I’m stuck on this question. any help would be greatly appreciated
Mademuasel [1]

Using the Pythagorean theorem we get:

y^2+8^2=12^2.

Simplifying the above result we get:

y^2+64=144.

Subtracting 64 from the above equation we get:

\begin{gathered} y^2+64-64=144-64, \\ y^2=80. \end{gathered}

Therefore:

y=\sqrt{80}\approx8.9.

Answer:

y=8.9.

Determine the domain and range of the graph.
nirvana33 [79]

Answer:

Domain [-4,4]

Range [-2,2]

Step-by-step explanation:

The domain is the x-values of the graph and the range in the y-values. When writing domain and range it should be from least to greatest. So to find the domain find the lowest x-value on the graph and then the highest. Next, do the same for y-values. Finally, either surround each value with parentheses or bracket, the difference is that brackets mean that value is included, while parentheses mean that value is not actually on the graph.

In this case, the lowest x-value is -4 and the highest is 4, both values are included as signified by the closed circles, therefore the domain is [-4,4]. The lowest y value is -2 and the highest is 2, both are included, therefore the range is [-2,2].
