Question

what is the length of the dominant line in the time graph below? l leave your answer in simplest radical form.

Answer 1

Let's first calculate the lenght of the side of the rectangle.

`l=\sqrt[]{8^2+5^2}=\sqrt[]{64+25}=\sqrt[]{89}`

so we get that the dotted line is:

`d=\sqrt[]{2^2+89}=\sqrt[]{93}`

so the answer is square root of 93
