Question

2) Graph the quadratic function. Specify the vertex, axis of symmetry, maximum or minimum value, and intercepts.
s = 1 + 3t - 10t 2

3) The total surface area of a right circular cylinder is 18 in. 2 Express the volume as a function of the radius.

4) Suppose that the height of an object shot straight up is given by h = 576t - 16t 2 . (Here h is in feet and t is in seconds.) Find the maximum height.

5) Six hundred feet of fencing is available for a rectangular pasture alongside a river, the river serving as one side of the rectangle (so only three sides require fencing). Find the dimensions yielding the greatest area.

Explanation / Answer

1. Points are (0,18000), (5,2000)

slope=-16000/5=-3200

y=mx + b

V(t)=-3200t + 18000

Correct option is the third one .
