Answer:
A. 1
B. -10
Step-by-step explanation:
Solution:
1. Cost of a new Violin that is bought by the musician = $ 2900
Monthly interest charge = 3.35 %
If you will find the compound interest or simple interest for a month, they both will be same for a month.
Simple interest =
Interest paid at the end of first month = $ 97.15
2. Loan Amount = $ 3,500
Annual interest = 8 %
Time period = 2 years= 24 months
As , we have to find the total payback for two years, at 8% annual interest with monthly payments .we will use the formula of Amount in terms of compound interest here.
Formula for Amount
Amount= ![Principal (1 +\frac{Rate}{100})^{time}]](https://tex.z-dn.net/?f=Principal%20%281%20%2B%5Cfrac%7BRate%7D%7B100%7D%29%5E%7Btime%7D%5D)
![=3500 \times [(1+\frac{8}{1200})^{24}]\\\\ = 3500 \times [(1.0066)^{24}]\\\\= 3500 \times 1.1710 \\\\ =4098.58](https://tex.z-dn.net/?f=%3D3500%20%5Ctimes%20%5B%281%2B%5Cfrac%7B8%7D%7B1200%7D%29%5E%7B24%7D%5D%5C%5C%5C%5C%20%3D%203500%20%5Ctimes%20%5B%281.0066%29%5E%7B24%7D%5D%5C%5C%5C%5C%3D%203500%20%5Ctimes%20%201.1710%20%5C%5C%5C%5C%20%3D4098.58)
Total payback after 2 years = $ 4098.58
Answer:
880
Step-by-step explanation:
the train travels=220km in 4 hours
therefore, multiply 220 and 4
=220 x 4 = 880
so, the train travels 880 km in 9 hours
HAVE A GREAT DAY!
Answer:
3n-1+8n+5
3n+8n-1+5
11n+4
Let me know if this helps!
Remark
The way this is written I would assume that it means 4*f(x) = x. That may not be entirely the correct assumption to be made.
Step One
Replace f(x) by 4f(x)
4*f(x) = x
Step two
Divide both steps by 4
f(x) = x/4 or (1/4)x
The slope is now 1/4
Discussion
A is incorrect.
The slope has been changed.
B is incorrect
The slope has been changed to 1/4 and the y intercept is still 0
C looks to be the right answer.
D The y intercept is still zero.
Comment
The question is a little hard to interpret. I've read it literally. That means that I have taken the question to mean that only f(x) was altered. If however, the right side was multiplied by 4 as well (as should be done), then the answer is A same slope same intercept. That's because the 4s on the left and right cancel, and the original equation results. I'm going to pick C but don't be surprised if it is A
C <<<<<answer
