Answer:
90 Test
Step-by-step explanation:
so if you do 36/4 that means 9 if the rate is constant then you do 9 x 10 = 90

The volume of the <em>oblate</em> spheroid is approximately equal to 75.398 cubic feet.
<h3>What is the volume of an oblate spheroid?</h3>
In this problem we have the shape of an ellipse centered at origin, whose vertex form is shown below:
x² / a² + y² / b² = 1 (1)
Where a, b are the lengths of the semiaxes, in feet.
An <em>oblate</em> spheroid is generated by revolving half of the ellipse about the y-axis. <em>Oblate</em> spheroids are a kind of ellipse:
x² / a² + y² / b² + z² / a² = 1 (2)
Where a, b, c are the lengths of the semiaxes, in feet.
And the volume of the <em>oblate</em> spheroid is:
V = (4 / 3) · π · a² · b (3)
If we know that a = 3 ft, b = 2 ft, then the volume of the oblate spheroid is:
V = (4 / 3) · π · (3 ft)² · (2 ft)
V ≈ 75.398 ft³
The volume of the <em>oblate</em> spheroid is approximately equal to 75.398 cubic feet.

Answer:
where −5 ≤ x ≤ 3
Step-by-step explanation:
The given function is
.
We want to select the option that describes all the solutions to the parabola.
The domain of the parabola is −5 ≤ x ≤ 3.
This means that any x=a on −5 ≤ x ≤ 3 that satisfies (a,f(a)), is a solution.
This can be rewritten as ![(a,-a^2-2a+8)](https://tex.z-dn.net/?f=%28a%2C-a%5E2-2a%2B8%29)
Therefore for x belonging to −5 ≤ x ≤ 3, all solutions are given by:
where −5 ≤ x ≤ 3.
