68. The product of a nonzero integer and -1 has the same value as the square of the integer. What is the integer?
(F) -2
(G) -1
(H) 0
(J) 1
(K) 2

Answer:

m =  [tex]\frac{6}{5}[/tex]

Step-by-step explanation:

First, we must rewrite 5x + 6y = - 18 to the form y = mx + b.

5x + 6y = -18

6y = -5x - 18

y = [tex]\frac{-5}{ 6}[/tex]x - 3

The equation of a perpendicular line to y = [tex]\frac{-5}{ 6}[/tex]x - 3 must have a slope that is the negative reciprocal of the original slope.

So, the slope of the perpendicular line is

m = [tex]\frac{6}{5}[/tex]

After looking at the provided number lines, it is clear that the number line (B) accurately reflects 1/4 + 1 < 5.

A number line is a diagram of a graduated straight line used to represent real numbers in introductory mathematics.

It is assumed that every point on a number line corresponds to a real number and that every real number corresponds to a point.

A number on the left of a number line is always smaller than a number on the right.

A number to the right is always greater than a number to the left, too.

So, the inequality we have is:

1/4 + 1 < 5

Now, after observing the given lines, we can easily tell that the number line (B) represents 1/4 + 1 < 5 perfectly.

The future value of Ted's investment after 30 years would be approximately $13,711.86.

What is statistics?

Statistics is a branch of mathematics that deals with the collection, analysis, interpretation, presentation, and organization of numerical data.

Ted can use the formula for the future value of an annuity to calculate the future value of his investment:

FV = Pmt x (([tex](1 + r)^{n}[/tex]) - 1) / r

Where:

FV = Future Value

Pmt = Payment per period (monthly in this case)

r = Interest rate per period (monthly in this case)

n = Number of periods (in this case, 30 x 12 = 360 months)

Substituting the given values, we get:

FV = $250 x (([tex](1 + 0.062/12)^{360}[/tex] - 1) / (0.062/12)

FV = $250 x (283.8576) / 0.0051667

FV = $13,711.86

What is probability?

Probability can be used to calculate an event's probability. It can only be used to assess the possibility that an event will occur. A scale from 0 to 1, where 0 is impossible and 1 is a particular occurrence.

We are given that out of the 400 components, 68 are defective and 332 are non-defective computer components.

A random sample of 25 is taken.

So,

Using the area formula, the length of the sides of the two squares are 22 cm and 25 cm respectively.

A square is a regular quadrilateral in Euclidean geometry, which means that it has four equal sides and four equal angles.

It can alternatively be explained as a rectangle with two neighboring sides that are of equal length.

The square's four sides are equal to one another or congruent.

The square's opposing sides run parallel to one another.

The square's diagonals form a 90° angle with one another.

The square's two diagonals are equal to one another.

Area: s²

s² + (s+3)² = 1017

s² + s² + 9 = 1017

s² = 1008/2

s² = 504

s = ²504

s = 22.44

The interest on $58,254.26 was calculated to be $146.38, the payment to principal was calculated to be $182.62, and the new principal was calculated to be $58,071.64.

Payment is the transfer of funds from one party to another in exchange for goods, services, or to fulfill a legal obligation. Payment can take various forms, including cash, check, credit card, money order, or electronic transfer. Payment can be made in person, over the phone, or online. The most important aspect of payment is that it is a legally binding contract between two parties. Payment is an important part of the economic system that facilitates the exchange of goods and services and helps to ensure that all parties involved receive what they expect from the transaction.

The interest on $58,254.26:
To calculate the interest on $58,254.26, we first need to determine the interest rate. Assuming that the interest rate is 3%, we can calculate the interest owed as follows:

Interest = Principal x Interest Rate x Time

Interest = $58,254.26 x 0.03 x 1/12

Interest = $146.38

b) The payment to principal:
To calculate the payment to principal, we need to subtract the interest from the total payment amount.

Payment to Principal = Total Payment – Interest

Payment to Principal = $329 - $146.38

Payment to Principal = $182.62

c) The new principal:
To calculate the new principal, we need to subtract the payment to principal from the original principal.

New Principal = Original Principal – Payment to Principal

New Principal = $58,254.26 - $182.62

New Principal = $58,071.64

In conclusion, the interest on $58,254.26 was calculated to be $146.38, the payment to principal was calculated to be $182.62, and the new principal was calculated to be $58,071.64.

Step-by-step explanation:

            Men : Women = 5 : 9

Number of men = 5x

Number of women = 9x

42 women left the museum.

Number of remaining women = 9x - 42

              New ratio = 2 : 3

                      [tex]\dfrac{5x}{9x -42}=\dfrac{2}{3}\\\\\\\bf Cross \ multiply,[/tex]

                          3*5x  = 2*(9x - 42)

                          15x     = 2*9x - 2*42

                              15x = 18x - 84

                  18x - 84 = 15x

Add 84 to both the sides,

                         18x = 15x + 84

Subtract 15x from both sides,

                18x - 15x = 84

                         3x = 84

Divide both sides by 3,

                            x = 84 ÷ 3

                            x =  28

Number of men = 5 * 28 = 140

Number of women = 9*28 = 252

The value of y for the inverse variation when x = -12 is derived to be equal to 1.

Inverse variation is a mathematical relationship between two variables, in which an increase in one variable leads to a proportional decrease in the other variable. Mathematically, inverse variation can be expressed as y = k/x, where y and x are the two variables, k is a constant of proportionality, and the product of y and x is always equal to k.

when x = 6 and y = -2, then k is derived as:

-2 = k/6

k = -12 {cross multiplication}

when x = -12, y is derived as:

The 999th digit to the right of the decimal point is 9.

Decimal expansion is the representation of a number in decimal form. In decimal expansion, a number is represented using the base-ten positional notation system, where each digit represents a multiple of a power of ten.

For example, the decimal expansion of the number 1234.5678 is:

which simplifies to:

1000 + 200 + 30 + 4 + 0.5 + 0.06 + 0.007 + 0.0008 = 1234.5678

The decimal expansion of a number can be finite or infinite, and it may or may not be a repeating decimal. A repeating decimal is a decimal that has a repeating pattern of digits after the decimal point. For example, the decimal expansion of 1/3 is 0.3333..., with the digit 3 repeating infinitely.

To find the 999th digit to the right of the decimal point, we need to determine the repeating block of digits in the decimal expansion of 9/23.

The remainder when 9 is divided by 23 is 9, so we can start the long division as follows:

         0.3913043478260869565217...

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

23 |    9.00000000000000000000

           - 6

          --------

                30

               -23

               -----

                   7

                    ...

We can see that the decimal expansion of 9/23 repeats after 22 digits, since the remainder becomes 7, which is the same as the remainder we obtained after dividing 9 by 23.

Therefore, the 999th digit to the right of the decimal point is the same as the (999 mod 22)th digit, which is the 9th digit in the repeating block of digits:

0.3913043478260869565217...

So the 999th digit to the right of the decimal point is 9.

Answer:

y = 150x + 3000

Step-by-step explanation:

We can express the cost (y) as a linear function of heater quantity (x) by writing the equation in the slope-intercept form (y = mx + b), where m is the slope (in this case change in cost / change in heater quantity) and b is the y-intercept (when x = 0).

To find the slope (m), we can use the slope formula, which is

[tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex], where x1 and y1 are one point and x2 and y2 are the other point.

If we allow (30, 7500) to represent x1 and y1 and (40, 9000) to represent x2 and y2, our slope is:

[tex]m=\frac{9000-7500}{40-30}\\ \\m=\frac{1500}{10}\\ \\m=150[/tex]

Now, we can find the y-intercept by plugging in the slope and one of the points and solving for b:

[tex]7500=150(30)+b\\7500=4500+b\\3000=b[/tex]

Thus, our equation where y (cost) is a function of x (heater quantity) is y = 150x + 3000
