## Solution to QOTD 5/7/2020

To find the solutions to this, we need to look at the original table of values that is given: for each input (x), what is the relationship to the output (y)?

The table shows that for every hour worked, Kelli earns \$15.00. So, the more hours she works, the more money she will make. Therefore, the function is increasing. Because the rate that Kelli is paid is a constant, the function is linear. And if Kelli works zero hours, she will make zero dollars, so the y-intercept will be (0,0).

## Solution to QOTD 5/6/2020

To solve this, we need to find the measures of the sides of the triangle, using the distance formula. The distance formula is .

So our solution is scalene, because no two sides are congruent.

## Solution to QOTD 5/5/2020

In order for a relation to be a function, each input (x) must have a unique output (y). A vertical line test can be used when a graph is presented to see if the relation is a function; if a vertical line is dropped through the function and passes through more than one point, the relation is NOT a function.

For this problem, A and E are NOT functions. In example A, the letter C maps to two different values, and in example E, when a vertical line is dropped through the function, the line passes through more than one point.  Therefore, the functions are B, C, and D,

## Solution to QOTD 5/4/2020

To solve this, we will need to use the formulas for diameter and circumference.

First, with the radius, we can find the diameter of the circle.

D = 2r, so D = 8 inches.

Next, we can find the circumference of the entire circle.

Now, to find the measure of arc ADB, note that the angle measure is 120*. The total degree measure for a circle is 360*, so the arc is 1/3 of the circle. Therefore, the measure of the arc is

## Solution to QOTD 5/1/2020

For this, we need to be sure to get all of our terms together on one side of the equation, and then use our factoring skills to find the solutions.

First, move all of the terms to the left side of the equation:

Combine like terms:

Now we can factor, to find our solutions:

So our solutions are B and D.
