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)

y-y1=m(x-x1)

y-(-9)=2(x-(-3))

y+9=2(x+3)

y=2x+6-9

y=2x-3

Ratio question: Paul and Luke share some money in the ratio 4:7. Paul gets £12 less than Luke. How much did they have in total?
Oksanka [162]
P/L=4/7  and P=L-12 so

(L-12)/L=4/7  multiply both sides by 7

(7L-84)/L=4  multiply both sides by L

7L-84=4L  subtract 4L from both sides

3L-84=0  add 84 to both sides

3L=84  divide both sides by 3

L=28, and since P=L-12

P=16

So they had 28+16 = £44 in total.
