The radius is the distance from the center to any point. The distance from (2,1) to (0,1) is of course 2. The general formula for a circle with radius r and center (a,b) is
In our case we get

Answer: Choice D</h3>
The manager is correct because the number of children, 0.25(n + 244), is equivalent to the manager's expression, 0.25n + 61.
=======================================================
Explanation:
There are 244 men and n women giving 244+n total people, which is the same as n+244.
25% of this is 0.25(n+244)
Distribute that 0.25 through to each term inside the parenthesis
- 0.25 times n = 0.25n
- 0.25 times 244 = 61
There are 0.25n+61 children at this mall which is equivalent to 0.25(n+244)
In other words,
0.25(n+244) = 0.25n+61
is a true equation regardless of what value of n you pick. Both sides are identical.
Answer:
Step-by-step explanation:
Domain: I don't see any restrictions on the domain, although at some point y will become exceedingly large.
Range: -9 to infinity
Increasing Interval: x>2
Decreasing Interval: x <2
End behavior:
- as x ⇒∞, y⇒∞
These are the steps:
1. Find area of the two triangles.
2. Find area of the rectangle.
3. Add them up.
<u>Step 1: Find area of the two triangles:</u>
Formula : Area of triangle = 1/2 x base x height
Both triangles are identical.
Height = 5m
Base = 6 + 6 + 12 = 24
Area = 1/2 x 24 x 5 = 60 m²
<u>Step 2: Find the area of the rectangle:</u>
Formula : Area = Length x Width
Area = 12 x 7 = 84 m²
<u>Step 3: Find the total area:</u>
60 + 84 = 144 m²
Answer: 144 m²
. you multiply all of the values in the parentesys.
