Nicholas sent a chain letter to his friends, asking them to forward the letter to more friends. Every 12
1 answer:
Answer:
Step-by-step explanation:
The problem can be modeled by using the compound growth formula.
Given, Initial number of people who Nicholas sent the chain letter to=50
The growth rate, r =99%=0.99
Period of Growth,k =12 Weeks
Therefore, in any week (t) after Nicholas initially sent the mail, the number of people who receive the email is modeled by the function:

width = 35 units
Step-by-step explanation:
Let A, B, C and D be the corner of the pools.
Given:
The points of the corners are.
We need to find the dimension of the pools.
Solution:
Using distance formula of the two points.
----------(1)
For point AB
Substitute points A(30, 25) and B(30, 25) in above equation.
AB = 50 units
Similarly for point BC
Substitute points B(-20, 25) and C(30, -10) in equation 1.
BC = 35 units
Similarly for point DC
Substitute points D(-20, -10) and C(30, -10) in equation 1.
DC = 50 units
Similarly for segment AD
Substitute points A(-20, 25) and D(-20, -10) in equation 1.
AD = 35 units
Therefore, the dimension of the rectangular swimming pool are.
Length = 50 units
width = 35 units
