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
B+c is 16
16 + 25 Is 41
I don't know d sorry
The comlement of an angle is what you add to it to get 90 degrees
x+y=90
x is the complelemt of y and y is the complement of x
so
26+complement=90
minus 26 both sides
complement=64
the complementn is 64°
