The graph below

Step-by-step explanation:

We have a graph and an equation and are asked to create the graph.

how do you find the diagonal of a rectangle prism please step by step

Answers

Answer: How to find diagonal length of a rectangular prism?

Step-by-step explanation:To find the diagonal distance of a prism, you can use the formula: \displaystyle d = \sqrt{w^{2} + l^{2} + h^{2}}, where = height; = width, and = length. \displaystyle d = \sqrt{2^{2} + 8^{2} + 10^{2} } = \sqrt{4 + 64 + 100} = \sqrt{168} = \sqrt{4 * 42} = 2\sqrt{42}.
