The formula for the perimeter of the rectangle is:

P(x) = 14x - 16

We know that for a rectangle of length L and width W the perimeter is given by the formula:

P = 2*(W + L)

In this case we know that:

W = 2x - 1

L = 5x - 7

Replacing that in the perimeter formula we get:

P(x) = 2*(2x - 1 + 5x - 7)

Now we can simplify this so we get:

P(x) = 2*(2x + 5x - 1 - 7)

P(x) = 2*(7x - 8)

P(x) = 14x - 16

That is the perimeter of the rectangle in terms of x.

The equation of the perpendicular bisector for the line is y = 1/3(x) - 2

Given: the endpoints of the line (4,6) and (8,-6)

The bisector of the line will divide the line into two i.e. the bisector will be at the point of the line.

The coordinate of the midpoint can be calculated using the formula below:

Xm = (X1 +X2)/2  and Ym = (Y1 +Y2)/2

Where X1 = 4, Y1 =6 and X2= 8, Y2= -6

Xm = (4+8)/ 2 = 12/2 = 6  and Ym = (6+(-6))/2 = 0/2 = 0

Thus, midpoint(6, 0)

slope  = y2-y1 / x2-x1

Thus, the slope of the line segment (m₁)  = -6-6 / 8-4 = -12/4 = -3

When the two lines are perpendicular, the product of their slope is -1 i.e.

m₁ × m₂ = -1

where m₁ and m₂ represent the slope of the lines

Let the slope of the bisector be  m₂

-3 × m₂ = -1

m₂ = 1/3

Equation of perpendicular bisector with coordinate (6,0):

y - 0 = 1/3(x-6)

y = 1/3(x-6)

y = 1/3(x) - 2

Therefore, the equation for the perpendicular bisector of the line segment is y = 1/3(x) - 2

The length of the other two sides of the rectangular garden is 6 meters and the perimeter of the garden is 18 meters.

According to the question,

We have the following information:

Two sides of a rectangular garden are 3 meters long. The area of the garden is 18 square meters.

We know that the following formula is used to find the area of rectangle:

Length*width = 18

Length*3 = 18

Length = 18/3

Length of the rectangular garden = 6 meters

Now, perimeter of the rectangular garden:

2(length+width)

The exchange rate of US dollars per Australian dollar is 0.72

The exchange rate of Australian dollars per US dollar is 1.39

Exchange rate

Exchange rate is the price of a country's money in relation to another country's money and it is “fixed” when countries use gold or another agreed-upon standard, and each currency is worth a specific measure of the metal or other standard.

Given,

After arriving in Australia, Jason exchanged $750 of US currency for $1,041.67 Australian dollars. Complete the two statements based on this currency exchange.

Here we need to find the exchange rate of US dollars per Australian dollar and Australian dollars per US dollar then round it to the nearest hundredth.

According to the given details,

Total amount in US dollars = $750

Converted amount in Australian dollar = $1,041.67

When we divide the US dollar by the Australian dollar then we get the value of one dollar rate,

=> 750/1041.67

=> 0.719

When we round off it to the nearest hundredth then we get the exchange rate of $1 is 0.72

Similarly, now we have to divide the Australian dollar by the US dollar then we get the value of one dollar rate,

=>  1041.67/750

=> 1.388

When we round off it to the nearest hundredth then we get the exchange rate of $1 is 1.39.

Confidence interval gives the probability that the unknown parameter will fall within a stated range

The confidence interval is constructed using the formula

confidence interval = x-bar ± z(s/√n)

standard deviation, s = 40.5 min

sample size, n = 23

confidence level = 98%

degree of freedom, df = n - 1 = 23 - 1 =22

t score for 98% confidence level and dt of 22 = 2.509

substituting into the formula

= x-bar ± t(s/√n)

= 92.1 ± 2.509 (40.5 / √23)

The terms which are equivalent to the slope in a proportional relationship include:

Proportional relationships are those in which the ratios of two variables are equal. Another way to think about them is that one variable in a proportional relationship is always a constant value multiplied by the other. This is known as the "constant of proportionality."

The proportionality constant is the ratio that connects two given values in a proportional relationship. The constant of proportionality is also known as the constant ratio, constant rate, unit rate, constant of variation, or even the rate of change.

The slope of a line indicates its steepness. Slope is calculated mathematically as "rise over run" (change in y divided by change in x). The slope formula is the rise over run formula, where the fraction consists of a rise, whether the line is going up or down, divided by the run.

2x+28x+48= 30x+48=60+48=108

when x=-3, 11x+6 = -33+6=-27,

2x+28x+48= 30x+48=-90+48=-42

Answer:

I got 28, -27, 108, and -42. See explanation for the answer for which problems

Step-by-step explanation:

11x + 6 = ?

2x + 28x + 48 = ?

x = 2 and x = -3

Let's start with the first equation

Using x = 2

11(2) + 6 = ?

22 + 6 = 28

Using x = -3

11(-3) + 6 =?

-33 + 6 = -27

Second equation

Using x = 2

2(2) + 28(2) + 48 = ?

4 + 56 + 48 = 108

Using x = -3

2(-3) + 28(-3) + 48 = ?

-6 - 84 + 48 = -42

Answer: x=25/4 or 6.25, y=79/16 or 4.9375

Step-by-step explanation:

Normally, we would have to set up a system of linear equations, but in this case we can solve for x and plug in from there. x=5/2 or 2.5 when solving for the variable. Now we go to the second equation, plug for x, and solve for y. 5/2 times 5/2 is 25/4, multiplied by 3 is 75/4. Subtract 75/4 from -1, and divide both sides by -4.

A fraction of one hundred is used to express a quantity or ratio as a percentage. The acronyms "pct," "pct," and occasionally "pc," as well as the percent symbol, "%," are also frequently used.

A % is a numeric expression that lacks both dimensions and a measurement system. The formula to determine the proportion of one number to another is percentage = (Original number/Another number) x 100.

In mathematics, a percentage is a number or ratio that represents a portion of 100. In percentages, 100% is meant. It contains no units.

A %, also known as a decimal or a fraction, is a figure that indicates how many out of 100 we are discussing. For example, "three for the price of one" is a percentage.

Exponential growth or exponential decay are terms used to describe quantities that vary exponentially rather than continuously. Studying bacterial growth, population expansion, and money growth schemes all use exponential growth.

It is given that a town has a population of 16000 and grows at 2.5% every year.

Now we need to  find the time period when the population will reach 24300

So, [tex]24300 = 16000(1+0.025)^{t}[/tex]

24300/16000 = [tex](1+0.025)^{t}[/tex]

24300/16000 = [tex]1.025^{t}[/tex]

1.51875 = [tex]1.025^{t}[/tex]

Taking log on both sides we get,

log(1.51875) = t log(1.025)

0.18148 = t (0.01072)

t = 0.18148/0.01072 = 16.9

Therefore, after 16.9 years the population will reach to 24300.
