37. an object is shot straight up from the ground with an initial velocity of 112 ft/sec.

a) find the interval of time t during which the object is 160 feet above the ground or higher.

b) at what time does the object reach its highest point and what is the highest point reached by
the object?
note: the equations relating to the motion of gravity are y = -16tº + vt + y, and
v=-32t + vo where v, is the initial velocity and y, is the height with respect to the ground at
time t = 0. here, we assume that y = 0 at the ground level.

What is the product? (x2+3y+7) [yy+1)

Since opening night, attendance at play a has increased steadily, while attendance at play b first rose and then fell. equations modeling the daily attendance y at each play are shown below, where x is the number of days since opening night. on what day(s) was the attendance the same at both plays? what was the attendance? play a: y = 8x + 191 play b: y = -x^2 + 26x + 126 a. the attendance was never the same at both plays. b. the attendance was the same on day 5. the attendance was 231 at both plays on that day. c. the attendance was the same on day 13. the attendance was 295 at both plays on that day. d. the attendance was the same on days 5 and 13. the attendance at both plays on those days was 231 and 295 respectively.

Which of the following is the shape of a cross section of the figure shown below
