Check that the point (1,−1,3) lies on the given surface. Then, viewing the surface as a level surface for a function f(x, y,z), find a vector normal to the surface and an equation for the tangent plane to the surface at (1,−1,3). 2x2−3y2+2z2=17

The graph shows the function f(x) = (2.5)x was horizontally translated left by a value of h to get the function g(x) = (2.5)x–h.

Which of the following represents the length of a diagonal of this trapezoid?

Me with this assignment ! i only partially understand, so explain. also it's a work sample. at the championship bike race, steve and paula were fighting for first place. steve was 175 feet ahead of paula and had only 300 feet left to go. he was very tired and was going only 9 feet per second. paula was desperate to catch up and was going 15 feet per second. who won the bike race and by how far did she/he win?
