Final answer:
To find the value of (h(2)-h(1))/2-1 using the function h(t)=-16t²+80t, substitute the values of t into the equation and simplify.
Step-by-step explanation:
To find the value of (h(2)-h(1))/2-1 using the function h(t)=-16t²+80t, we need to substitute the values of t into the equation and simplify. Let's start by finding h(2) and h(1):
h(2) = -16(2)²+80(2) = -64+160 = 96
h(1) = -16(1)²+80(1) = -16+80 = 64
Now let's substitute these values into the expression:
(h(2)-h(1))/2-1 = (96-64)/2-1 = 32/2-1 = 16-1 = 15
