Answer:
If the 1.4% rate of interest is the weekly rate of interest, Then, total first week interest = 1.4(d - w)/100 = 0.014(d - w)
But if the 1.4% rate of interest is a yearly rate of interest compounded weekly, then her total first week interest = 7(d - w)/2600 = 0.00269 (d - w)
Step-by-step explanation:
The interest, I = PRT
P = initial amount of dollars in account = (deposit - withdrawal) = (d - w)
R = rate of interest = 1.4% = 0.014/week
T = time = 1 week
If the 1.4% rate of interest is the weekly rate of interest
I = PRT = (d - w) × 0.014 × 1 = 0.014(d - w)
But if the 1.4% rate of interest is a yearly rate if interest compounded weekly,
P = initial amount of dollars in account = (deposit - withdrawal) = (d - w)
R = rate of interest = 1.4% = 0.014/year
T = time = 1 week = (1/52) years
I = PRT = (d - w) × 0.014 × (1/52) = 7(d - w)/2600 = 0.00269 (d - w)

Answer:
Step-by-step explanation:
Because we have to rewrite this equation in the format 
, we have to divide, or factor to find basic terms,
Expanding the value of k(x), we have 
. We see that each term can be divisible by 4, so we can factor out 4 to get
Now, we have two different terms getting multiplied. We can separate the two to get 
Because we are multiplying 4 by the other term, this is represented by 
Now, we can just set f(x) and g(x) to these functions:
Now, just to make sure, we can plug a value into k(x) and the same value into f(g(x)). Plugging in 1, we have (2(1)+4)2 as 2(2+4), which is 2(6) = 12.
Plugging 1 into f(g(x)), we can evaluate g(1) first, to get 1 + 2 = 3. Now, f(3) = 4(3)= 12, which is the same for k(x).
