Answer:
Step-by-step explanation:
It can be helpful to actually see the graph. For 0 ≤ θ ≤ π, a circle is developed above the x-axis, symmetrical about the y-axis (θ=π/2). For π ≤ θ ≤ 2π, the same circle is traced again in the same direction (CCW), as values of r are negative for those angles.
The circle has a radius of 2.5, centered at (0, 2.5), so the diameter is 5 units. The length of the diameter is the farthest distance between any two points on a circle.
For 1. The bike is going 24 miles in 3 hours. To figure out how many miles it went in 1 hour you divide 24/3 which is 8 miles. If the bike went 8 miles per hour then you may now multiply it by 10 to find the total mileage in 10 hours. 10x8=80

Answer:
slope is undefined
Step-by-step explanation:
Calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (- 3, - 1) and (x₂, y₂ ) = (- 3, 3)
m = 
= 
Since division by zero is undefined, then the slope is undefined.
This indicates the line is vertical and parallel to the y- axis
