Astudent found the solution below for the given inequality.
|x-91 < -4
x-9 > 4 and x-9 < -4
x> 13 and x < 5
which of the following explains whether the student is correct?
the student is completely correct because the student correctly wrote and solved the compound inequality.
the student is partially correct because only one part of the compound inequality is written correctly.
the student is partially correct because the student should have written the statements using "or" instead of "and."
the student is completely incorrect because there is no solution to this inequality,

Angle mno is s rotated 180 degrees counterclockwise about the origin to form angle m’n’o’. which statement shows the measure of angle m’n’o’?

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
