Good luck on your assignment
Sample Response: The object will hit the ground after 5 seconds. You can rewrite the quadratic function as a quadratic equation set equal to zero to find the zeros of the function 0 = –16t2 + 80t + 0. You can factor or use the quadratic formula to get t = 0 and t = 5. Therefore, it is on the ground at t = 0 (time of launch) and then hits the ground at t = 5 seconds

Answer:
6%
Step-by-step explanation:
19.20 = 320x (suppose x = tax rate)
Divide both sides by 320
x = .06 or 6%
