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.

Answer:
The answer is that x = 5.69 and y = 12.79
Step-by-step explanation:
To find x, we need use the Sin function. Sin of any angle is equal to the ratio of opposite to hypotenuse. This allows us to solve using the following equation.
Sin(ANGLE) = OPP/HYP
Sin(24) = OPP/14
14Sin(24) = OPP
5.69 = OPP
5.69 = x
We can do the same using the Cos for the adjacent side.
Cos(ANGLE) = ADJ/HYP
Cos(24) = ADJ/14
14Cos(24) = ADJ
12.79 = ADJ
12.79 = y
