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:
UW = 5
Step-by-step explanation:
use the altitude rule and set up a proportion:
4/UW = UW/6.25
cross-multiply:
UW² = 25
UW = 
UW = 5
Answer:
(-2, -5)
Step-by-step explanation:
in a rectangle there will be 4 different numbers. Each number will have 2 spots. 2 numbers will have 2 x spots, and 2 numbers will have 2 y spots. we notice that our numbers are -2, -5, 3, and 4.
we see that -2 and 3 are our x values, and -5 and 4 are our y values.
-2 and -5 are the 2 numbers that have not been repeated, so the last corner's coordinates are (-2,-5)
Answer:
Meters
Step-by-step explanation:
Meter is the standard unit of length in SI system and is normally used to measure houses and fields, therefore it is appropriate unit of measure for the dimensions of the playground.
A meter has 100 centimeters which is fairly small unit and cannot be used for dimensions of playground.
Similarly a Kilometer has 1000 meters and is used to measure long distances from one place to other which also makes it inappropriate unit for dimension of playground.
Hope that clarifies the answer.
