Answer:

Step-by-step explanation:
To solve for the leg of the missing right triangle, one must use the Pythagorean theorem. The Pythagorean theorem states the following,

Where (a) and (b) are the sides adjacent to or next to the right angle. (c) is the side opposite the right angle. Substitute in the given values and solve for the unknown,

Substitute,

Simplify,

In my opinion, the correct answer among the choices listed above is option B. A sphere made up of many circular cross sections. When you cut through a plane at any angle or side, you will see that the plane made will always be a circle.
Answer:
- domain: [0, ∞)
- range: (-∞, ∞)
- not a function
Step-by-step explanation:
The arrows indicate the graph continues indefinitely in the direction indicated.
The domain is the horizontal extent, so is the interval from 0 to infinity, including 0.
The range is the vertical extent, so extends from negative infinity to positive infinity (all real numbers).
The graph does not pass the vertical line test: a vertical line intersects it in more than one place, so the relation is NOT a function.
