m - slope

b - y-intercept

Miriam is setting up a fishing game in a kiddie pool for her niece's birthday party. The pool has a circular base with a diamete

AURORKA [14]

Answer:

4.7 feet³ of water

Step-by-step explanation:

Diameter of 4 feet

Radius = 2 feet

Height = 0.75 feet

Formula for Volume = 2· $\pi$ ·radius·height

But she only wants to fill half, so divide by 2, cancels the 2 in the formula for volume, giving us: $\pi$ ·radius·height

$\pi$ ·2·0.75 = 4.71 feet³

Which relation represents a function?

Airida [17]

<h3>Answer: Choice C</h3><h3>{ (-2,2), (0,2), (7,2), (11,2) }</h3>

Here we don't have any repeated x values.

In choice A, x = 2 repeats. In other words, x = 2 leads to multiple y outputs. So this is not a function. Choices B and D are similar stories. A function is only possible if every x leads to exactly one y value only. The graph must pass the vertical line test.

Side note: the y values can repeat, but the function won't be one-to-one.
