3. Mason, standing just outside his apartment building, throws a baseball upward from an initial height of 5 feet above ground level at an initial velocity of 90 ft/sec. The height of the baseball in terms of elapsed time is a quadratic relationship. The generalized equation is f(x) = –16x2 + v0x + h0, where v0 represents initial velocity and h0 represents initial height. Bill, on his third floor balcony 40 feet above ground level, launches his drone helicopter that ascends at a constant rate of 25 ft/sec. If Mason throws the baseball at the same time that Bill begins the ascent flight with his helicopter, formulate a system of equations to determine at what elapsed time(s) and height(s) the baseball would possibly strike the helicopter.

step-by-step explanation:

square prism looks like nothing like that

triangular prism has a rectangular base instead of a square base

tetrahedron has a triangular base

jacob, non hispanic white male. 30 years old.

probability that jacob lives to be 30 years old. 

since the given probabilities are probabilities of dying, i think we simply subtract it from 1 to get the probability of living. we will use the probability of non hispanic white male.

                                          probability of living to be 30 y.o.

29 - 30 : 1 - 0.001477 = 0.998523

30 - 31 : 1 - 0.001503 = 0.998497
