Aball is thrown upward. its height ( h, in feet ) is modeled by the function h = -16t^2 + 64t+3, where t is the length of time ( in seconds ) that the ball has been in the air. what is the maximum height the ball reaches? a ball is thrown upward. its height ( h, in feet ) is modeled by the function h = -16t^2 + 64t+3, where t is the length of time ( in seconds ) that the ball has been in the air. what is the maximum height the ball reaches?

To find the maximum height just simply find the vertex of  -16t^2 + 64t + 3 and to find the axis of symmetry or the x value of the vertex do -b/2a or -64/-32 = 2 in this situation. Plug in to get the y value -16(2)^2 + 64(2) + 3 = 67 Vertex (2,67) So the max height is 67 feet (takes 2 seconds to do so)

Lets look at the information we have:-

6.8 pounds on Sunday
8.75 pounds on Monday
How many pounds did he collect together on these 2 days?

Add:-

6.8 + 8.75 = 15.55
Dan collected 15.55 pounds of aluminum on these 2 days. 

CHECK OUR WORK:-

15.55 - 8.75 = 6.8
We were RIGHT!! 

So, Dan collected 15.55 pounds of aluminum on these 2 days. 

Hope I helped ya!! xD
