If I am correct the answer is 369,600 feet per hour.
answer
10
step-by-step explanation
the equation given is sin(x) = cos(y) with x = 2k + 3 and y = 6k + 7
substitute in 2k+ 3 for x in sin(x) and substitute in 6k + 7 for y in cos(y)
sin(x) = cos(y)
sin(2k + 3) = cos(6k + 7)
we know that sin(x) = cos(90 -x)
sin(2k + 3)
= cos(90 - (2k + 3) )
= cos(90 - 2k - 3)
= cos(87 - 2k)
substitute this into the equation sin(2k + 3) = cos(6k + 7)
sin(2k + 3) = cos(6k + 7)
cos(87 - 2k) = cos(6k + 7)
87 - 2k = 6k +7
80 = 8k
k = 10
Answer:
165
Step-by-step explanation:
Put the extra half rectangle in the empty space. It will end up being a perfect rectangle, then you did the area like you usually do..:
22 x 7.5.
=165
Good luck, hope i helped
I think the answer is the second one. A reflection over the x-axis and the a 90° counterclockwise rotation about the origin.
