Its volume is decreasing at a rate of 100 cm³ /hr. How fast is the radius of the snowball decreasing when the radius is 25 cm? Note: Be sure to include the appropriate units in your response. Recall that the volume, V, of a sphere of radius r is given by V = ar. x² + 1 12. Let f(x) Show sufficient work in determining ... (a) the intervals over which f is increasing, the intervals over which f is decreasing, and any local extrema. Be sure to indicate whether an extremum is a maximum or a minimum. (b) the intervals over which the graph of f is concave up, those over which it is concave down, and any inflection points. 13. Find the absolute maximum obtained by s(t) = 2t3 – 3t² – 36t +5 on the interval [0,4]. You must show sufficient work for credit here. II
