The artist needs 180.5 square inches of material to create the kite.

Step-by-step explanation:

Step 1; The area of a kite is calculated by multiplying $\frac{1}{2}$ with the product of the diagonal lengths. Assume p is the diagonal length from the left to the right side and q is the diagonal length from the top to bottom.

p = 9.5 inches + 9.5 inches = 19 inches.

q = 7 inches + 12 inches = 19 inches.

Step 2; Area of the given kite is found using p and q by the following method;

Area of the kite = $\frac{1}{2}$ × (19 × 19) = 180.5 square inches.

So the $4^{th}$ option is the amount of material she requires.

What is the range of the function below in set builder notation? y=|x-3|

Kisachek [45]

Answer: $\{y | \ y \in \mathbb{R}, \ y \ge 0\}$

This translates to "y is any real number such that it is 0 or larger".

The reasoning is that the result of any absolute value function is either 0 or positive. In other words, we'll never get a negative result of an absolute value function. This is due to how absolute value represents distance. Negative distance does not make sense.

So if y = |x-3| then y = 0 is the smallest output possible. We could have any positive output we want.

In terms of a graph (see below), the V shape is at the lowest point (3,0). The y coordinate is all we care about in terms of finding the range. So we see the lowest y value is y = 0.
