Answer:
<h3>1 secs</h3>
Step-by-step explanation:
Given the height of the discus can be modeled by the equation y=−16x
^2
+32x+4, where y represents the height in feet of the discus in seconds, the velocity of the discus at its maximum height is zero.
Velocity v = dy/dx = 0
dy/dx = -32x + 32
0 = -32x + 32
32x = 32
x = 1 secs
Hence it will take the discus 1 secs to reach its maximum height
Answer:
-18
Step-by-step explanation:
Given:
f(x)=4-x^2 and g(x) =6x
h(3) = (g-f)(3)
= 6x - (4x^2)
= 6*3 -(4*3^2)
= 18 - 4*9
= -18
