John hit a golf ball from the ground and it followed the projectile h(t) =− 16t² + 100t + 0 , where t is the time in seconds, and ℎ is the height of the ball.
1. Use the quadratic formula to solve the two roots. These represent the 2 times that the ball is on the ground. At what time does the golf ball land?
2. What is the max height of the golf ball?

3. At what time (t) is the golf ball at the maximum height?

Joel wants to buy a new tablet computer fram a store having a 20% off sale on all tablets. the tablet he wants has an original cost of $190. he also wants to make sure he has enough money to pay the 5% sales tax. part one joel uses the incorect expression 0.95(190)(0.8) to calculate that the tablet will cost him a total of $144.40. describe his error and write the correct expression part two how much will joel pay for the tablet show your work if you answer this question correctly you will receive a prize of 99 points good luck
