Answer:

<h2>h(x) = 72t - 16t^2 h in feet - t in seconds</h2><h2 /><h2>This is a formula that models the velocity of a thrown ball.</h2><h2 /><h2 /><h2 /><h2>When the ball has reached the maximum height acceleration is 0.</h2><h2 /><h2 /><h2 /><h2>The formula for the acceleration for this equation is the derivative of the original equation.</h2><h2 /><h2>This equation is 72 - 32t.</h2><h2 /><h2>Set the equation to 0.</h2><h2 /><h2 /><h2 /><h2>0 = 72 - 32t t in seconds</h2><h2 /><h2 /><h2 /><h2>32t = 72</h2><h2 /><h2>t = 2.25 seconds.</h2><h2 /><h2 /><h2 /><h2>Subtitute 2.25 into the original equation.</h2><h2 /><h2>72(2.25) - 16(2.25^2) = h in feet</h2><h2 /><h2>162 - 16(5.0625) = h in feet</h2><h2 /><h2>162 - 81 = h in feet</h2><h2 /><h2>81 feet = h</h2>

Referring to the figure, find the value of x
mestny [16]

Answer:

x = 18

Step-by-step explanation:

All triangle angles add up to 180 so:

x + 5x + 72 = 180

6x + 72 = 180

6x = 180 - 72

6x = 108

x = 18
