
Step-by-step explanation:
i. Martha bikes 55 miles per day.
So that after 6 days, Martha would have covered;
55 miles x 6 = 330 miles
After 6 days, Martha would have biked 330 miles.
ii. Enrico bikes 145 miles every 3 days.
Then after 6 days, Enrico would have covered;
x 145 miles
= 2 x 145 miles
= 290 miles
After 6 days, Enrico would have biked 290 miles.
After 6 days Martha biked 330 miles, while Enrico biked 290 miles.
Assuming you are asking how many weeks, than the answer would be 17-32, because at 16 weeks the growth would be 4 cm, totaling at 11, but you need more than 11cm, and at 32 weeks it's at 15 cm.
