A=g≈-32
v=⌠a dt since a≈-32
v=-32t+C, where C is the initial velocity, which we are told is 20 ft/s
v=-32t+20
h=⌠v dt
h=-32t^2/2+20t+C, where C is the initial height, so what is a reasonable initial height? How about 3 ft since we are swinging a bat around maybe our waist level... maybe :P
h=-16t^2+20t+3
Your choices may have made a different assumption about the initial height of course but you did not show your choices, but certainly it will be:
h(t)=-16t^2+20t+hi, where hi is the initial height in feet.
This of course ignores air resistance and flight dynamics of a spinning ball with seams, which will make a significant difference in real life :)
1. The sum of b and ninety-eight
I think so the answer is D:1/4*5/8=5/32
6x + 7 = 8x - 15
7 = 2x - 15
22 = 2x
11 = x
Answer:
-6/5
Step-by-step explanation:
Slope = (y2 - y1)/(x2 - x1)
Plug in
Slope = (4 + 2)/(-2 - 3)
Slope = -6/5
