Answer:
a) he rate of change of the volume of a snowball (due to melting) is proportional to the square of the volume at time t. Initially, the snowball has a volume of 900 cm3
and V(0) = 900
where A is a real constant, it appears because it says that the change i volume (dV/dt) is "proportional" to
. Furthermore, we should assume that A is a negative number, because the volume of the snowball will decrease as the time pasese by.
(b) For an insect moving along some path, the velocity at time t is proportional to the square root of its position.

Here again appears a constant B for the "proportional" part. And i wrote the velocity as
"the rate of change of the position with respect to te time".

Changing improper fractions to mixed
form or mixed numbers is a very simple thing. You just have to follow the following:
Then write
Let us have 25/8.
<span><span>
1.
</span><span>Divide the numerator (top
number) by the denominator (number below
the bar). </span></span>
Simply divide 25 by 8.
25 ÷ 8 = n
We can have 3 and 1 as a remainder. So, the
answer will be 3 and 1/8.

2.
</span> <span>Write down the whole number answer.
Since we have 3 as the whole number answer,
write it down. And;</span></span>
<span><span>
3.
</span><span> Write down any remainder above the denominator,
like this:</span></span>
3 and 1 (remainder) over 8
(denominator of the given improper fraction).
That is, 3 1/8
0.72 as a fraction is 18/25.
