Answer:
D
Step-by-step explanation:
Let's find unit rate of each (number of miles traveled in 1 hour). For that we will divide the distance by time to get the unit rate.
Note: 
(A)
rate =
mph (miles per hour)
(B)
rate =
mph
(C)
rate =
mph
(D)
rate =
mph
<u>As we can see, the first 3 rates are same, 75 mph, and the last one is
mph. So clearly, the last rate is the slowest.</u>
D is the right answer.
Suppose we let
, so that
.
Also, recall the double angle identity for cosine:

So, we can rewrite and compute the integral using the substitution, as





The original price of the hat is $35. Paolo paid $28 for the hat.
So discount for the hat is $(35-28) = $7
$7 is discounted from $35. We have to find the percentage of the discount.
To find the percentage we have to divide the discount amount by the original price and then have to multiply it by 100.
So the discount percentage =
((7/35)×100) %
We can simplify 7/35 by dividing 7 and 35 both by 7. So we will get 1/5 after simplifying.
((1/5) ×100) %
(100/5)% = 20%
So the hat was discounted by 20%.
