Shown in the Figure below

Step-by-step explanation:

In this exercise, we have the following system of inequalities:

$x$

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 $x\geq -1$ and this is represented by the closed circle. On the other hand, the number 3 is not included in the solution because $x$ and this is represented by the open circle.

Answer:

The goalkeeper has 0.306 seconds to react, dive, and reach the ball before it crosses the goal line.

Step-by-step explanation:

We use the following relation to solve this question:

$v = \frac{d}{t}$

In which v is the velocity, d is the distance, and t is the time.

Chastain will kick the ball from 18 yards away from the goal at 120 miles per hour.

Since the velocity is in miles per hour, the distance has to be in yards.

Each yard has 0.000568182 miles, so the ball will be kicked from 18*0.000568182 = 0.0102 miles.

This means that $v = 120, d = 0.0102$

How many seconds does the goalkeeper have to react, dive, and reach the ball before it crosses the goal line?

We have to find t, first in hours. So

$v = \frac{d}{t}$

$120 = \frac{0.0102}{t}$

$120t = 0.0102$

$t = \frac{0.0102}{120}$

$t = 0.000085$

An hour has 3600 seconds. So

3600*0.000085 = 0.306.

The goalkeeper has 0.306 seconds to react, dive, and reach the ball before it crosses the goal line.
