miles per hour is 
feet, what is its stopping distance for an initial speed of 
miles per hour?

(A) 
feet
(B) 
feet
(C) 
feet
(D) 
feet
(E) 
feet

(C) Seven
(D) Thirteen
(E) More than thirteen
8.
, 
, 
, 
, 
, ...
The first term of the sequence above is 
. Which of the following could be the formula for finding the 
term of this sequence for any positive integer 
?
Answer Choices
(A) 
(B) 
(C) 
(D) 
(E) 
Explanation
1.The correct answer is A
From 
is implied that 
(1)
And from 
is implied that 
(2)
If we multiply (1) and (2) together, we have that 
( 
is canceled out).
2.The correct answer is C
Let 
represent the time it took the woman to drive to work. Since her total traveling time was 
hour, the time it took her to return home is 
. The distance in miles can be found using the formula 
. The distance traveled to work is 
, and the return distance is 
. Since the distance to work is the same as the return distance, 
. Solving for 
yields 
. So the distance one way is 
miles. The total number of miles in the round trip is 
, or 
miles.
3.The correct answer is E
A line that is parallel to the
-axis and four units above the
-axis is the vertical translation of the
-axis four units upward. Since the
-axis is a horizontal line and has equation
, it follows that the line parallel to the
-axis and four units above the
-axis has equation
.
4.The correct answer is A
Since 
, it follows that 
, and so 
. Therefore, 
.
5.The correct answer is E
Each rose brings a profit of 
minus 
, or 
. The number of roses that need to be sold to make a profit of 
is 
. This is 
roses.
6.The correct answer is D
The stopping distance is directly proportional to the square of the initial speed of the car. If 
represents the initial speed of the car, in miles per hour, and 
represents the stopping distance, you have that the stopping distance is a function of 
and that 
, where 
is a constant. Since the car’s stopping distance is 
feet for an initial speed of 
miles per hour, you know that 
. Therefore, 
, and the car's stopping distance for an initial speed of 
miles per hour is 
feet.
7.The correct answer is E
The intersection of sets
and
is the set of integers that are in
and also in
. Set
consists of all positive integers that are multiples of
, and set
consists of all positive integers that are multiples of
, so the intersection of
and
is the set of positive integers that are multiples of both
and
. This is the set of all positive integers that are multiples of
. There are an infinite number of positive integers that are multiples of
, so there are more than thirteen integers in the intersection of
and
.
8.The correct answer is B
You do not know the value of the 
term or the 
term of the sequence, but you do know the values of the 
, 
, and 
terms. The correct formula must give 
as the value of the 
term, 
as the value of the 
term, and 
as the value of the 
term. Choice E, 
, gives 
, not 
, as the value of the 
term. Choice A, 
, gives 
, not 
, as the value of the 
term. Choice C, 
, gives 
, not 
, as the value of the 
term. Choice D, 
, gives 
, not 
, as the value of the 
term. This leaves choice B, 
, which gives the correct values for the
, 
, and 
terms of the sequence.
