Answer:

\( (0, 8\sqrt{3}) \)  and  \( (0, -8\sqrt{3}) \) are both 14 units from points (-2, 0) and (2, 0).

Step-by-step explanation:

distance formula

\( d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} \)

We want the distance, d, from points (-2, 0) and (2, 0) to be 14.

Point (-2, 0):

\( 14 = \sqrt{(x - (-2))^2 + (y - 0)^2} \)

\( \sqrt{(x + 2)^2 + y^2} = 14 \)

Point (2, 0):

\( 14 = \sqrt{(x - 2)^2 + (y - 0)^2} \)

\( \sqrt{(x - 2)^2 + y^2} = 14 \)

We have a system of equations:

\( \sqrt{(x + 2)^2 + y^2} = 14 \)

\( \sqrt{(x - 2)^2 + y^2} = 14 \)

Since the right sides of both equations are equal, we set the left sides equal.

\( \sqrt{(x + 2)^2 + y^2} = \sqrt{(x - 2)^2 + y^2} \)

Square both sides:

\( (x + 2)^2 + y^2 = (x - 2)^2 + y^2 \)

Square the binomials and combine like terms.

\( x^2 + 4x + 4 + y^2 = x^2 - 4x + 4 + y^2 \)

\( 4x = -4x \)

\( 8x = 0 \)

\( x = 0 \)

Now we substitute x = 0 in the first equation of the system of equations:

\( \sqrt{(x + 2)^2 + y^2} = 14 \)

\( \sqrt{(0 + 2)^2 + y^2} = 14 \)

\( \sqrt{4 + y^2} = 14 \)

Square both sides.

\( y^2 + 4 = 196 \)

\( y^2 = 192 \)

\( y = \pm \sqrt{192} \)

\( y = \pm \sqrt{64 \times 3} \)

\( y = \pm 8\sqrt{3} \)

The points are:

\( (0, 8\sqrt{3}) \)  and  \( (0, -8\sqrt{3}) \)

Answer:

\( \huge{ \bold{ \boxed{ \tt{n = 2}}}}\)

Step-by-step explanation:

\( \text{ - 4n + 14 = - 2(n - 5)}\)

Distribute -2 through the parentheses

\( \text{↦ - 4n + 14 = - 2n + 10}\)

Move 2n to right hand side and change it's sign

\( \text{↦ \: - 4n + 2n + 14 = 10}\)

Move 14 to right hand side and change it's sign

\( \text{↦ \: - 4n + 2n = 10 - 14}\)

Combine like terms

\( \text{↦ \: - 2n = 10 - 14}\)

Remember : The negative and positive integers are always subtracted but posses the sign of bigger integer.

\( \text{↦ \: - 2n = - 4}\)

Divide both sides by -2

\( \rm{↦ \: \frac{ - 2n}{ - 2} = \frac{ - 4}{ - 2}} \)

\( \text{↦ \: n = 2}\)

The value of n is 2 .

Answer:

100 miles

Step-by-step explanation:

Two plans are being offered for the renting of cars.

Plan A:

Cost per week = $200

Cost for each mile = $0.35

Plan B:

Cost per week = $180

Cost for each mile = $0.55

To find:

Number of miles for which the cost is same ?

Solution:

Let the number of miles driven so that the cost becomes the same = \(m\) miles

First of all, let us find the cost for each plan as per \(m\) miles.

Cost as per plan A = Cost per week + Cost for \(m\) miles = $200 + $0.35\(m\)

Cost as per plan B = Cost per week + Cost for \(m\) miles = $180 + $0.55\(m\)

Now, putting both the costs equal to find the value of \(m\):

\(200 +0.35m = 180 +0.55m\\\Rightarrow 20 = 0.20m\\\Rightarrow m = \bold{100\ miles}\)

Therefore, after 100 miles the cost from each plan will be the same.

Step-by-step explanation: 49+9=58

The number which when added to it's square, numerically n² + n = 12 is 3.

Statements that are written in form of numbers, variables and their operations called as numerical form or numerical expression.

Given a number when added to it's square equals 12.

Let the number be 'n' and this statement in numerical form can be written as n² + n = 12.

Now, this is a quadratic equation and the roots must be our required answer.

n² + n = 12.

n² + n - 12 = 0.

Now, two number that multiplied is -12 and when added is 1 they are 4 and -3.

∴ n² + 4n -3n -12 = 0.

n(n + 4) -3(n + 4) = 0.

n + 4 = 0 OR n - 3 = 0.

n = -4 OR n = 3.

Here 3 is the valid option as the question states 'added' if we put (-4) we have to subtract to get 12.

The point in the form (1, y, z) that is equivalent to the given points is (1, 3/5, 3/5).

To find all the points in the form (1, y, z) that are equivalent to the points (2, -1, 0) and (0, -2, 1), we can use the concept of vector equivalence.

Let's consider the vector from (1, y, z) to (2, -1, 0). This vector is (2-1, -1-y, 0-z) = (1, -1-y, -z).

Similarly, the vector from (1, y, z) to (0, -2, 1) is (0-1, -2-y, 1-z) = (-1, -2-y, 1-z).

Since these two vectors are equivalent, we can set them equal to each other:

(1, -1-y, -z) = (-1, -2-y, 1-z)

Simplifying this equation, we get:

y - z = 0

2y + 3z = 3

Therefore, all points in the form (1, y, z) that are equivalent to the given points are given by the equations:

y = z

2y + 3z = 3

Solving this system of equations, we get:

y = 3/5

z = 3/5

So the point in the form (1, y, z) that is equivalent to the given points is (1, 3/5, 3/5).

Answer:11/57

Step-by-step explanation:

a. The price of the consol is approximately $133.33.

b. The new price of the consol would be $100. The price of the consol falls by 24.99% and the interest rate rises by 1%.

c. Your holding period return is approximately -49.99%.

a. The price of the consol can be calculated using the formula for the present value of a perpetuity:

Price = Annual Payment / Interest Rate

In this case, the annual payment is $4 and the interest rate is 3%. Substituting these values into the formula:

Price = $4 / 0.03 ≈ $133.33

Therefore, the price of the consol is approximately $133.33.

b. To calculate the new price of the consol if the interest rate rises to 4%, we use the same formula:

New Price = Annual Payment / New Interest Rate

Substituting the values, we get:

New Price = $4 / 0.04 = $100

The percentage change in the price of the consol can be calculated using the formula:

Percentage Change = (New Price - Old Price) / Old Price * 100

Substituting the values, we have:

Percentage Change in Price = ($100 - $133.33) / $133.33 * 100 ≈ -24.99%

The percentage change in the interest rate is simply the difference between the old and new interest rates:

Percentage Change in Interest Rate = (4% - 3%) = 1%

Comparing the two percentages, we can see that the price of the consol falls by approximately 24.99%, while the interest rate rises by 1%.

c. The holding period return can be calculated using the formula:

Holding Period Return = (Ending Value - Initial Value) / Initial Value * 100

The initial value is the purchase price of the consol, which is $133.33, and the ending value is the price of the consol after one year with an interest rate of 6%. Using the formula for the present value of a perpetuity, we can calculate the ending value:

Ending Value = Annual Payment / Interest Rate = $4 / 0.06 = $66.67

Substituting the values into the holding period return formula:

Holding Period Return = ($66.67 - $133.33) / $133.33 * 100 ≈ -49.99%

Therefore, the holding period return is approximately -49.99%.
