A because the reflection is across the y axis
First In First Out.
FIFO intends to sell the first one that comes through the door first, and that item will be the oldest one in the inventory, so the old one gets sold first.
so it doesn't assume to sell the new one first.
2(cos2x - sin2x)
Step-by-step explanation:
Y = sin2x + cos2x
Differentiate wrt x
dy/dx = cos2x . 2 - sin2x . 2
= 2(cos2x - sin2x)
I'm not completely sure what you are asking, because your question did not make much sense, but the triangles are similar. The first triangle was doubled (or multiplied to a scale factor of 2) to get to the second triangle. So they are similar because one is twice as big as the other.
I hope this helped! If it didn't, please reply. If it did, please do not forget to mark it as the brainliest!
Answer:
59.5
Step-by-step explanation:
area of the triangle is (7 x 3)/2=21/2=10.5
area of the square 7x7=49
