Use the power-reducing formulas to rewrite the expression in terms of first powers of the cosines of multiple angles.

This is the same question as 17042785 (the question number in the site URL), with the exception of using the other identity,

$\sin^2x=\dfrac{1-\cos(2x)}2$

We have

$2\sin^4(2x)=2(\sin^2(2x))^2=2\left(\dfrac{1-\cos(4x)}2\right)^2=\dfrac12(1-\cos(4x))^2$

Expand the binomial:

$2\sin^4(2x)=\dfrac12(1-2\cos(4x)+\cos^2(4x))$

Using the identity in the previous question,

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

we get

$\cos^2(4x)=\dfrac{1+\cos(8x)}2$

So,

$2\sin^4(2x)=\dfrac12\left(1-2\cos(4x)+\dfrac{1+\cos(8x)}2\right)$

$2\sin^4(2x)=\dfrac14\left(3-4\cos(4x)+\cos(8x)\right)$

If $5000 is invested at an interest rate of 3.396 compounded monthly for 10 years, what would be the balance in the account

saul85 [17]

Answer: D

Step-by-step explanation:

Months = 12 x 10 = 120months

100%+3.396%=103.396% / 100 = 1.03396

5000 X (1.03396)^120 = 275054.36

Find DE (trigonometry)<br> Show work pls

Ksju [112]

Answer:

Step-by-step explanation:

tan61=FD/24

FD=24tan61

tan19=DE/FD

DE=FDtan19, since FD=24tan61

DE=(24tan61)(tan19) (exact)

DE=14.9 units (rounded to nearst tenth)

Though they might round to 15 units...
