I would expect the data to be positively correlated bc the higher something is the bigger base it needs the feet are the base of the human body so...
Use the number and increase it by 35% then multiply them
Answer:
6216.66
Step-by-step explanation:
(8*40)+6%*×=$692; 320 + 0.6x = 692; .6×=692-320; 0.6x=373; ×=373÷.6; x=6216.66
Step-by-step explanation:
cos(3x) − 3 cos x = cos(2x) + 1
Use triple and double angle formulas.
(4 cos³x − 3 cos x) − 3 cos x = (2 cos²x − 1) + 1
Simplify.
4 cos³x − 6 cos x = 2 cos²x
4 cos³x − 2 cos²x − 6 cos x = 0
2 cos³x − cos²x − 3 cos x = 0
Factor.
cos x (2 cos²x − cos x − 3) = 0
cos x (cos x + 1) (2 cos x − 3) = 0
Solve.
cos x = 0 → x = 90°, 270°
cos x + 1 = 0 → x = 180°
2 cos x − 3 = 0 → no solution
Answer:
the answer is A. 36
Step-by-step explanation:
because the rectangles are proportionate, I set up ratios.
90:75 so h:30
from there I did 70/30 because those sides are proportionate to each other and this got me 2.5. then I did 90/2.5 to get 36
