Any number to the power of a negative integer will be 1 over that number with the absolute value of the power, so it looks like this:
![x^{-2} = \frac{-1}{x^{2}}](https://tex.z-dn.net/?f=%20x%5E%7B-2%7D%20%3D%20%5Cfrac%7B-1%7D%7Bx%5E%7B2%7D%7D%20)
Therefore, you just need to 8² which is 64, and then do 1 over that (1/64) because it's a negative power.
let's say that sin(θ) = x, then the cos(θ) which is twice the sine has to be 2x, therefore then
![\bf tan(\theta )=\cfrac{sin(\theta )}{cos(\theta )}~~ \begin{cases} sin(\theta )=x\\ cos(\theta )=2x \end{cases}\implies tan(\theta )=\cfrac{x}{2x}\implies tan(\theta )=\cfrac{1}{2}](https://tex.z-dn.net/?f=%5Cbf%20tan%28%5Ctheta%20%29%3D%5Ccfrac%7Bsin%28%5Ctheta%20%29%7D%7Bcos%28%5Ctheta%20%29%7D~~%20%5Cbegin%7Bcases%7D%20sin%28%5Ctheta%20%29%3Dx%5C%5C%20cos%28%5Ctheta%20%29%3D2x%20%5Cend%7Bcases%7D%5Cimplies%20tan%28%5Ctheta%20%29%3D%5Ccfrac%7Bx%7D%7B2x%7D%5Cimplies%20tan%28%5Ctheta%20%29%3D%5Ccfrac%7B1%7D%7B2%7D)
First we need to find 75% of $450, so 450x.75=337.5
to find the markup we have to add 450+337.5 to get $787.5.
Answer: the first diagram
Step-by-step explanation:
The shaded region of 2 rows is 40%
While the unshaded region on 3 rows is 60%
