Answer:
23. 0.4583 seconds
24. 0.0107 seconds
Step-by-step explanation:
The problem statement tells you how to work it. You need to convert speed from miles per hour to feet (or inches) per second.
90 mi/h = (90·5280 ft)/(3600 s) = 132 ft/s = (132·12 in)/s = 1584 in/s
__
23. The time it takes for the ball to travel 60.5 ft is ...
time = distance/speed
time = (60.5 ft)/(132 ft/s) = 0.4583 s
It takes 458.3 milliseconds to reach home plate.
__
24. time = distance/speed
time = (17 in)/(1584 in/s) = 0.0107 s
The ball is in the strike zone for 10.7 milliseconds.

Step 1: Write equation
n - 4 = -15
Step 2: Solve for <em>n</em>
n = -11

Steps:
1. Draw a line connecting the point to the center of the rectangle
2. Then construct a perpendicular bisector to the line drawn in step 1
3. Place the compass on the midpoint of the line, adjust its length to reach the end point, and draw an arc across the circle
4. Where the arc crosses the circle will be the tangent points. So connect the endpoint to the tangent point
