Solve the problem.Water is falling on a surface, wetting a circular area that is expanding at a rate of 3 mm2/s.  How fast is the radius of the wetted area expanding when the radius is 123 mm?  Round your answer to four decimal places.

Find any local extrema of the function and where they occur. y = x3 – 12x + 2Give an EXACT answer, no decimal approximations. If necessary, use the forward slash, /, for fractions.    Local Maximum: ( [xmax], [ymax] )Local Minimum: ( [xmin], [ymin] )

Evaluate dy/dt for the function at the point.x3ey – y3 ln x = 10 dx/dt = 1 x = 1 y = 2

Find the absolute extreme values of the function on the interval. f(x) = tan x,
