At the moment, I am a Graduate Assistant at LSU. This semester I am teaching College Trigonometry, and in the previous semester, I taught College Algebra. Before that, I worked as a Teaching Assistant at Nazarbayev University. The classes I taught there include: Calculus I, II, and III, Linear Algebra, Precalculus.

Ross has a laser sight for golf that gives him the straight line distance to any object he points the sight at. From an elevated tee block, he uses the sight and finds that the straight line distance to the green is 278 meters. He also determines that the angle of depression to the green is 52°. What is the height of the elevated tee block above the level of the green?
Options:a) 219mb) 305mc) 191md) 171m
Find the relative extrema of the following function of twovariables. f(x, y) = e^x^2 + y^2Find all critical point(s). Write your answer as a point, (x,y).Critical Point: (a, b) =(0,0) CorrectTest the critical point to determine what it is. You testcritical points as follows. Find the determinant function:D(x, y)=
