Find equations of the following. $ y = x^{2} - z^{2} $ , $ ({\color{red}9}, {\color{red}17}, {\color{red}8})$ (a) the tangent plane (b) the normal line to the given surface at the specified point. (Enter your answer in terms of t.)

78.59 is the mean

step-by-step explanation:

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

3 + 5 = 8

8 is smaller than 9 which is the third side.

hope this : )
