4 because 8-4 is 4 and that's it
Answer:
5 feet
Step-by-step explanation:
The function which governs the T-shirt's height y, in feet, after x seconds is given as:
![y = -16x^2+72x + 5](https://tex.z-dn.net/?f=y%20%3D%20-16x%5E2%2B72x%20%2B%205)
We want to determine the starting height of the T-Shirt. This occurs at x=0.
When x=0
![y = -16(0)^2+72(0) + 5\\y= 5$ feet](https://tex.z-dn.net/?f=y%20%3D%20-16%280%29%5E2%2B72%280%29%20%2B%205%5C%5Cy%3D%205%24%20feet)
The starting height of the t-shirt is 5 feet.
