A and b because the "product" is the answer to multiplication, and those are the only answers where 7 and n are being multiplied. Answer b is technically more correct than a is because the coefficient should come before the variable.
<span>Let Cos Y = 3/5
sin Y = 4/5
We know. cosYcosX+sinXsinY = cos (X-Y)
COS INVERSE( 3/5 COS X + 4/5 SIN X ) = COS INVERSE( cosYcosX+sinXsinY) = COS INVERSE(cos (X-Y) = X-Y
= X- cos inverse 3/5
= X - 57degrees</span>
Answer:
y-axis
Step-by-step explanation:
points are (x,y)
since the y-coordinate does not change, but the x-coordinate does, it rotates around the y-axis.
reflection just means it rotates 180 degrees (out of the paper, not around)
For area, just multiply the length x width
So therefore, multiply 36 inches x 48 inches and there you have it.
Now for the perimeter, it is a little different
You'd have to add the sides up together to get your answer for the perimeter.
So, 36 in + 36 in + 48 in + 48 in = answer
