Question

The path of a football kicked by a field goal kicker can be modeled by the equation y = -0.04x2 + 1.56x, where x is the

Answer 1

Answer:

45.63

Step-by-step explanation:

Answer 2

Answer:

19.5 yd

Step-by-step explanation:

To khown the maximum height we must derivate the function and see when the derivated function equals 0

Let f be our function : f(x)= -0.04x²+1.56x ⇒f'(x)= -0.08x+1.56

• f'(x)= 0 ⇒ -0.08x+1.56 =0 ⇒1.56= 0.08 ⇒ x= 1.56/0.08 ⇒ x=19.5
• so the maximum height is 19.5 yd
