Q1: Payments of $ 670 are being made at the end of each month for 5 years at an interest of 8% compounded monthly. Calculate the Present Value.

Answers

Answer:

$50,281.04

Step-by-step explanation:

5 years is equivalent to (5 × 12) = 60 months

Now, the first payment $670 is compounded for 60 months at the rate of $(8)/(12) = 0.667$ % monthly interest.

So, it will become $670(1 + (0.667)/(100))^(60) = 670(1.0067)^(60)$ .

Similarly the second payment of $670 will become $670(1.0067)^(59)$

Therefore, in this way after 60 months i.e. 5 years the total sum will be

= $670 + 670(1.0067)^(1) + 670(1.0067)^(2) + 670(1.0067)^(3) + ........ + 670(1.0067)^(59) + 670(1.0067)^(60)$

= $670[1 + (1.0067) + (1.0067)^(2) + (1.0067)^(3) + ....... + (1.0067)^(59) + (1.0067)^(60) ]$

= $670[1 * ((1.0067)^(61) - 1 )/(1.0067 - 1) ]$

= $50,281.04 (Answer)

{Since, the sum of the G.P. series $1 + r + r^(2) + r^(3) + .......... + r^(n) = 1 * (r^(n + 1) -1)/(r - 1)$ }

Payment of $ 670 with interest every month 8%

Then the payment is made for 5 years

If this year is the fifth year, the total payment is

($ 670 + 8%) x 60 months (1 Year 12 Months, 12 Months multiplied by 5)

($ 670 + $ 53.6 (monthly interest)) x 60

$ 723.6 x 60 = $ 43,416

So, the current value is $ 43,416

2 Ways to Calculate Loan Interest

Flat flowers

To make it easier for you to illustrate this flat interest calculation, the following is an example of the case: Mr. A applied for an unsecured loan of 240 million dollars with a repayment period of 12 months and a loan interest of 10% annually. This is an installment that must be paid by Mr. A every month.

Amount of loan: 240 million

Interest per year: 10%

Duration: 12 months

Principal installments:

$ 240 million: 12 months = $ 20 million / month

Flower:

($ 240 million X 10%): 12 months = $ 2 million

Installments every month:

$ 20 million + $ 2 million = $ 22 million

Effective interest

Thus is the illustration: Mr. B applied for a loan of $ 240 million. How many installments must be paid each month:

To calculate the interest the formula is: PL x i x (30/360)

PL: principal loan balance from the previous month

i: annual interest rates

30: number of days in a month

360: number of days in a year

Principal loan: $ 240 million

Interest: 10% per year

Credit period: 24 months

Month 1 installments:

= $ 240 million X 10% X (30 days / 360 days)

= $ 2 million

Principal installments plus interest in month 1 = $ 10 million + $ 2 million = $ 12 million.

Month installments 2:

= $ 230 million X 10% X (30 days / 360 days)

= $ 1,191,666.67

Skipper follows a path along the grid shown, always moving either up orto the right. How many paths from A to C do not pass through B?

Answers

We can use complementary counting. First we can count ALL the ways we can get from A to C. Then we can count the ways we can get from A to C, where we DO pass through B. Then we do the total minus the number of ways we DO pass through B.

Number of TOTAL ways from A to C.
First we can imagine fake, dotted lines around the top left and bottom right "corners" so we can make a complete square.
Once we have this "complete" square with the dotted line corners, we can easily find the number of paths from A to C. It is just $(8!)/(4!*4!)$ = 70. If you don't know how this was derived, just comment.
HOWEVER, of the 70 paths we just counted, 2 of them are not possible using the original picture. Remember those dotted corners we drew? We cannot create paths using those corners; they were just there so we could use a formula. So, we actually have 70-2 = 68 total paths.

Now we find the number of paths from A to C that DO pass through B.
Well, first we have to find the number of paths from A to B and then from B to C. This will guarantee we move through B. From A to B, there is $(4!)/(2!*2!) =6$ ways. From B to C, there is also $(4!)/(2!*2!) =6$ ways. 6*6 = 36

Jessica was solving an equation. After she finished simplifying, her result was 0=2. This result confused her. Explain to Jessica what her result means. Explain your reasoning thoroughly.

Answers

It means that the equations are not true. The straight lines are always parallel to the X-axis in all cases Therefore, the line doesn't cut the X-axis. This means that: there is no solution to the equation

Jessica's result means that any value of x (or any variable she used) would not be a solution to the equation. When something like 0 = 2 comes up, they answer is no solution.

For Your Information:

If you get 2=2 or 0=0 or anything like that, the solutions are all real numbers. Any value of x (or any variable used) will be a solution to the equation.

Please comment to let me know you understand. I hope this was helpful!

Sal is building a robot, if he puts a sphere on top of a cylinder. What would happen?

Answers

the sphere would fall over or be unbalanced on the cylinder, it doesn't have a flat surface where it can be balanced.

(unless you use glue or stick the sphere onto it :P)

something would have to hold the sphere in place or it would roll off the cylinder, but if it was in place it could be the head of the body.
