Since rectangle PQRS is rotated 90 clockwise about the origin what are the coordinates of R' are: A. R' (4, -1).

In Mathematics and Geometry, the rotation of a point 90° about the center (origin) in a clockwise direction would produce a point that has these coordinates (y, -x).

By applying a rotation of 90° clockwise about the center (origin), the coordinates of triangle A'B'C' are as follows;

(x, y)                               →            (y, -x)

Coordinate P (-3, -1)    →  Coordinate P' (-1, 3)

Coordinate Q (-1, -1)     →   Coordinate Q' (-1, 1)

Coordinate R (-1, -4)     →   Coordinate R' (-4, 1)

Coordinate S (-3, -4)     →   Coordinate S' (-4, 3)

Complete Question:

Rectangle PQRS is rotated 90 clockwise about the origin. What are the coordinates of R'?

There is no illustration, so it is impossible to answer this question. I apologize.

Answer:

2y-4-6y-12=4

-4y=20

y= -5

Step-by-step explanation:

because (y+2)(y-2)=y^2-4

so we have the step to let the every part have the same denominator y^2-4

2(y-2)/(y+2)(y-2)  -6(y+2)/(y-2)(y+2)=4/(y-2)(y+2)

the denominators are the same so the equality .we just need the part over be the same 2y-4-6y-12=4

y= -5

Answer:

y-3=3/5x

Step-by-step explanation:

y-y1=m(x-x1)

Where m=slope and (x1, y1) is a point on the line.

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

m=(0-3)/(-5-0)

m=-3/-5

m=3/5

y-3=3/5(x-0)

y-3=3/5(x)

y-3=3/5x

(0, 3) is the y-intercept as it passes through y = 3 at x = 0, or the y-axis.

Slope:

[tex] \frac{y1 - y0}{x1 - x0} = \frac{3 - 0}{0 - ( - 5)} = \frac{3}{5} [/tex]

Equation of a straight line:

y = mx + c

m = slope (3/5)

c = y value of y-intercept (3)

Equation:

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

The value of f(-3) will be zero

Step-by-step explanation:

Given ordered pair of function f is:

(7,0) )(-3,0) (2,0)(9,0)

The general form of ordered pair is (x,y) where x is the element of domain of function and y is the respective range value i.e. x is input and y is output

So,

In order to find the value of f(-3) we have to observe which ordered pair has -3 as input i.e. as first element of ordered pair

The required ordered pair is: (-3,0)

In the required pair, -3 is the input and 0 is the respective output

So,

The value of f(-3) will be zero

Answer:

Perimeter of trapezoid ABEF= 16x +4

Step-by-step explanation:

Since it is an equilateral triangle

AC = BC = BC = 7x - 2

Point E and F is formed at mid point of line AC and BC respectively.

Therefore AE = 1/2 x AC and BF = 1/2 x BC

Perimeter of trapezoid ABEF = AB + EF + AE + BF

AB = 7x - 2

EF = 2x + 8

AE = (7x - 2)/2

BF = (7x - 2)/2

Perimeter = 7x - 2 + 2x + 8 + (7x - 2)/2 + (7x - 2)/2

= 7x - 2 + 2x + 8 + 7x - 2

= 7x + 2x + 7x - 2 + 8 - 2

Perimeter of trapezoid ABEF= 16x + 4

Answer: 3 and 2/3

Step-by-step explanation: To subtract mixed numbers, first subtract the fractions.

Notice here however that we have 1/3 - 2/3 which will gives us a negative fraction. Since this will cause us a lot of trouble, instead, we can rewrite the first mixed number. We can do this by thinking of 6 and 1/3 as 5 + 1 and 1/3 or as 5 + 4/3 by changing 1 and 1/3 into an improper fraction.

So 6 and 1/3 can be written as 5 and 4/3.

Now we have 5 and 4/3 - 2 and 2/3.

Now, subtract the fractions.

So we have 4/3 - 2/3 which is 2/3. Then subtract the whole numbers. 5 - 2 is 3 and now we have the mixed number 3 and 2/3 which is in lowest terms.

Therefore, 6 and 1/3 - 2 and 2/3 = 3 and 2/3.

Since both fractions have common denominators we can just put them into improper fractions.

6 1/3 = 19/3

2 2/3 = 8/3

Now, we can subtract. (When you add or subtract fractions you only add or subtract the numerators, never the denominators.)

19/3 - 8/3 = 11/3

Turn into mixed number.

11/3 → 3 2/3

Answer:

x = 11

Step-by-step explanation:

Given

9x - 43 = 5x + 1 ( subtract 5x from both sides )

4x - 43 = 1 ( add 43 to both sides )

4x = 44 ( divide both sides by 4 )

x = 11

There's a 16% probability that the air-conditioning unit will take longer than 25 minutes to cool a 2000-square-foot home by 1 degree on a 95-degree day with 80% humidity, based on the empirical rule of normal distribution.

To find the probability of the air-conditioning unit taking longer than 25 minutes to cool the house 1 degree, you first have to understand that the situation described follows a normal distribution with a mean (μ) of 24 minutes and a standard deviation (σ) of 1 minute.

Using the Empirical Rule, also known as the 68-95-99.7 rule, we can assess probabilities for normal distributions.

According to the Empirical Rule, approximately 68% of the data falls within one standard deviation of the mean, 95% within two standard deviations, and 99.7% within three standard deviations.

Since we are interested in the time more than 25 minutes, we are looking at the area to the right of the mean plus 1 standard deviation (24 + 1 = 25 minutes).

Approximately 68% of the data falls within one standard deviation (between 23 and 25 minutes), so about 34% is below 25 minutes, and another 34% is above. However, we're interested in the portion beyond 25 minutes, falling in the tail.

Because 50% of the distribution falls above the mean (by definition of a normal distribution), and we account for the 34% within one standard deviation above the mean, this leaves us with 50% - 34% = 16% of data points (times in this case) falling beyond 25 minutes on a 95-degree day with 80% humidity.

One hot dog costs $1.75 and one hamburger costs $2.25

Step-by-step explanation:

Let,

Hot dog = x

Hamburger = y

According to given statement;

7x+2y=16.75   Eqn 1

2x+7y=19.25   Eqn 2

Multiplying Eqn 1 by 2;

[tex]2(7x+2y=16.75)\\14x+4y=33.50\ \ \ Eqn\ 3[/tex]

Multiplying Eqn 2 by 7;

[tex]7(2x+7y=19.25)\\14x+49y=134.75\ \ \ Eqn\ 4[/tex]

Subtracting Eqn 3 from Eqn 4;

[tex](14x+49y)-(14x+4y)=134.75-33.50\\14x+49y-14x-4y=101.25\\45y=101.25[/tex]

Dividing both sides by 45;

[tex]\frac{45y}{45}=\frac{101.25}{45}\\y=2.25[/tex]

Putting y=2.25 in Eqn 1

[tex]7x+2(2.25)=16.75\\7x+4.50=16.75\\7x=16.75-4.50\\7x=12.25[/tex]

Dividing both sides by 7;

[tex]\frac{7x}{7}=\frac{12.25}{7}\\x=1.75[/tex]

One hot dog costs $1.75 and one hamburger costs $2.25

By using a system of linear equations, the cost of one hamburger is computed to be $2.25 and the cost of one hot dog is computed to be $1.75.

This question involves the use of a system of linear equations to solve for the cost of one hot dog and one hamburger. Let us denote the cost of one hot dog as 'd' and the cost of one hamburger as 'h'. We are given two equations from the problem: 7d + 2h = 16.75 and 2d + 7h = 19.25. Now we can solve this system for values of 'd' and 'h'.

First, we can multiply the first equation by 2 and the second by 7 to make the coefficients of 'h' the same in each equation: 14d + 4h = 33.5 and 14d + 49h = 134.75.

Subtracting the first equation from the second gives us 45h = 101.25. Finally, dividing both sides by 45, we find that h = $2.25 which is the cost of one hamburger.

Substitute h = $2.25 back into the first equation: 7d + 2($2.25) = 16.75. Simplifying, we get 7d = $12.25, and dividing both sides by 7 gives us d = $1.75 which is the cost of one hot dog.

314 of the people attending the fun fair are people living in the neighborhood

Step-by-step explanation:

1. Let's review the data given to us for solving the question:

Number of people attending the fun fair = 2,512

Fraction of people attending the fun fair that are students = 5/8

Fraction of people attending the fun fair that are parents = 1/4

Rest of the people attending the fun fair lives in the neighborhood

2. Let's calculate the number of students, parents and people living in the neighborhood

Students:

Fraction of people attending the fun fair that are students = 5/8

5/8 * 2,512 = 1,570

1,570 of the people attending the fun fair are students

Parents:

Fraction of people attending the fun fair that are parents = 1/4

1/4 * 2,512 = 628

628 of the people attending the fun fair are parents

People living in the neighborhood

2,512 - 1,570 - 628 = 314

314 of the people attending the fun fair are people living in the neighborhood

The area will be 2522.60 km^2 after 11 years

Step-by-step explanation:

First of all, we have to form a funtion for the given scenario.

Let

A be the initial area

r be the decrease rate

and t be the time

Let A_n be the area after t years

Then the function can be given by:

[tex]A_n=A(1-r)^t[/tex]

Given

A=4700 km^2

r=5.5%

t=11 years

Putting the value of rate

[tex]A_n=4700(1-0.055)^t\\=4700(0.945)^t[/tex]

The function can be used to calculate the reduced area

Putting t=11

[tex]A_n=4700(0.945)^{11}\\=2522.596[/tex]

Final answer:

To find the forest area after 11 years with an annual decrease of 5.5%, the exponential decay formula can be applied using the initial forest area and the given rate of decrease.

Explanation:

The question is asking how to calculate the decrease in the forest area over a period of time using a fixed percentage decrease per year. We'll use the formula for exponential decay to find the forest area after 11 years, which is expressed by A = P(1 - r)^t, where A is the amount after time t, P is the initial amount, r is the rate of decrease, and t is the time in years.

To compute the forest area after 11 years with an annual decrease of 5.5%, we'll plug P = 4700 km², r = 0.055, and t = 11 years into the formula. Therefore, the calculation is as follows:

A = 4700 × (1 - 0.055)[tex]11^{2}[/tex]

= 5,37,421.5

After calculating the above expression, we will get the reduced forest area in square kilometers.
