Answer:
The diameter is 9.252 :)
Step-by-step explanation:
From the given diameter, get the radius. The perimeter of a semicircle is half the perimeter of a circle, but we excluded the base. So, the perimeter now is:
2πr+2r
Put the value of radius in the formula and get the answer wich is 9.252!
PLEASE MARK BRAINLIEST!!!
Ah, one of my FAVORITES!
1. Take 2 points, ill take (0, 0) and (4, 12)
2. Set them as "1" and "2" so (0, 0) be 1 and (4, 12) be 2.
3.

and insert the equations.
4. You get

which simplifies to

.
5.

=3
6. Slope = 3
Hope this helps ^^
Answer:
Step-by-step explanation:
True, this is not a function, and the reason for that is that two of the ordered pairs have the same x-coordinate (1).
The domain is the set of all input values shown; they are {-2, -1, 1}.
The domain is the set of all possible output values; they are {-2, 0, 2, 3}
Remark
Not many per square mile. Sounds like an ideal place to live.
Step One
Find the number of Square Miles.
Area = Height * Width
Area = 380 * 200
Area = 76,000 square miles.
Step Two
Find the Density
<u>Formula</u>
Density = Population / Square Miles
Population = 814,000 people
Square miles = 76000
Solve
Density = 814000/76000 = 10.7 people per square mile.
Remark
Isn't that incredible. It means if all the Area of South Dakota were given to the people living there, each family of 4 would get roughly 1/2 a square mile.
