Ok so our two variables will be:
x=age y=price
Our equation is:
y= -3000x + $25,635
The perpendicular slope is the negative reciprocal of the slope of the line it is perpendicular to. Therefore, the slope would be the negative reciprocal of -1/2 which would be 2.
From there, you plug in the coordinate into x and y and solve for b;
5 = 2 * -3 + b
5 = -6 + b
b = 11
Therefore the equation is;
y = 2x + 11
Answer:
a. csc²θ
Step-by-step explanation:
You can use the identities ...
1 +tan² = sec²
cot = cos/sin
sec = 1/cos
csc = 1/sin
___
Then the expression becomes ...
![\cot^2{\theta}(1+\tan^2{\theta})=\cot^2{\theta}\sec^2{\theta}=\dfrac{\cos^2{\theta}}{\sin^2{\theta}\cos^2{\theta}}=\dfrac{1}{\sin^2{\theta}}\\\\=\boxed{\csc^2{\theta}}](https://tex.z-dn.net/?f=%5Ccot%5E2%7B%5Ctheta%7D%281%2B%5Ctan%5E2%7B%5Ctheta%7D%29%3D%5Ccot%5E2%7B%5Ctheta%7D%5Csec%5E2%7B%5Ctheta%7D%3D%5Cdfrac%7B%5Ccos%5E2%7B%5Ctheta%7D%7D%7B%5Csin%5E2%7B%5Ctheta%7D%5Ccos%5E2%7B%5Ctheta%7D%7D%3D%5Cdfrac%7B1%7D%7B%5Csin%5E2%7B%5Ctheta%7D%7D%5C%5C%5C%5C%3D%5Cboxed%7B%5Ccsc%5E2%7B%5Ctheta%7D%7D)
