Answer:
D is the correct answer
Step-by-step explanation:
Given:
Unit base price: $435
Credit Card interest rate, i = 9.4% compounded monthly; i = 0.00783/month comp monthly
n = 1.5 years = 18 months
sales tax = 8.51%
First, determine the actual price of the unit by adding the sales tax to the base price of the unit:
$435 * (1 + 0.0851)
Actual price = $472.0185
So, the total amount paid by Brian should be higher than the actual price since he used his credit card. Use the formula from economics:
F = P (1+i)^n
F = $507.96
Therefore, the total amount paid by Brian is $507.96.

Y=mx+b
lines are parallels so m=2
y=2x+b
line passing through the point (4,2), so x=4 y=2
put these value in equation
2=2*4+b
2=8+b
b=2-8
b=-6
y=2x-6
Answer: y=2x-6
(verification on the picture)
The domain is the x intercept and the y intercept is the range
19-20 idk but ik the others

23.)-14.5
24.)7.838
Given:
The geometric sequence is:

To find:
The 9th term of the given geometric sequence.
Solution:
We have,

Here, the first term is:

The common ratio is:




The nth term of a geometric sequence is:

Where, a is the first term and r is the common ratio.
Substitute
to find the 9th term.




Therefore, the 9th term of the given geometric sequence is 5103.
