What we know here is that all 2500 shares together are worth 100 000 dollars in total. (it's 100 000.00 actually, but we can ignore the part after the point, as it's equal to 0).
This means that each of the shares is valid the whole sum divided by the number of shares, that is:
(first i divided both denominator and numerator by 100)
So each value is worth 40 dolars.

Answer:
a) 4.392317 mt
b) 9 seconds
c)
Step-by-step explanation:
We have
where t is given in seconds and t in meters.
<em>a)How far has the point traveled 21 seconds after it started moving?</em>
By replacing t=21 in our equation we get
<em>b)If the point has traveled 3.16993 meters, how many seconds have elapsed since it started moving?</em>
We need to find a t such that f(t) =3.16993.
This can be accomplished by using the definition of
<em>c)Write a function that determines the number of seconds that have elapsed since the particle started moving in terms of the distance (in meters) the particle has traveled.</em>
is given by the definition of log
