Step-by-step explanation:
Answer: Choice A) Graph crosses y axis at (0,-5), decreases from x = -10 to x = -2, constant from x = -2 to x = 10
--------------------------------------------------------
The statement "The graph crosses the y axis at (0,-5)" is a true statement because the red line crosses at -5 on the y axis. This allows us to rule out choice D. Choice C can be ruled out because the graph never increases. The graph would have to be moving uphill, as you read from left to right, to be increasing. Choice B is false because the junction point is at x = -2 and not x = 0.
Answer and Step-by-step explanation:
First, solve for the volume of the sphere, then solve for the height of the cone using the volume of the sphere (which is said to be equal to the volume of the cone) and the radius given.
<u>Volume formula of Sphere</u>
V =
<u>Substitute 1 in for r</u>
= Volume
<u>Finding the Height of a Cone</u>
Volume formula for Cone:
<u />
<u>Solve for </u><u><em>h</em></u>
Multiply both sides by 3, then divide by pi and r^2.
<u>Plug in the volume and the radius.</u>
<u>Simplify</u>
h ≈ 4
<u>4 is approximately the height.</u>
