Answer:
(0 + m)/2, (0 + n)/2.
Step-by-step explanation:
The x coordinate of the midpoint must be halfway between the x coordinates of A and B, and the y coordinate must be found in the same way.
So the midpoint is (0 + m)/2, (0 + n)/2.
Answer:
Pretty sure it is 18 girls
Step-by-step explanation:
81 girls: 72 boys
72 boys /16 boys = 4.5
81 girls / 4.5= 18 girls
so 18 girls:16 boys
pls mark me brainliest :)
They both are the same exact weight 907.2 kilograms is 2,000 pounds.
The solution to the problem is as follows:
<span>cos2A - cos4A = -2 sin(6A/2).sin(-2A/2) = +2 sin(3A).sinA
and
sin4A - sin2A = 2 cos(6A/2).sin(2A/2) = 2 cos(3A).sinA
Hence RHS = (cos(2A)-cos(4A))/ (sin(4A)- Sin(2A)) = sin 3A / cos 3A = tan 3A = LHS
