Two rockets are launched from the ground at the same time. the height of rocket a in feet is modeled by

h(t)=-16t^2 + 128t

where t is the time in seconds after the launch the height of rocket b in feet is shown in the graph.

how do the maximum heights of the rockets compare?

a. rocket a goes about 130 ft higher than rocket b

b. rocket a goes about 148 ft higher than rocket b

c. rocket b goes about 16 ft higher than rocket a

d. rocket b goes about 46 ft higher than rocket a

50 ! pls ! 12.  building codes regulate the steepness of stairs. homes must have steps that are at least 13 inches wide for each 8 inches that they rise.

a. discuss how to find the slope of the stairs.
b. describe how changing the width or height affects the steepness of the stairs.

Which equation represents the function on the graph?

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
