Shown in the Figure below
Step-by-step explanation:
In this exercise, we have the following system of inequalities:
The word and means intersection, so both inequalities must be true at the same time. We can graph this system as indicated in the figure below. Indeed, there is intersection between -1 and 1. Also, the number -1 is included in the solution because and this is represented by the closed circle. On the other hand, the number 3 is not included in the solution because
and this is represented by the open circle.

Answer:
c. 6.5 seconds.
Step-by-step explanation:
We have been given that a a paper plane is thrown from the top of a 147-foot cliff into the water below, the height of the plane at any given time can be determined by the formula , where h is the height of the plane at t seconds.
To find the time, when plane will be at a height of exactly 20.25 feet, we will substitute in our given formula and solve for t as:
Take square root of both sides:
Since time cannot be negative, therefore, the plane will be at a height of exactly 20.25 feet after 6.5 seconds and option 'c' is the correct choice.
