It is A because it can’t be B and it can’t be C so my answer is A
18*3 = 54
20*3 = 60
so the scale drawing would be 54cm x 60cm
Answer:
V0 = 48 feet per second is the answer.
Step-by-step explanation:
The given function which represents height of a golf ball in feet after x seconds after a player hits it.
y = -16x² + v0x
here v0 is the initial velocity and we have to calculate initial velocity. The ball returns to the ground 3 seconds after it is hit.
After 3 seconds height of the ball will be 0.
Now from the given function
0 = -16(3)² + v0×3
3v = 16×9
v0 = 16×9/3 = 48 feet per second.
Answer= 36.75
3.75x 8 = 30
2.25x3= 6.75
6.75+30=36.75
