The relationship is proportional. It goes through (0,0) and the slope is constant.
a. Practically speaking, you compute the differential in much the same way you compute a derivative via implicit differentiation, but you omit the variable with respect to which you are differentiating.
Aside: Compare this to what happens when you differentiate both sides with respect to some other independent parameter, say 
:
b. This is just a matter of plugging in 
and

Answer: Mom = 33 Son = 11
Step-by-step explanation:
A mother is three times as old as her son
Mom age =3x
AFTER 11 YEARS:
Son’s age =x+11
Mom’s age =3x+11
Also, she will be just twice his age
3x+11 = 2*(x+11)
or,3x+ 11 = 2x +22
or,3x-2x= 22–11
or, x=11
Son’s age = 11 years and mom’s age = 33 years
Answer:
Answer:
1/9
Step-by-step explanation:
4 people use all three facilities, then
16 - 4 = 12 people use the gym and the track and do not use the pool;
9 - 4 = 5 people use the pool and the track and do not use the gym;
19 - 4 = 15 people use the gym and the pool and do not use the track.
At least two facilities use 4 + 12 + 5 + 15 = 36 people, 4 of them use all three facilities. Thus, the probability that a randomly selected person which uses at least two facilities, uses all the facilities is 4/36=1/9
