Answer:

(1,2) and (4,2)

(2,6) and (6,6)

Step-by-step explanation:

(when a line is horizontal the slope is 0)

[tex]slope = \frac{rise}{run} [/tex]

[tex]rise = y1 - y2[/tex]

[tex] = 2 - 2 \\ = 0[/tex]

[tex]run = x2 - x1 \\ = 4 - 1 \\ = 3[/tex]

[tex]slope = \frac{0}{3} \\ = 0[/tex]

second option

[tex]rise = 6 - 6 \\ = 0[/tex]

run=6-2

=4

slope= 0/4

=0

It will take around 0.24 months for the invested money to get doubled.

The compound interest is a form of interest where the rate of interest is applied on the amount obtained after every interval of time.

The formula to calculate the amount is as follows,

A = P[tex](1 + r)^{(nt)}[/tex]

Substitute all the corresponding values in the above expression to obtain,

A = P[tex](1 + 6/100)^{nt}[/tex]

1800 = 900[tex](1 + 6/100)^{nt}\\[/tex]

=>   [tex](1 + 6/100)^{nt}[/tex] = 1800/900

=>  [tex]1.06^{nt}[/tex] = 2

Since, there are 12 months in one year, n = 12.

[tex]1.06^{12t}[/tex] = 2

=> 12t = log(2) ÷ log(1.06)

=> 12t = 0.275

=> t = 0.02

Which is equivalent to 12 × 0.02 = 0.24 months.

Hence, it will take 0.24 months to double the invested money.

a) The percentage of buyers that paid between $18,000 and $26,000 is; 95%

b) The middle 99.7% of car costs are between $16000 and $28000

c) The probability a car will cost less than $24,000 is; 68%

d) The probability a car will cost more than $26,000 is; 2.5%

The empirical rule of statistics states that 68% of data will be ± 1 standard deviations from the mean, 95% of data will be ± 2 standard deviations of the mean, and 99.7% of data will be ± 3 standard deviations from the mean.

a) We are given;

Mean; μ = $22000

Standard deviation; σ = $2000

$18,000 and $26,000 are both 2 standard deviations from the mean and so, the percentage of buyers is 95%.

b) Since the middle 99.7% of car costs, this is simply 3 standard deviations from the mean and as such it is between the values;

22000 - 3(2000) = $16000 and 22000 + 3(2000) = $28000

c) $24,000 is 1 standard deviation away from the mean and as such the probability will be 68% from empirical rule.

d) $26000 is 2 standard deviations from the mean and as such probability that a car will cost more than that is;

(100% - 95%)/2 = 5%/2 = 2.5%

The given statement is false. If a sample is selected using random sampling methods, the primary reason that the sample mean might be different from the corresponding population mean is not that the sample might be biased.

Because random sampling ensures that results obtained from the sample should approximate what would have been obtained if the entire population had been measured. And the simplest random sample allows all the units in the population to have an equal chance of being selected. In this case, the sample might not be biased.

Random sampling is a part of the sampling technique where each sample has an equal probability of being chosen. A sample chosen randomly is meant to be an unbiased representation of the total population.

The simplification of the given expression is (x - 1)²/ (x-2)(x+3) which restrictions on the domain of this expression are x ≠ 1, 2, -3.

The expression is given in the question as:

(x+3)(x-1)/(x-2) ÷ (x+3)/(x-1)

To simplify the expression (x+3)(x-1)/(x-2) ÷ (x+3)/(x-1), we can start by multiplying the numerator and denominator of the first fraction by the denominator of the second fraction:

(x+3)(x-1)/(x-2) ÷ (x+3)/(x-1)

= (x+3)(x-1) / (x-2) × (x-1) / (x+3)

Then, we can simplify the expression by combining like terms:

= (x - 1)² (x+3)/ (x-2)(x+3)

= (x - 1)²/ (x-2)(x+3)

The restrictions on the domain of this expression are that x cannot be equal to 2 or -3, because these values would make the denominator equal to zero, which is not allowed in a fraction.

Therefore, the domain of the expression is all real numbers except x = 1, x = 2, and x = -3. We can express this as:

Domain: x ∈ R, x ≠ 1, x ≠ 2, x ≠ -3

The money will double in value in approximately 11.6 years.

From the question, we have the following parameters that can be used in our computation:

When the money doubles, the amount is

A = 900 * 2

A = 1800

The compound interest formula is given as

A = P(1 + r/n)^nt

Also from the question, we have

n = 12

This is so because the loan is compounded 12 times in a year as a result of being compounded monthly

Solving further, we replace the variables with their values in the above equation

1800 = 900 * (1 + (6%)/12)^(t*12)

Divide both sides by 900

2 = (1 + (6%)/12)^(t*12)

Also, we have

2 = (1.005)^(t*12)

Take the logarithm of both sides

12t = log(2)/log(1.005)

Evaluate the quotients

12t = 139

Divide both sides by 12

t = 11.6

Hence, the number of years is 11.6 years

It is necessary to compute in the volume of the rotated region while taking into account that each cross section piece is raised up by a height of h = 4 - y. Scale the results by 62.4 lb/ft3 as well.

The given parabolic region's volume of revolution about the y-axis is a parabolic cylinder. This solid is revolved, and it has circular disks as its cross section. The differential volume of one such disk situated at a differential height y above the x-axis must be determined. The weight of water in this volume can then be calculated by multiplying this volume by the density of water. The depth of this volume is then determined from the tank's top surface. Determine how much differential work is needed to lift this water layer to the top surface. Integrate this differential work now to calculate the overall effort needed to empty the tank.

Rotating the curve x=3y about the y-axis creates the region. Keep in mind that 62.5 = (125 / 2) As a result, using the disk method,

The number of routes that Paula can take using graph theory is; E: 4

We will observe that out of the 12 cities, 6 of them possess 3 edges going in/out of them.

The 6 cities are such that there are 2 at the top, 2 at the bottom, and 1 on each side.

In graph theory terms, we can say that they are of degree 3.

Thus, at least 1 edge connecting to each of these cities cannot therefore be used. Furthermore, the same concept applies to the start and end points, due to the fact that we don't want to return to them.

There are 6 + 2 = 8 vertices that we can tell have 1 unused edge, and then we have 17 - 13 = 4 unused edges to work with due to the fact that we have 17 edges in total, and as such must use exactly 13 of them).

Finally, we notice that at each of the 2 cities marked with an O on a path in the image attached, that there are 2 possibilities such that it's either we continue straight and cross back over that same path later, or we will make a left turn, and then turn rightward when we approach the junction again.

The values of x in the first, second, third and fourth triangles are 4 units, 70°, 76° and 80° respectively

To solve this problem, we need some angle geometry knowledge:

For the first triangle:

x = 4 (All sides in a rhombus are identical)

For the second triangle:

The missing side is also equal to x (base of isosceles triangles)

x + x + 40 = 180 (sum of angles in triangle)

2x+40 = 180

2x = 180-40

2x = 140

x = 70°

For the third triangle:

x = 76° (base of isosceles triangles are equal)

For the fourth triangle:

Check the image attached for labeling

m = 180-110 = 70° (angle on a straight line)

y = 70° (base of isosceles triangles are equal)

z = 180-70-70 = 40°

t = 90-40 = 50°

L = 50° (base of isosceles triangles are equal)

The number of acres owned for which the average intake is 2200 calories per day is 2 acres obtained by the algebraic expression that relates the acres of land and the calories per day.

It is given that, the number of calories consumed daily by a person owing x acres of land is given by the algebraic expression,

C(x) = 270 ln(x+1) + 1900

The average intake of calories consumed per day is given by C(x) = 2200

Here x is the number of acres of land. Then, the required number of acres of land is

C(x) = 270 ln(x+1) + 1900

⇒ 2200 = 270 ln(x+1) + 1900

⇒ 270 ln(x+1) = 2200 - 1900

⇒ 270 ln(x+1) = 300

⇒ ln(x+1) = 300/270 = 10/9

Applying base 'e' on both sides, we get

⇒ (x+1) = [tex]e^\frac{10}{9}[/tex]

⇒ x+1 = 3.0377

⇒ x = 3.0377 - 1 = 2.0377

When rounding the final answer to the nearest tenths, we get x = 2 acres.

When rounding the final answer to the nearest thousand, we get x = 2.038 acres.

Thus, for an average intake of 2200 calories per day, the number of acres of land owned is approximately 2 acres.
