Answer:
3.07, 3.072, 3.7, 3.72 (the last option)
Step-by-step explanation:
Answer: a. (2.5, 300°) and (-2.5, 120°)
b. (4, 270°) and (-4, 90°)
<u>Step-by-step explanation:</u>
Polar coordinates are written as (r, θ) where
- r is the radius
- θ is the angle
In the first graph, the radius is 2.5 and the angle is 300° --> (2.5, 300°)
You can also list the radius as -2.5 at angle 120° --> (-2.5, 120°)
↓
(300 - 180)
In the second graph, the radius is 4 and the angle is 270° --> (4, 270°)
You can also list the radius as -4 at angle 90° --> (-4, 90°)
↓
(270 - 180)
Answer:
(0, -9) (1, -5)
Step-by-step explanation:
We know from the equation y = 4x -9, that the slope of the line is 4, and the point that the line crosses the y-intercept is at -9. So, your first point would be at (0, -9) and if you go one value over on the x-coordinate, that means the y-coordinate will go 4 up. So your final point will be (1, -5). The point could also be (2, -1), (3, 3), (4, 7), (5, 11), etc.
I Hope That This Helps! :)
