Literal equations: a literal equation is one consisting of all letters (or at least mostly letters). the latin word literalis means "of or belonging to letters or writing,"
giving the term literal equations its meaning. we can solve literal equations the same way we solve any other equation. we just need to be told which variable (letter) we
are solving for. to solve a -2 = 5 for a, we would add two to each side of the equation. to solve a r z for a, we would add r to each side of the equation. what would
the resulting solution be?

To find the extreme values of a function f(x.y) on a curve x-x(t), y y(t), treat f as a function of the single variable t and use the chain rule to find where df/dt is zero. in any other single-variable case, the extreme values of f are then found among the values at the critical points (points where df/dt is zero or fails to exist), and endpoints of the parameter domain. find the absolute maximum and minimum values of the following function on the given curves. use the parametric equations x=2cos t, y 2 sin t functions: curves: i) the semicircle x4,y20 i) the quarter circle x2+y-4, x20, y20 b, g(x,y)=xy

The mean finish time was 185.52 with a standard deviation of 0.327 minute. the winning car driven by chris finished in 185.13. the previous year race had a mean finish time of 110.3 with a standard deviation of 0.106. the winning car that year driven by karen finished in 110.13 minutes. find their respective z-scores. chris - z-score karen “- z-score
