Find two numbers a and b with a s b such that (3-2x-X?) dx has its largest value. and b =A flat circular plate has the shape of the region x"+ y- 1. The plate, including the boundary where x"+ y"=1, is heated so that the temperature at the point (x,y) is T(x,y) =x- + 3y- - 5x. Find the temperatures at the hottest and coldest points on the plate. 4 The hottest temperature on the plate is 29 degrees. (Type an integer or a simplified fraction.) The coldest temperature on the plate is degrees. (Type an integer or a simplified fraction.)
