Enlist your parents help to find you a decent tutor, it is much better to meet face to face.
Formula for growth:
y = initial • (percent growth + 1)^time/frequency of growth
So, since initial population is 382
Percent growth is 0.007
The time is 30 years
And it goes it by .07% every 1 year,
y = 382 • (1.007)^30/1
y= 470.9203732 people
Since we can’t have 0.9 of a person, the population after 30 years will be 470 people.

Step-by-step explanation:
To answer this question, we need to find the force applied by the rope on the bucket at time
At
After seconds, the weight of the bucket is
Since the acceleration of the bucket is the force on the bucket by the rope is equal to the weight of the bucket.
If the upward direction is positive, the displacement after seconds is
Since the well is 80 ft deep, the time to pull out the bucket is
We are now ready to calculate the work done by the rope on the bucket.
Since the displacement and the force are in the same direction, we can write
Use and
