Question 1034991: a ball is shot out of a homemade air cannon. it flies through the air such that its height as a function of time is given by
h=-16t^2+64t+10
where h is the height of the ball and t is the time since if was fired in seconds.
max estimates that it takes 4 seconds for the ball to hit the ground and cole estimates it takes 5 seconds. algebraically determine who is closer and support your answer.

Question 1037619: You are planning to purchase a new car and have narrowed down your search to two models:
2016 Toyota Prius costs 26800 and gets an average of 50 miles per gallon
2016 Toyota Corolla costs 17900 and gets an average of 32 miles per gallon
In either case, the dealer has offered 0% financing, and you can afford the monthly payments for either car. Assume that all costs of ownership are the same (taxes, insurance, maintenance, etc.) If gas costs 2.40 per gallon, how many miles would you have to drive for the total cost (purchase price and fuel used) of the two cars to be equal?
