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.

Step-by-step explanation:
The problem statement gives you the relationship between their speeds, and it gives you information you can use to find their total speed. You solve this by finding the total speed, then the proportion of that belonging to Bill.
The total speed is (120 mi)/(3 h) = 40 mi/h.
The speed ratio is ...
... Bill : Joe = 3 : 1
so the speed ratio Bill : Total is ...
... 3 : (3+1) = 3:4.
Bill's speed is (3/4)×(40 mi/h) = 30 mi/h.
Answer C cause I remember
Answer:
Step-by-step explanation:
Given
Shape: Trapezoid
Required
Determine the length of the second parallel side
The area of a trapezoid is:
Substitute values for Area, Height and Side1
Multiply both sides by 2
Divide both sides by 18
Hence;
<em>The length of the second parallel side is 17cm</em>
