Answer to Problem 86PPE
Explanation of Solution
Given information:
S throws a ball in the air. The graph shows the height of the ball as a function of time.
N also throws a ball in the air. His throw begins at a height of 2 feet. The ball travels up to 30 feet in 2 seconds and then comes back down to the ground after 4 seconds.
Calculation:
Both balls come down after 4 seconds means there is time in axis.
Hence,

Explanation of Solution
Given information:
S throws a ball in the air. The graph shows the height of the ball as a function of time.
N also throws a ball in the air. His throw begins at a height of 2 feet. The ball travels up to 30 feet in 2 seconds and then comes back down to the ground after 4 seconds.
Calculation:
Both balls do not start from same height as N’s ball beings at the height of 2 feet from the ground but S’s ball beings from ground. Hence both are at different height. Show the graph also.

To find: the ball which goes higher in the air.

Answer to Problem 86PPE
N’s ball will go heigher in the air.
Explanation of Solution
Given information:
S throws a ball in the air. The graph shows the height of the ball as a function of time.
N also throws a ball in the air. His throw begins at a height of 2 feet. The ball travels up to 30 feet in 2 seconds and then comes back down to the ground after 4 seconds.
Calculation:
N’s ball will go heigher in the air as both ball travels 30 feet in 2 seconds but N’s ball is ready at height of 2 feet from the so its total height will be 32 feet.

- A vacant lot is being converted into a community garden. The garden and a walkway around its perimeter have an area of 690 square feet. Find the width of the walkway (x) if the garden measures 14 feet wide by 18 feet long. Write answer to 2 decimal places. (Write the number without units). Hint: add 2x to each of the garden dimensions of 14 x 18 feet to get the total area for the length multiplied by width.arrow_forwardSolve x-1 x+2 = 12 3 4 Your Answer: Answerarrow_forwardFind the solutions to the following equation 21x²+5x=6 ○ a) -3/7, 3/2 ☐ b) -2/3, 3/7 ○ c) -7/3, 3/2 ○ d) -2/3, 7/3arrow_forward
