2cm over 21 km =14 mm
I simplify and got C= 147km square
hope it helps
Answer:
(3, 1)
Step-by-step explanation:
Midpoint of the diameter is the center
Since endpoints are (9, 7) and (-3, -5)
Midpoint will be:
- ((9 - 3)/2, (7-5)/2) = (3, 1)
So the center is (3, 1)
As you can see, this is a negative slope. It goes down three and over four, as seen on the x and y intercepts. The answer kind of pops out at you.
To find the slope use the Rise over Run rule
It rises 2 units and runs 1 unit, so your slope is
2 or 2/1
To find the y-intercept just find where the line crosses the y-axis
it crosses at the -4 mark
Your slope is 2 and y-intercept is -4
Use the unit circle for the trigonometric identities
