I believe the X-coordinate of the midpoint would be (0.5,-0.5)
Answer:
412.5 miles
Step-by-step explanation:
1) 2.75/0.5=5.5
2)5.5x75=412.5
it is -4
Step-by-step explanation:
if you do it From left to right it's -4
A = π(r²) --- r is radius
C = πd --- d is diameter
First, the circumference must be found. If the circumference is 15.7, plug it in.
15.7 = πd
We know what pi is.
15.7 = 3.14 (d)
Now, simply divide 3.14 by 15.7 to find the diameter (d). You get 5. Since the radius is half of the diameter, the radius is 2.5. Plug this into the area formula, and plug pi in, too.
A = 3.14(2.5²)
2.5 to the second power is 6.25.
A = 3.14(6.25)
Tada! Multiply, and you're left with 19.625!

Answer:
Step-by-step explanation:
The given expression is 
We want to find the value of h(-9).
We substitute r=-9 to obtain:
We multiply out to obtain:
We simplify the denominator to obtain:
This is the same as:
