It would appear yes it is B !! Good job
Answer:
Step-by-step explanation:
The length has been reduced to 6 inches from 18 inches.
That means the length has been reduced to 6/18 = 1/3 of its original size.
So the width must be reduced to 1/3 * 10 which is roughly 3.333 inches.
It doesn't look like any of them are right. i don't know how to make it right from the answers given.
Answer:
Cos²(45°—A) + cos²(45°+A)
= [2 cos²(45°—A) + 2 cos²(45°+A)] /2
= [{2 cos²(45°—A)—1} + {2 cos²(45°+A)—1} + 2] /2
= [cos2(45°—A)+cos2(45°+A)+2]/2
= [cos(90°—2A)+cos(90°+2A)+2]/2
= (sin2A—sin2A+2)/2
= 2/2
= 1
Answer: C, 3/4 And it's decimal form is 0.75
Step-by-step explanation:
The slope is the change in Y over the change in X.
Find 2 points on the line that cross X and Y that are easy to tell what numbers they are.
First point( 0,-4)
Second point (8,0)
The change in Y would be 0 - -4 = 0+4 = 4
The change in X would be 8 -0 = 8
The slope is 4 / 8 which reduces to 1/2
The answer is C.
