A catapult launches a boulder with an upward velocity of 92 m/s. the height of the boulder, h, in meters after t seconds is give

omeli [17]

Check the picture below.

$\bf \textit{vertex of a vertical parabola, using coefficients}
\\\\
h=\stackrel{\stackrel{a}{\downarrow }}{-5}t^2\stackrel{\stackrel{b}{\downarrow }}{+92}t\stackrel{\stackrel{c}{\downarrow }}{+16}
\qquad \qquad 
\left(-\cfrac{ b}{2 a}~~~~ ,~~~~ c-\cfrac{ b^2}{4 a}\right)$

$\bf \left( -\cfrac{92}{2(-5)}~~,~~16-\cfrac{92^2}{4(-5)} \right)\implies \left(\cfrac{46}{5}~~,~~16+\cfrac{2116}{5} \right)
\\\\\\
\left(\cfrac{46}{5}~~,~~\cfrac{2196}{5} \right)\implies \left(\stackrel{\textit{how long it took}}{9\frac{1}{5}}~~,~~\stackrel{\textit{how high it went}}{439\frac{1}{5}} \right)$

Let S be the surface z^2+x^2=1 with -17<=y<=7. Find a parameteriztion of the surface using the polar coordinates transform

julsineya [31]

The parameterization is already given to you, you just need to determine the domain for each parameter. $z^2+x^2=1$ is a cylinder that lies on the $y$ -axis with radius 1. You need to take $0\le v\le2\pi$ to get the entire lateral face, and $-17\le u\le7$ .
