Answer:
3/20 cake in 1 minute
Step-by-step explanation:
"3/4 of a cake in 5 minutes" is a verbal equation. We can divide both sides (that is, 3/4, 5 min) by 5 to determine the number of cakes I can bake in 1 minute:
3 5 min
-------- cake in -----------
4(5) 5
resulting in 3/20 cake in 1 minute.
The answer is: " <span>4 cos² Θ " .

Explanation:

(cos Θ − cos Θ)² + (cos Θ + cos Θ)²
= 0² + (cos Θ + cos Θ)² ;
= 0 + (2 cos Θ)² = (2 cos Θ)(2 cos Θ) ;
= 4 (cos Θ)² = 4 cos² Θ .

We know that sin (2x) = 2 sinxcosx.
So, sin (2x) + sin (x) - 2 becomes
2sin xcosx + sinx- 2.
Factor out sinx.
sinx(2cosx + 1 - 2)
sinx(2cosx - 1)
