Responder:

$ 555,911.5

Explicación paso a paso:

Dado

Principal = $ 545,680

Interés = 2,25%

Tiempo = 10 meses = 10/12 años

Debemos buscar la cantidad después de 10 meses.

Monto = Principal + Intereses

Interés = PRT / 100

Interés = 545,680 * 2,25 * 10/1200

Intereses = 12,277,800 / 1200

Interés = 10.231,5

Cantidad = 545,680 + 10,231.5

Cantidad = 555,911.5

por lo tanto, la cantidad después de 10 meses es $ 555,911.5

Answer:

\(\frac{5\sqrt{2} }{2}\)

Step-by-step explanation:

The square cut in half makes the right side a right triangle.

The equation for these types of questions is short side * square root of 2 = long side

So that means that x * \(\sqrt{2}\) = 10

So then divide by square root of 2 on both sides to cancel it out

x = 10/\(\sqrt{2}\)

Then to simplify it multiply the top and bottom by square root of 2, since you can't have an irrational number in the denominator

That makes it \(\frac{10\sqrt{2} }{2}\)

Divide 10/2 to make \(\frac{5\sqrt{2} }{2}\)

Step-by-step explanation:

To find the slope of the line, we need to select any two points on the line and then use the slope formula:

slope = (y2 - y1) / (x2 - x1)

Let's choose the points (-2, 6) and (2, -6) on the line. Then, we can calculate the slope as:

slope = (-6 - 6) / (2 - (-2))

slope = -12 / 4

slope = -3

Therefore, the slope of the line is -3.

The probability distribution of the 1-year HPR on a 30-year U.S. Treasury bond with a coupon of 4.0% is derived to be 1.02.

Probability distribution of yields to maturity a year from now on a 30-year U.S. Treasury bond with a coupon of 4.0% using the table below.

We need to derive the probability distribution of the 1-year holding period return (HPR) on the bond.

First, we calculate the bond price using the current yield to maturity.

Current Yield to Maturity of Bond = 5.0%

Coupon Payment (C) = $4.00

Face Value (F) = $100.00

Therefore, Price of Bond

= PV of all cash flows

= C / YTM * [1 - 1 / (1 + YTM)n] + F / (1 + YTM)n

= $4.00 / 0.05 * [1 - 1 / (1 + 0.05)30] + $100.00 / (1 + 0.05)30

= $76.76 + $23.24

= $100.00

Therefore, the bond is selling at par value.  

To calculate the 1-year HPR,

we use the formula

HPR = (Ending Bond Price - Beginning Bond Price + Coupon Payment) / Beginning Bond Price

= (P1 - P0 + C) / P0

= (P1 / P0) - 1 + (C / P0)

= [(C1 / P1) + 1] - 1 + (C0 / P0)

= [(C1 / P1) - (C0 / P0)] + 1  

We know that Coupon Payment (C) = $4.00,

and the Par Value (F) = $100.00.

Therefore, Coupon Payment for a 1-year period,

C0

= $4.00 * 1 / 2

= $2.00,

C1 = $4.00  

Thus, we get:  

Probability,

P(YTM) YTM Bond Price C1 / P1 C0 / P0 (C1 / P1) - (C0 / P0)

HPR

= 0.05 $100.00 $4.00 $2.00 $0.02 0.02 + 1

= 1.02 0.06 $94.34 $4.00 $2.00 $0.02 0.02 + 1

= 1.02 0.07 $90.29 $4.00 $2.00 $0.02 0.02 + 1

= 1.02 0.08 $86.48 $4.00 $2.00 $0.02 0.02 + 1

= 1.02 0.10 $81.89 $4.00 $2.00 $0.02 0.02 + 1

= 1.02

The probability distribution of the 1-year HPR on a 30-year U.S. Treasury bond with a coupon of 4.0% is given in the above table, where HPR is derived from the Yield-to-Maturity (YTM) probability distribution provided. Therefore, the probability distribution of the 1-year HPR on a 30-year U.S. Treasury bond with a coupon of 4.0% is:   Probability, P(HPR) HPR 0.02 1.02.

Therefore, the probability distribution of the 1-year HPR on a 30-year U.S. Treasury bond with a coupon of 4.0% is derived to be 1.02.

Step-by-step explanation:

The area of a rectangle is the product of its length and breadth. The maximum area enclosed by the fence is 36800 square meter  and the dimensions of the enclosed area are 115 meter and 320 meter.

A rectangle is a type of parallelogram having equal diagonals.

All the interior angles of a rectangle are equal to the right angle.

The diagonals of a rectangle do not bisect each other.

The dimensions of the given rectangle is (650 - 2x) and x.

Then, the area of the given rectangle is A(x)  = x(650 - 2x)

In order to find the maximum area enclosed take the derivative of A(x) and equate it to zero as follows,

(660 - 2x) - 2x = 0

=> 4x = 660

=> x = 660 / 4

=> x = 115

Now, the maximum area is the value of A(x) at x = 115 as below,

= 115 × (650 - 2×115)

= 115 × 320

= 36800

The dimensions for the maximum area are 115 and (650 - 2 × 115) = 320.

Hence, the largest area enclosed is 36800 square meter and the dimensions of the enclosed area are 115 meter and 320 meter.

Answer:

Orthogonal.

Step-by-step explanation:

Given:

u = <10, 0>

v = <0, -9>

In unit vector notation, the above vectors can be re-written as:

u = 10i + 0j

v = 0i - 9j

Now, note the following:

(i) two vectors, u and v, are parallel to each other if one is a scalar multiple of the other. i.e

u = kv

or

v = ku

for some nonzero value of a scalar k.

(ii) two vectors are orthogonal if their dot product gives zero. i.e

u . v = 0

Let's use the explanations above to determine whether the given vectors are parallel or orthogonal.

(a) If parallel

u = k v

10i + 0j = k (0i - 9j)   ?

When k = 1, the above equation becomes

10i + 0j  ≠  0i - 9j

When k = 2,

10i + 0j ≠ 2(0i - 9j)

10i + 0j ≠ 0i - 18j

Since we cannot find any value of k for which u = kv or v = ku, then the two vectors are not parallel to each other.

(b) If Orthogonal

u.v = (10i + 0j) . (0i - 9j)  

[multiply the i components together, and add the result to the multiplication of the j components]

u.v = (10i * 0i) + (0j * 9j)

u.v = (0) + (0)

u.v = 0

Since the dot product of the two vectors gave zero, then the two vectors are orthogonal.

An election system in which each state is divided into geographical regions (districts) and each district is represented by a single representative who wins by receiving the most votes even if it is not a majority is known as First-past-the-post (FPTP).

First-past-the-post (FPTP) is also known as simple majority system. Through this method of voting, the candidate with the most votes in the constituency is declared the winner of the election. This system is used in India in direct elections of Lok Sabha and State Assemblies. While FPTP is simple, it does not always allow for true representation, as a candidate can win despite getting less than half of the votes in a contest. In 2014, the National Democratic Alliance led by the Bharatiya Janata Party won 336 seats with 38.5% of the votes cast. Also, smaller parties that represent specific groups have less voting opportunities in the FPTP.

On election day, voters receive a ballot with a list of candidates. Since only one member of parliament will represent the region, each party has only one candidate to choose.

Voters put a cross next to their favorite candidate. But if they think their favorite has a low chance of winning, they can place a cross next to the one they like with the best chance of winning.

Being one candidate from each party, voters who support that party but do not like their candidate, either vote for the party they do not support or the candidate they do not like.

Answer: The mixed number 5  7/9

We can write the mixed number as 5 & 7/9 to better separate the whole part (5) from the fractional part (7/9)

==================================================

Explanation:

Use this formula

\(a \frac{b}{c} = \frac{a*c + b}{c}\)

to convert from a mixed number to an improper fraction.

Here are the steps in converting 5 & 1/3

\(a \frac{b}{c} = \frac{a*c+b}{c}\\\\5 \frac{1}{3} = \frac{5*3+1}{3}\\\\5 \frac{1}{3} = \frac{16}{3}\\\\\)

Through similar steps you should also have

\(4 \frac{5}{9} = \frac{41}{9}\\\\6 \frac{5}{9} = \frac{59}{9}\\\\\)

---------------

Let's add the amounts needed for the family room and the living room.

\(\frac{41}{9}+\frac{59}{9}\\\\\frac{41+59}{9}\\\\\frac{100}{9}\\\\\)

Subtract off the amount the painter already has

\(\frac{100}{9} - \frac{16}{3}\\\\\frac{100}{9} - \frac{3*16}{3*3}\\\\\frac{100}{9} - \frac{48}{9}\\\\\frac{100-48}{9}\\\\\frac{52}{9}\\\\\)

This improper fraction is the number of gallons of paint that's missing, i.e. the amount the painter needs to buy.

Converting it to a mixed number gets us:

\(\frac{52}{9}=\frac{45+7}{9}\\\\\frac{52}{9}=\frac{45}{9}+\frac{7}{9}\\\\\frac{52}{9}=5+\frac{7}{9}\\\\\frac{52}{9}=5\frac{7}{9}\\\\\)

Note that 52/9 leads to a quotient of 5 and a remainder of 7. The 5 and 7 match with 5 & 7/9

The painter needs to buy 5 full gallons, plus another 7/9 of a gallon. Or we can state it as him needing 5 & 7/9 gallons of paint.

The length of the side of the equilateral triangle is 20.76 inches.

Here it is given that the length of the altitude of the equilateral triangle is 18 inches.

The formula of the altitude(h) of the equilateral triangle is

h = \(\frac{\sqrt{3} }{2}\)a

Here a is the side of an equilateral triangle.

So we have

18 = \(\frac{\sqrt{3} }{2}\)a

a = 18 × 2/\(\sqrt{3}\)

For the rationalization of the fraction multiply numerator and denominator by \(\sqrt{3}\).

a = \(\frac{18 * 2 * \sqrt{3} }{\sqrt{3}\sqrt{3} }\)

  = \(\frac{18 * 2 * \sqrt{3} }{3}\)

  = 6 × 2 × √3

Daniel and Maria must babysit for 6 hours for their total fees to be the same.

To find the number of hours at which Daniel and Maria have the same total fee, we need to compare their fee structures and determine when their fees are equal.

Daniel charges a flat fee of $10 plus $6 per hour. So his total fee can be represented by the equation:

Total fee (Daniel) = $10 + $6 * Number of hours

Maria's total fee is given in the table. We can see that the total fee increases by $4 for every additional hour. So we can represent Maria's total fee by the equation:

Total fee (Maria) = $22 + $4 * Number of hours

To find the number of hours at which their fees are equal, we set the two equations equal to each other and solve for the number of hours:

$10 + $6 * Number of hours = $22 + $4 * Number of hours

Simplifying the equation, we get:

$6 * Number of hours - $4 * Number of hours = $22 - $10

$2 * Number of hours = $12

Dividing both sides by $2, we find:

Number of hours = $12 / $2

Number of hours = 6
