Potato is launched vertically upward with an initial velocity of 100 ft/s from a potato gun at the top of an 85-foot-tall building. The distance in feet that
the potato travels from the ground after t seconds is given by
s(t) = -16t²+100t+85
a. Find the velocity of the potato after 0.5s and 5.75s.
b. Determine when the potato reaches its maximum height.
c. Find the acceleration of the potato at 0.5s and 1.5s.
d. Determine how long the potato is in the air.

The fraction of defective integrated circuits produced in a photolithography process is being studied. a random sample of 300 circuits is tested, revealing 17 defectives. (a) calculate a 95% two-sided confidence interval on the fraction of defective circuits produced by this particular tool. round the answers to 4 decimal places. less-than-or-equal-to p less-than-or-equal-to (b) calculate a 95% upper confidence bound on the fraction of defective circuits. round the answer to 4 decimal places. p less-than-or-equal-to
