Answer:
i say maybe c
Step-by-step explanation:
12, 24, or 26 is a common denominator
The general equation for height is:
h = -0.5gt^2 + (v0)t + h0, where g = -9.8 m/s^2 or -32 ft/s^2, v0 = initial velocity, and h0 = initial height.
1) h = -4.9t^2 + 19: -4.9 means the units are in meters, and 19 means that the initial height was 19 m, which is group C.
2) -16t^2 means the units are in feet, and 50t means that the initial velocity was 50 ft/s upwards. This is group B.
3) -16t^2 again means the units are in feet, and 50 means the initial height was 50 ft. This is group D.
4) -4.9t^2 means the units are in meters, and 19 is the initial height of 19 m. This is for group A.
12 is the greatest common factor.
Answer:
L = (P - 2W) / 2
Step-by-step explanation:
Given:
P = 2L + 2W
Where,
P = perimeter of a rectangle
L = length of the rectangle
W = width of the rectangle
Make L the subject of the formula
P = 2L + 2W
Subtract 2W from both sides
P - 2W = 2L + 2W - 2W
P - 2W = 2L
Divide both sides by 2
(P - 2W) / 2 = 2L / 2
L = (P - 2W) / 2
The answer is L = (P - 2W) / 2
