Answer:
y = 130(24/13)^(x -10)
Step-by-step explanation:
The y-value changes by a factor of 240/130 = 24/13 for a unit change in the x-value. This means we can write the function as though it had an initial value of 130 and a growth factor of 24/13, translated 10 units to the right.
y = 130(24/13)^(x -10)
_____
<em>Additional comment</em>
This can also be written in the form ...
y = a·e^(kx)
where a=130·(24/13)^(-10) ≈ 0.28266, and k=ln(24/13) ≈ 0.61310
Answer:
A) -56
Step-by-step explanation:

Answer: The amount that Kristen would owe three months from now is $67.5
Step-by-step explanation:
The formula for determining simple interest is expressed as
I = PRT/100
Where
I represents interest paid on the loan.
P represents the principal or the current balance.
R represents interest rate
T represents the duration for which the account is overdue in years.
From the information given,
P = 1500
R = 18%
T = 3 months = 3/12 = 0.25 year
I = (1500 × 18 × 0.25)/100 = $67.5

Answer:
C. 5
Step-by-step explanation:
Point R divides the line segment PQ internally. The x-coordinate of the point which divides the line segment in ration m:n internally can be calculated as:

Here, x1 is the x-coordinate of 1st point, x2 is the x-coordinate of 2nd point, x is the x-coordinate of point dividing the segment. We have all the values except x2. Using the given values in above formula, we get:

Thus the x-coordinate of point Q will be 5
The x-coordinate of Q is 5.
