$\mbox{a rocket is shot straight into the air at an initial velocity of 96 feet/second. }$ $\mbox{the height of the rocket after }x\mbox{ seconds is represented by the formula }$ $h = 96x - 16x^{2}.\mbox{ what is the maximum height the rocket reaches? }$

to determine the unit cost your would divide the total cost by the number sold.

7 bagels for $4.41       $4.41/7 = $.63 each at fresh side

5 bagels for $3.60         $3.60/5 = $.72 each at value mart

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b

you,

mrb
