Answer:
18.3
Step-by-step explanation:
384.3 divided by 21
1. Parabola's equation is y = a(x + b)^2 + c, where (b, c) is the vertex.
2. We have y = a(x - 3)^2 + 1
3. Take everything to the left side:
-a(x - 3)^2 + y - 1 = 0
That's the standard equation. Hope this helps! :)
When you cube something you times that number by itself 3 times.
Answer:
D. Reflect across the x-axis, then shift 4 units up
Step-by-step explanation:
In this case, reflecting across the x-axis just means going 4 units down. To go back up, go 4 units up.
The area of any circle is (pi) · (radius)² .
The radius is 1/2 of the diameter.
For your circle, the radius is 1/2 of 14 inches = 7 inches,
and the area is
(pi) · (7 inches)²
= (pi) · (49 square inches)
= 153.9 square inches (rounded)
