20 is the answer.
15% of 50= 7.5
45% of 50= 22.5
22.5+7.5=30
50-30=20.

<em>Comment on percentages</em>
Of course, you know that 4.5% = 4.5/100 = 45/1000 = 0.045.

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
