Answer:
C: (4, 8)
Step-by-step explanation:
Rewrite the given equation x² - 8x = -y² + 16y - 44 in std. form:
x² - 8x + 16 - 16 + y² - 16y + 64 = 64 - 44, or
(x - 4)² + (y - 8)² = 64 - 44 + 16
Comparing this to (x - h)² + (y - k)² = 6²
we see that h = 4 and k = 8. The radius is 6. The center is at (4, 8) (Answer C).
Answer:
-5 and 3
Step-by-step explanation:
The roots of a quadratic function are also called the x intercepts.
The x intercepts are found by looking where where the quadratic equation crosses the x, or horizontal axis.
In this case, the quadratic equation crosses the x axis at (-5,0) and (3,0).
Therefore, our roots are -5 and 3
Answer:
12
Step-by-step explanation:
The equation is:
1/2x+4x+6-1/2x-2
Ok so you can cancel out 1/2x and 1/2x because 1/2x-1/2x=0
You are left with:
4x+4
If you plug in 2 for x
4(2)+4=12
I hope this helps :)

Answer:
900 sq ft
Step-by-step explanation:
The area of a trapezoid is (Base 1 + Base 2) * height/2. So to plug the numbers in...
(30+60)20/2
90*20/2
1800/2
900 sq ft
