1. The volume of the sphere is increasing at the rate of 6cm^3/hr. At what rate is its surface are increasing (in cm^2/hr)
when the radius is 50cm.
2. A mango plantation has statistical records showing that uf 25 mango trees are planted, each tree yields 500 mangoes
(on the average) while the yield decreases about ten mangoes per tree for each additional tree planted. How many
trees should be planted for maximum total yield?
3. Find a point on the curve y=x^3 at which the tangent line is perpendicular to the line 3x+4y=4.
4. Find the area of the largest rectangle whose base is on the axis and whose upper two vertices lie on the curve y
12 - x2.
5. How many times does the graph of y=x^5-x will cross the x-axis? Defend your answer.
