During  what    time    interval    (in sec)    is  the speed   increasing?

0   <   t   <   3

If      and y   =   3   when    x   =   1,  then

x   2    + y    2   =   10

y   =   x +     2

y   2   −   x   2   =   8

y   =   3x

A   solid   is  cut out of  a   sphere  of  radius  2   by  two parallel    planes  each    1
