Answer:
The correct option is D.
Step-by-step explanation:
The given graph is the graph of a cosine function, which shifts 1 unit left.
The cosine function is defined as
Where, a is amplitude, b is frequency, c is phase shift and d is vertical shift.
If c>0, then the graph shifts c units left and if c<0, then the graph shifts c units right.
Since the graph show only phase shift and the graph shifts only one unit left, therefore required function is
Option D is correct.
Corrine earns an hourly wage on top of her weekly gas allowance for her delivery job.
Her weekly earnings can be expressed as:
Earnings = 40 + 7.50h
When h=0, her earnings will be 40
This constant represents, the fixed gas allowance she is receiving for her delivery job. 7.50h represents that she get paid $7.50 for an hour of work.
So, the constant term in the expression represent her weekly gas allowance.

So if triangle ABC is similiar to triangle DEC then we know that when two figures are similar, the ratios of the lengths of their corresponding sides are equal.So we can write:
AC/DC = BC/EC =AB/DE = k
BC= 9ft + 6ft = 15
BC/EC= k
15/6=k
Now that we know the k we can find the height of the tree that's equal to AB:
AB/DE= k
AB/4=15/6
6AB= 15 x 4
AB= 60/6 = 10
The height of the tree is 10ft
