The Answer would be B
it would be B because 8-2 is 6 and if you keep subtracting by 6 you will get ur answer and to get the first one you would just need to add 8 plus 6 to get 14
A is incorrect. The identity is for the Sin( A - B). It is not for the Cos(A - B)
B is closer, but NOT the answer. The sign in the middle is incorrect, for one thing. For another Cos(pi/2) = 0,, so the answer would be cos(theta) using this formula.
C The sign is correct in C. The problem is that it is the wrong formula for Cos(theta - pi/2). C should go
Cos(theta - pi/2) = cos(theta) cos(pi/2) + sin(theta)*sin(pi/2)
D. Looks like it's the correct answer. See the comment for C: The identity for C is actually correct for D.
Cos(theta)cos(pi/2) = 0 because cos(pi/2) =0
Sin(theta)*sin(pi/2) = Sin(theta) because Sin(pi/2) = 1
Answer D <<<<<< answer.
Use a calculator.
(23/13.8)-18=-16.333=(-16)-(1/3)
Answer:
B
Step-by-step explanation:
14p and 3p have the same variable
Answer:
Step-by-step explanation:
<u>Area Of A Cube
</u>
Suppose a cube with side length s, the area of one side is
Since the cube has 6 sides, the total area is
But if we have the area, we can solve the above formula for s to get
We have two different cubes with areas 1,200 square inches and 768 square inches. Let's compute their side lengths
The difference between them is
The side of the cube with area 1,200 square inches is 
longer then the side of the cube with area 768 square inches
