Answer:

480 minutes

Step-by-step explanation:

We can write this relationship as y=0.11x+18 and then solve for x when y=70.80:

y=0.11x+18\\\\70.80=0.11x+18\\\\52.80=0.11x\\\\480=x

Therefore, you spent 480 minutes talking.

Use the power reducing formula to rewrite the expression in therms of first powers of hte cosines of ultiple angles 3cos^4x.
Oxana [17]

The particular identity you want to use is

\cos^2x=\dfrac{1+\cos(2x)}2

Then

3\cos^4x=3(\cos^2x)^2=3\left(\dfrac{1+\cos(2x)}2\right)^2=\dfrac34(1+\cos(2x))^2

Expand the binomial to get

3\cos^4x=\dfrac34\left(1+2\cos(2x)+\cos^2(2x)\right)

Use the identity again to write

\cos^2(2x)=\dfrac{1+\cos(4x)}2

and so

3\cos^4x=\dfrac34\left(1+2\cos(2x)+\dfrac{1+\cos(4x)}2\right)

3\cos^4x=\dfrac38\left(3+4\cos(2x)+\cos(4x)\right)
