In mathematics, a unit circle is a circle of unit radius—that is, a radius of 1. Frequently, especially in trigonometry, the unit circle is the circle of radius 1 centered at the origin (0, 0) in the Cartesian coordinate system in the Euclidean plane.
I would say D the other answers seem wrong
Perimeter = 56
Hypo = 25
So 56-25 = 31 (for two side)
for one side = 31/2 = 15.5
so area = 1/2 x base x height
The domain is (0,-5) and range is (0,-7) the y is the range and the x is the domain
Answer: From what I understand you want me to do 7*(-15)??? and the answer to that is -105.
Step-by-step explanation: All you have to do is 7*-15
