Answer:
2.236
Step-by-step explanation:
You need to use the distance formula.
d= square root of (x2-x1)^2=(y2-y1)^2
<span>The answer is a. cos2x - sin2x - sin x. Use the rule: cos2x = (cos^2)x - (sin^2)x. So, substitute cos2x in the expression: cos2x - sinx = ((cos^2)x - (sin^2)x) - sinx = (cos^2)x - (sin^2)x - sinx. Therefore, choice a. is correct choice.</span>
Answer:
112.5 square feet
Step-by-step explanation:
a square has equal sides so divide 225 by 2
Answer:
(A) It would have to lie on AB because DC would rotate halfway around M. B would lie on D and A would lie on C.
(B) AD would lie on the BC line. D would lie on B and A would lie on C.
(C) The Lines CD and AD would only intersect if one line had to rotate 180 degrees around M.
He started with 16 because he sold half so add half and that would be 16 ;)
