ANSWER
-2 shift the graph of the basic function down by 2 units.
EXPLANATION
The given cosine function is:

This equation can be rewritten as:

We compare this to

The effect d has on the graph is that, it shifts the graph up by d units.
If d is negative the graph shifts down by d units.
Since d=-2, the graph will shift down by 2 units.
You do 3/15 which is 0.2
then 0.2*20 which is 4
you can expect 4 to win a prize
hope this helps and you rate me good;)
Answer:
227 sides
Step-by-step explanation:
The sum of the interior angles of a convex polygon is S=180(n-2) where n is the number of sides. If S=40500, then we have our equation 40500=180(n-2) and we can solve for n:
40500 = 180(n-2)
225 = n-2
227 = n
Therefore, the number of sides in the regular polygon is 227.
Answer: 1.834 ft
Step-by-step explanation:
Given
Walter's first Jump is 5 ft, 9 in.
His second Jump is 3 ft, 11 in.
We know,

Converting inches to feet
First Jump in feet

Second jump

The difference in the measurement of two Jumps is

So, Walter first Jump is 1.834 ft higher than the second Jump
In the given equation above, it can be deduced that 2 subtracted from 3 times Yuri's age is equal to the age of Karina which was given to be twelve. This statement is similar to that which is given in the choice number four. Thus, the answer is D.
