a.
To find: the initial height of the arrow.
a.

Answer to Problem 42E
1.5 meters
Explanation of Solution
Given information:
The graph showing the path of the arrow is:
Calculation:
The y -intercept of the given graph gives the initial height of the arrow.
By observing the given graph it can be said that the y -intercept is
So, the initial height of the arrow is 1.5 meters.
b.
To estimate: the maximum height of the arrow.
b.

Answer to Problem 42E
Approximately 1.6 meters.
Explanation of Solution
Given information:
The graph showing the path of the arrow is:
Calculation:
Consider the given graph,
From the above graph it can be observed that the maximum height is approximately 1.6 meters.
c.
To find: the distance travelled by the arrow.
c.

Answer to Problem 42E
90 meters
Explanation of Solution
Given information:
The graph showing the path of the arrow is:
Calculation:
The x -intercept of the given graph gives the distance travelled by the arrow.
By observing the given graph it can be said that the x -intercept is
So, the distance travelled by the arrow is 90 meters.

They are playing a game where they randomly pick a card out of the hat four times, with replacement. Amy thinks that the probability of getting exactly two aces in four picks is equal to the probability of not getting exactly two aces in four picks. Samiha disagrees. She thinks that the probability of not getting exactly two aces is greater. The sample space of possible outcomes is listed below. A represents an ace, and K represents a king. Who is correct?arrow_forward
