Answer:
100feet
Step-by-step explanation:
Given the height reached by a dolphin expressed by the equation is h = -16t^2 + 80t. At maximum height, the velocity is zero, hence;
v(t) = dh/dt = -32t + 80
0 = -32t + 80
32t = 80
t = 80/32
t = 2.5secs
Substitute t = 2.5 into the height formula h = -16t^2 + 80t
h = -16(2.5)^2 + 80(2.5)
h = -100+200
h = 100feet
Hence  the maximum height the dolphin jumps is 100feet
 
        
             
        
        
        
Answer:
This system has no points of intersection.
Step-by-step explanation:
The lines are parallel, so they don't intersect.
I graphed the equations below to show you how they are parallel.
