Answer:

Step-by-step explanation:
The problem can be modeled by using the compound growth formula.
Given, Initial number P_0 of people who Nicholas sent the chain letter t=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:

I think b . sorry if it’s wrong
i think b because they charge daily so it would be how much money a day
Answer:
Let's solve for f.
fx=5x−3
Step 1: Divide both sides by x.
fx
x
=
5x−3
x
f=
5x−3
x
Let's solve for x.
fx=5x−3
Step 1: Add -5x to both sides.
fx+−5x=5x−3+−5x
fx−5x=−3
Step 2: Factor out variable x.
x(f−5)=−3
Step 3: Divide both sides by f-5.
x(f−5)
f−5
=
−3
f−5
x=
−3
f−5
Answer:
x=
−3
f−5

Its a. An enlargment on a scale of 3/1.
A + 4(a - 5) = 5
a + 4a - 20 = 5
5a = 5 + 20
5a = 25
a = 25/5
a = 5 <====
