Suppose you want to purchase a $ 195000 house. If you put 20% down and finance the rest in a 15 year mortgage at an interest rate of 4%, what will your monthly payments be?
Monthly payment

Answers

Answer 1

The monthly payment on a principal of $156000 with interest rate of 4% over a time period of 15 years is $1153.91

Monthly Payment

The monthly payment is the amount paid per month to pay off the loan in the time period of the loan. When a loan is taken out it isn't only the principal amount, or the original amount loaned out, that needs to be repaid, but also the interest that accumulates.

The formula of monthly payment is given as;

A = P [r(1 + r)ⁿ] / [(1 + r)ⁿ - 1]

A =  Monthly paymentr = ratep = principaln = number of payment

The principal of the loan can be calculated as 20 % of 195000

20 / 100 = x / 195000

0.2 = x / 195000

x = 39000

The principal is 195000 - 39000 = 156000

The principal is 156000, rate is 4% and time is 15 year

Substituting the values into the formula

A = 156000[0.04(1 + 0.04)¹⁸⁰] / [(1 + 0.06)¹⁸⁰ - 1]

A = 1153.91

The monthly payment is $ 1,153.91

KADS, Incorporated has spent $490,000 on research to develop a new computer game. The firm is planning to spend $290,000 on a machine to produce the new game. Shipping and installation costs of the machine will be capitalized and depreciated using bonus depreciated; they total $59,000. The machine has an expected life of three years, a $84,000 estimated resale value, and falls under the MACRS seven-year class life. Revenue from the new game is expected to be $690,000 per year, with costs of $340,000 per year. The firm has a tax rate of 21 percent, has an opportunity cost of capital of 12 percent, and expects net working capital to increase by $145,000 at the beginning of the project. What will the cash flows for this project be? Note: Negative amounts should be indicated by a minus sign. Round your answers to 2 decimal places.

Year 0 1 2 3
FCF ___ ___ ___ ___

Answers

Answer:

To find the cash flows for this project, we need to calculate the net income for each year and then subtract any investments in net working capital and capital expenditures.

In year 0, the firm will incur the following expenses:

- Research and development costs: $490,000

- Cost of the machine: $290,000

- Shipping and installation costs: $59,000

- Increase in net working capital: $145,000

Total expenses in year 0: $490,000 + $290,000 + $59,000 + $145,000 = $984,000

The net income in year 0 is equal to the revenue minus the costs: $690,000 - $340,000 = $350,000.

Therefore, the cash flow in year 0 is:

FCF0 = $350,000 - $984,000 = -$634,000

In years 1, 2, and 3, the firm will incur the following expenses:

- Cost of goods sold: $340,000

- Depreciation: (This can be calculated using the MACRS depreciation schedule. For the first year, the depreciation will be 14.29% of the cost of the machine, or 0.1429 * $290,000 = $41,461. The depreciation in subsequent years can be calculated using the same method.)

- Increase in net working capital: $145,000

Total expenses in each of years 1, 2, and 3: $340,000 + Depreciation + $145,000

The net income in each of these years is equal to the revenue minus the costs: $690,000 - (Total expenses)

The cash flow in each of these years is equal to the net income minus any investments in net working capital and capital expenditures: Net income - Increase in net working capital - Depreciation

Substituting the appropriate values, we get:

Year 1: FCF1 = $690,000 - ($340,000 + $41,461 + $145,000) = $163,539

Year 2: FCF2 = $690,000 - ($340,000 + Depreciation + $145,000)

Year 3: FCF3 = $690,000 - ($340,000 + Depreciation + $145,000)

Note that the depreciation in years 2 and 3 can be calculated using the same method as in year 1.

So, the cash flows for this project are:

Year 0 1 2 3

FCF -$634,000 $163,539

400 square feet of carpet area for $240 is the best deal among the given option.

What is Area?

The measurement that expresses the size of a region on a plane or curved surface is called area. Surface area refers to the area of an open surface or the boundary of a three-dimensional object, whereas the area of a plane region or plane area refers to the area of a form or planar lamina. Area can be interpreted as the quantity of material with a specific thickness required to create a model of the shape or as the quantity of paint required to completely cover a surface in a single coat. It is the two-dimensional equivalent of the volume of a solid or the length of a curve, both of which are one-dimensional concepts (a three-dimensional concept).

Detailed explanation:

The carpets were sold for the following prices:

1) $67 for 100 square feet.

2) $130 for 200 square feet.

3) $240 for 400 square feet

4) $504 for 800 square feet.

Calculation:

For each of them, we would calculate the unit cost per square foot. It develops

1) The price per square foot is 67÷100 = $0.67

2) The price per square foot is 130÷200 = $0.65.

3) The price per square foot is 240÷400 = $0.6.

4) The price per square foot is 504÷800 = $0.63.

Comparing the unit costs per square foot the best deal costs $0.6 per square foot per unit, which is 400 square feet of carpet for $240.

400 square feet of carpet area for $240 is the best deal among the given option.

What do you mean by probability?

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

According to the given question:

Assume you have a fair coin, which means it will likely land tails up 50% of the time and heads up 50% of the time. Let's say you flip it three times, each time independently. What is the likelihood that it will land heads up first, followed by a tails up landing?

The solution is 1/8, or 12.5%.

coin flipped = 3 times.

probability of getting three heads = 0.125

Since, This probability explains the chances of landing three heads which is 0.125 which in terms of percentage is 12.5% .

So, The statement is If you flip 3 coins 5000 times, the percentage of time you get three heads will be very close 12.5%.

The mean s recorded by 27 candidates happened to be 64%. During inspection it was found that one candidate actually scored 74% s instead of 47% recorded in the result sheet. What will be the correct mean?

Answers

Step-by-step explanation:

the mean score is the sum of all scores divided by the number of scores.

64 = (s1+s2+s3+...+s26+s27)/27

64×27 = (s1+s2+s3+...+s26+s27)

1728 = (s1+s2+s3+...+s26+s27)

now, one of the scores changes from 47 to 74. that means the sum of all scores is increased by 74-47 = 27.

so, we get

1728 + 27 = (s1+s2+s3+...+s26+s27+27)

1755 = (s1+s2+s3+...+s26+s27+ 27)

we still have 27 scores, so for the updated mean we have to divide both sides by 27 again :

1755/27 = (s1+s2+s3+...+s26+s27+27)/27

65 = (s1+s2+s3+...+s26+s27+27)/27

the correct mean is therefore 65%.

A rock falls from a tower that is 352 feet high. As it is falling, its height is given by the formula h=352-16t^(2). How many seconds (in tenths ) will it take for the rock to hit the ground (h)=(0)?

Answers

The rock will take 10.25 seconds to hit the ground, as the amount determined by the formula h=352-16t^(2).

The given equation is h=352-16t^(2). This equation can be used to calculate the time it will take for a rock to hit the ground after it has been dropped from a tower that is 352 feet high. The equation states that the rock's height (h) is equal to 352 minus 16 times the square of the time (t). To find the time it will take for the rock to hit the ground (h=0), we can rearrange the equation to solve for t. The rearranged equation is t=sqrt((352-0)/16), which simplifies to t=10.25. This means that the rock will take 10.25 seconds to hit the ground. This can also be expressed in tenths of a second as 102.5, which is the same as 10.25 seconds.

assume the series can be integrated term by term. use this fact and the result from part a) to find the fourier cosine series of the function f(x)

Answers

To find the Fourier cosine series of the function f(x), we first need to find the Fourier coefficients of f(x).

The Fourier coefficients of f(x) are given by:

a0 = (2/L) * integral of f(x) from x=0 to x=L

an = (2/L) * integral of f(x) * cos(npix/L) from x=0 to x=L

bn = (2/L) * integral of f(x) * sin(npix/L) from x=0 to x=L

Using the result from part a) and the fact that the series can be integrated term by term, we can find the Fourier cosine series of f(x) as follows:

F(x) = a0/2 + sum from n=1 to infinity of an * cos(npix/L)

Therefore, the Fourier cosine series of the function f(x) is:

F(x) = (1/L) * integral of f(x) from x=0 to x=L + sum from n=1 to infinity of (2/L) * integral of f(x) * cos(npix/L) from x=0 to x=L

(use six equal subintervals.)

Answers

The upper and the lower estimates (in tons) for the total quantity q(6) of erupted materials after six seconds is 224 and 166 metric tons respectively.

The volcano is erupting and readings of the rate r(t) at which solid materials are spewed into the atmosphere are given in the table

Assuming that r(t) is increasing for all t in [0,6], a lower estimate is obtained by using left endpoints and an upper estimate is achieved by using right endpoints.  

Lower estimate:  r(0)(1)+r(1)(1)+r(2)(1)+r(3)(1)+r(4)(1)+r(5)(1)

                      = 2+12+20+36+44+52 = 166 metric tons

Upper estimate:  r(1)(1)+r(2)(1)+r(3)(1)+r(4)(1)+r(5)(1)+r(6)(1)

                      = 12+20+36+44+52+60 = 224 metric tons

Midpoint estimate:  r(1)(2)+r(3)(2)+r(5)(2)

                         = 24+72+104 = 200 metric tons

Therefore, the upper and the lower estimates (in tons) for the total quantity q(6) of erupted materials after six seconds is 224 and 166 metric tons respectively.

Answer:

x = 28 units

Step-by-step explanation:

As AP is parallel to CD (indicated by the arrows on the line segment), triangle APR is similar to triangle CDR.

In similar triangles, corresponding sides are always in the same ratio.

[tex]\implies \sf AP:CD=PR:DR=AR:CR[/tex]

Given

PR = 15 + 42 = 57DR = 42AR = 10 + xCR = x

Therefore:

[tex]\implies \sf PR:DR=AR:CR[/tex]

[tex]\implies \sf 57:42=10+x:x[/tex]

[tex]\implies \sf \dfrac{57}{42}=\dfrac{10+x}{x}[/tex]

[tex]\implies \sf 57x=42(10+x)[/tex]

[tex]\implies \sf 57x=420+42x[/tex]

[tex]\implies \sf 15x=420[/tex]

Let X1,82 be independent random variables representing lifetimes (in hours) of two key components of a device that fails when and only when both components fail. Say each Xi has an exponential distribution with mean 1000. Let Y1 = min(X1,X2) and Y2 = max(X1,X2), so that the space of Y1,Y2 is 0 < y1 < y2 <. (a) Find G(y1, y2) = P(Y1 = 71,Y2 = y2).

Answers

To find the probability that Y1 = 71 and Y2 = y2, we can write G(y1, y2) = P(Y1 = 71, Y2 = y2).

To find the probability that Y1 = 71 and Y2 = y2, we need to consider the possible values of X1 and X2 that could lead to these values of Y1 and Y2. The probability density functions (PDFs) of an exponential distribution with mean 1000 is f(x) = 1/1000 * e^(-x/1000). Therefore, the probability of this event is

P(X1 = 71, X2 = y2) = f(71) * f(y2) = 1/1000 * e^(-71/1000) * 1/1000 * e^(-y2/1000).

Another possibility is that X1 = y2 and X2 = 71. The probability of this event is

P(X1 = y2, X2 = 71) = f(y2) * f(71) = 1/1000 * e^(-y2/1000) * 1/1000 * e^(-71/1000).

Since these two events are mutually exclusive and exhaust all possible ways that Y1 can equal 71 and Y2 can equal y2, the probability of these events occurring is the sum of these probabilities. Therefore,

G(y1, y2) = P(Y1 = 71, Y2 = y2) = P(X1 = 71, X2 = y2) + P(X1 = y2, X2 = 71) = (1/1000 * e^(-71/1000) * 1/1000 * e^(-y2/1000)) + (1/1000 * e^(-y2/1000) * 1/1000 * e^(-71/1000)) = 2/1000^2 * e^(-(71 + y2)/1000).

Note that this expression is only valid when 0 < 71 < y2 < ∞ since these are the conditions under which Y1 can equal 71 and Y2 can equal y2.

Jessica puts away $200 a month for 20 years. How much will she have if she puts it into an annuity paying 6% interest compounded monthly? How much interest does she earn?

Answers

The amount after 20 years is $662.04.

The interest does she earn is $240.

What is compound interest?

Compound interest, also known as interest on principal and interest, is the addition of interest to the loan or deposit principal.

One plus the annual interest rate raised to the number of compound periods minus one is multiplied by the initial loan amount, or principal, to determine compound interest.

Given:

Jessica puts away $200 a month for 20 years.

P = $200

t = 20 years

r = 6% = 0.06

n = 12 (compounded monthly)

Consider the compound interest formula,

[tex]A = P(1+\frac{r}{n})^n^t[/tex]

Plug the values of P, r, n and t in the above equation.

[tex]A = 200(1+\frac{0.06}{12})^1^2^*^2^0\\ A = 200(1+0.005)^2^4^0\\A = 200(1.005)^2^4^0\\A = 662.04089\\A = 662.04[/tex]

Hence, the amount after 20 years is $662.04.

Now to find the interest does she earn.

Interest = Principle x time x rate

             = 200 x 20 x 0.06

Interest = $240

Hence, the interest does she earn is $240.
