Step-by-step explanation:
Given : ![H = -16t^{2} +64t](https://tex.z-dn.net/?f=H%20%3D%20-16t%5E%7B2%7D%20%2B64t)
To Find: How many seconds does it take for the golf ball to hit the ground?
Solution :
Since we are given an equation : ![H = -16t^{2} +64t](https://tex.z-dn.net/?f=H%20%3D%20-16t%5E%7B2%7D%20%2B64t)
Where H denotes height
t denotes the number of seconds elapsed since the ball was hit.
When he golf ball to hit the ground at that time the height becomes 0
So, put H = 0 in the equation
![H = - 16t^{2} +64t](https://tex.z-dn.net/?f=H%20%3D%20-%2016t%5E%7B2%7D%20%2B64t)
![0 = - 16t^{2} +64t](https://tex.z-dn.net/?f=0%20%3D%20-%2016t%5E%7B2%7D%20%2B64t)
![16t^{2} = 64t](https://tex.z-dn.net/?f=16t%5E%7B2%7D%20%3D%2064t)
![16t = 64](https://tex.z-dn.net/?f=16t%20%3D%2064)
![t =\frac{64}{16}](https://tex.z-dn.net/?f=t%20%3D%5Cfrac%7B64%7D%7B16%7D)
![t =4](https://tex.z-dn.net/?f=t%20%3D4)
Thus it take 4 seconds for the golf ball to hit the ground

Answer:
$44
Step-by-step explanation:
Original price = $80
Discount on sale = 50%
Discounted price = (1 - 50%) * original price
Discounted price = 0.5 * $80 = $40
Sales tax = 10%
Sales tax amount = 0.1 * $40 = $4
Total cost = discounted price + sales tax amount
Total cost = $40 + $4 = $44
