16.

h(t)    =    at^2

As  a   space   probe   descends    to  the surface of  Mars,   its distance    in  meters  above   the surface

can be  modeled by  the equation    above.  If  t   is  the time    in  seconds it  will    take    the probe   to

reach   the surface,    and it  takes   the probe   8   seconds to  descend the final   120 meters  to  the

surface,    what    is  the value   of  the deceleration    constant    a   ?

17.

        3 h –   j   =   7

2 h +   3j  =   1

Based   on  the system  of  equations   above,  what    is  the value   of  h   ?

18 .A   rectangular box has a   volume  of  24. If  the length  is  halved  and the height  is  tripled,    what

will    be  the new volume  of  the box?

19 .If  6e(e    +   3)  =   3e(2e   +   4)  +   5,  what    is  the value   of  e   ?

20 .Abeena  is  making  punch   for a   winter  party   in  a   punch   bowl    that    can hold    at  most    9   quarts.

She wants   to  get as  much    vitamin C   in  her punch   as  possible,   so  she is  using   only    orange

juice   and grape   juice.  She has 6   quarts  of  orange  juice,  which   has 2   grams   of  vitamin C

per quart,  and 7   quarts  of  grape   juice,  which   has 1   gram    of  vitamin C   per quart.  If  there   are

4   cups    in  a   quart,  what    is  the greatest    possible    amount  of  vitamin C,  in  grams,  that    Abeena

can have    in  one cup of  her punch?
