A hemispherical water tank. shown below has a radius of 6 meters and is losing water. The area of the surface of the water is A=12pih-pih^2 square meters, where h is the depth, in meters, of the water in the tank. When h=3 meters, the depth of the water is decreasing at a rate of -1/2 meters per minute. At that instant, what is the rate at which the area of the water's surface area is decreasing with respect to time?
A thin observatory probe having the shape of a plate is probing a volcano in an xy −plane at a point P(x, y). The probe can only withstand a certain amount of temperature; thus, Represent the temperature as the function of x and y when the temperature calculated in degrees Celsius is inversely proportional to the square of its distance from theorigin.

A particle moves along a line. Its position x (in centimeters to the right of the origin) is a function of time t (in seconds) shown by the graph to the right. (a) identify value(s) of t which are critical numbers for the position function x(t) (b) identify values of t which correspond to inflection points on the graph of x(t) (d) identify a t-interval on which the velocity x 0 (t) is negative and the acceleration x 00(t) is positive. (e) identify a t-interval on which both the position x(t) and the velocity x 0 (t) are decreasing.
A tank that contains 20 gal of water in which 3 kg of salt has been dissolved completely is to be filled by a hose with water carrying 0.25 kg/gal of salt at a rate of 4gal/min. The mixture is then stirred and the solution isbeing pumped out at the same rate. Find the function of salt in the tank at any given time.
