Answer:
Step-by-step explanation:
The volume of a sphere is
We are told our volume is 500pi/3, so we fill that in and solve for r:
Start by multiplying both sides by 3 over 4 pi:
Simplifying gives us
Take the cubed root of both sides to get that
r = 5
I think your best answer is a pasture that is 75 feet by 150 feet, which will give you 11,250 sq ft of pasture
The correct axis of symmetry is x = -1.
Explanation:
Our equation is
.
This is in vertex form, which is
y = a(x-h)² + k, where (h, k) is the vertex.
In our equation, h corresponds with -1 and k corresponds with -3, making the vertex (-1, -3).
The axis of symmetry is the x-coordinate of the vertex; this makes the axis of symmetry for this equation x = -1.
3b because b^2-4= 1/b. So 2/1/b= 2b b+2b = 3b
Answer:
10.3cm
Step-by-step explanation:
h=A
b=131.84
12.8≈10.3cm
