Answer:

C) $-\frac{47}{49}$

Step-by-step explanation:

By the cos double angle formula, we know $\cos(2\theta)=2\cos^2\theta-1.$ Substituting $\cos \theta$ into the formula, we get

$\cos(2\theta)=2(-\frac{1}{7})^2-1\\~~~~~~~~~~=\frac{2}{49}-1\\~~~~~~~~~~=\boxed{-\frac{47}{49}}$ .

The answer is C.

Can you solve this ? Thanks

For #1
you would do
8 + 8 + 5 + 5 = 26
so they use 26 inches of ribbon

for #2
since there is 8 sides and each side is 3 feet we multiply
8 x 3 = 24
so the perimeter of her collage room is 24 feet

for #3
its cut off...
