Answer:
The unit circle centered at the origin in the Euclidean plane is defined by the equation:

Given an angle , there is a unique point P on the unit circle at an angle θ from the x-axis, and the x- and y-coordinates of P are:

Consequently, from the equation for the unit circle:
the Pythagorean identity.
Answer:
56
Step-by-step explanation:
Answer:
32 ft
Step-by-step explanation:
The perimeter is basically the area of the outside of a shape. To calculate this, you would add up all the sides together and get the answer.
8 + 8 + 8 + 8=32 or you can just do 8*4 which is also 32
So, the answer is 32
Answer:
B. 11/7
Step-by-step explanation:
Use rise over run, (y2 - y1) / (x2 - x1)
Plug in the points:
(y2 - y1) / (x2 - x1)
(-4 - 7) / (-5 - 2)
-11 / -7
= 11/7
If you mean that you want to solve the equation for v, then all you need to do is to multiply both sides by 3:
