Step-by-step explanation:

(4,-6) is 5 units away from (9,-6)

No. There are two spots in the vertical line. (Vertical line test)

ANSWER

No, there are two points with the same x-coordinates.

EXPLANATION

The relation in the graph is not a function.

There are two points in the relation that have the same x-coordinates.

These points are (1,1) and (1,3).

As a result of this , a vertical line will intersect the graph of the relation at these two points.

Since the graph of the relation does not pass the vertical line test, it is not a function.

1. Domain: The set of natural numbers / Range: The set of natural numbers

2. Shown below

In this problem, we have that the number of frogs in a certain lake is inversely related to the number of snakes in the lake. Hence we are facing an Inverse Variation, so this means that if the number of snakes in the lake increases then the number of frogs in the lake decreases, because snakes eat frogs! The function that describes this is a rational function defined as:

[tex]y=\frac{100}{x}[/tex]

Where:

[tex]x: \ represents \ the \ number \ of \ snakes \ in \ the \ lake \\ \\ y: \ represents \ the \ number \ of \ frogs \ in \ the \ lake[/tex]

As you can see, [tex]x[/tex] is in the denominator, therefore [tex]x\neq 0[/tex]. Since we need to provide a reasonable domain, we say that  the domain is the set of natural numbers and this doesn't include the number 0. Why aren't negative values included in the domain as well? Well, although negative values are included in the function, they aren't reasonable because [tex]x[/tex] represents the number of snakes and you always get positive numbers when counting things.

To get the range, let's take the inverse of this function, so:

[tex]y=f(x)=\frac{100}{x} \\ \\ \\ Interchange \ x \ and \ y: \\ \\ x=\frac{100}{y} \\ \\ \\ Isolate \ y: \\ \\ y=\frac{100}{x} \\ \\ f^{-1}(x)=\frac{100}{x}[/tex]

So the domain of [tex]f^{-1}(x)[/tex] is the range of our given function [tex]y=f(x)[/tex]. As you can see the inverse function is the same as our given function, then the range is the set of natural numbers as well.

First of all, we can define the pattern of the rational function as:

[tex]y=g(x)=\frac{1}{x}[/tex]

So our function will be:

[tex]f(x)=100g(x)=100\frac{1}{x}=\frac{100}{x}[/tex]

So the graph of [tex]f(x)[/tex] will be the same graph of [tex]g(x)[/tex] but it's been stretched vertically by a constant of 100, that is, each y-value is multiplied by 100. Also, since [tex]x \neq 0[/tex] and [tex]y \neq 0[/tex] then at [tex]x=0[/tex] there is a vertical asymptote and at [tex]y=0[/tex] there is an horizontal asymptote. Finally, the graph is shown below for [tex]x>0 \ and \ y>0[/tex], but remember: Whenever [tex]x \ and \ y[/tex] are natural numbers.

Answer:

Both the number of snakes and the number of frogs will be positive, so positive values are reasonable for the domain and range.

Hello There!

Your answer would be the first one.

f(x) = \x/

F of x has to equal f of -x

Answer : 72,000

Ex: Let x be his monthly salary.

The equation to set up would be

7920=0.11x

This equation represents 11% of monthly salary = 7920

To solve you divide 0.11x by 0.11 to get x by itself. then you do what you do to one side to the other. therefore you divide 7920 by 0.11 and you get 72,000

Answer:

Point B is (10 , -4)

Point D is (10/9 , 1)

Step-by-step explanation:

* Lets revise the rule of the point which divides of a line segment in

 a ratio

- If point (x , y) divides the line segment AB, where A is (x1 , y1) and

 B is (x2 , y2) in the ratio m1 : m2

∴ x = [m2(x1) + m1(x2)]/(m1 + m2)

∴ y = [m2(y1) + m1(y2)]/(m1 + m2)

* Now lets solve the problem

- Point C (3.6 , -0.4) divides AB in the ratio 3 : 2, where A is (-6 , 5)

# x = 3.6 , y = -0.4

# A is (x1 , y1) , B is (x2 , y2)

∴ x1 = -6 , y1 = 5

∵ m1 : m2 = 3 : 2

- Substitute these values in the rule

∵ x = [m2(x1) + m1(x2)]/(m1 + m2)

∴ 3.6 = [2(-6) + 3(x2)]/(3 + 2)

∴ 3.6  = [-12 + 3x2]/5 ⇒ multiply both sides by 5

∴ 18 = -12 + 3x2 ⇒ add 12 to both sides

∴ 30 = 3x2 ⇒ divide both sides by 3

∴ 10 = x2

* The x-coordinate of B is 10

∵ y = [m2(y1) + m1(y2)]/(m1 + m2)

∴ -0.4 = [2(5) + 3(y2)]/(3 + 2)

∴ -0.4 = [10 + 3y]/5 ⇒ multiply both sides by 5

∴ -2 = 10 + 3y2 ⇒ subtract 10 from both sides

∴ -12 = 3x2 ⇒ divide both sides by 3

∴ -4 = y2

* The y-coordinate of B is -4

∴ Point B is (10 , -4)

- Point D divides AB in the ratio 4 : 5 where A (-6 , 5) and B (10 , -4)

- To find the coordinates of point D use the same rule above

# D is (x , y)

# A is (x1 , y1) and B is (x2 , y2)

# m1 : m2 is 4 : 5

∵ x1 = -6 and y1 = 5

∵ x2 = 10 and y2 = -4

∵ m1 = 4 and m2 = 5

- Substitute these values in the rule

∵ x = [m2(x1) + m1(x2)]/(m1 + m2)

∴ x = [5(-6) + 4(10)]/(4 + 5) ⇒ multiply the numbers

∴ x = [-30 + 40]/9 ⇒ add

∴ x = [10]/9 ⇒ Divide

∴ x = 10/9

* The x-coordinate of D is 10/9

∵ y = [m2(y1) + m1(y2)]/(m1 + m2)

∴ y = [5(5) + 4(-4)]/(5 + 4) ⇒ multiply the numbers

∴ y = [25 + -16]/9 ⇒ add

∴ y = [9]/9 ⇒ Divide

∴ y = 1

* The y-coordinate of point D is 1

∴ Point D is (10/9 , 1)

Answer:

the other zero is represented by the ordered pair (4, 0)

Step-by-step explanation:

We have the factored expression

[tex]x (x-4)[/tex]

We must find out for what values of x this function is equal to zero.

Then we equal the function to zero and solve for the variable x

[tex]x (x-4)=0[/tex]

The function is equal to zero when one of the two terms of the product is equal to zero.

So

[tex]x =0[/tex]   We already know that this is a solution

or

[tex]x-4=0\\x =4[/tex]

Then the other zero is represented by the ordered pair (4, 0)

Answer:

Dealership A is cheaper. Hope it helps.

Answer:

By comparing both the payments we can say that Dealer A is cheaper by $4.50.

Step-by-step explanation:

Dealership A: The car costs $30,000, and the loan has an annual interest rate of 4.8% for 5 years.

The EMI formula is :

[tex]\frac{p\times r\times(1+r)^{n} }{(1+r)^{n}-1 }[/tex]

Now, p = 30000

r = [tex]4.8/12/100=0.004[/tex]

n = [tex]5\times12=60[/tex]

Putting values in formula we get;

[tex]\frac{30000\times0.004\times(1+0.004)^{60} }{(1+0.004)^{60}-1 }[/tex]

=> [tex]\frac{30000\times0.004\times(1.004)^{60} }{(1.004)^{60}-1 }[/tex]

EMI is = $563.34

Dealership B: The car costs $29,800, and the loan has an annual interest rate of 5.4% for 5 years.

p = 29800

r = [tex]5.4/12/100=0.0045[/tex]

n = [tex]5\times12=60[/tex]

Putting values in formula we get;

[tex]\frac{29800\times0.0045\times(1+0.0045)^{60} }{(1+0.0045)^{60}-1 }[/tex]

=> [tex]\frac{29800\times0.0045\times(1.0045)^{60} }{(1.0045)^{60}-1 }[/tex]

EMI = $567.84

By comparing both the payments we can say that Dealer A is cheaper by $4.50.

To describe the situation, we can write a system of equations. The cost of a dozen chocolate cookies and a dozen oatmeal cookies can be found by solving the system of equations.

To write a system of equations to describe the situation, let's assign variables to the unknown quantities. Let's say the cost of a dozen chocolate cookies is x dollars and the cost of a dozen oatmeal cookies is y dollars.

The first equation represents the sale of 9 dozen chocolate cookies and 8 dozen oatmeal cookies for $110. This can be written as:

9x + 8y = 110

The second equation represents the sale of 9 dozen chocolate cookies and 5 dozen oatmeal cookies for $89. This can be written as:

9x + 5y = 89

We now have a system of two equations with two variables. We can solve this system using any method, such as substitution or elimination, to find the values of x and y.

Once we find the values of x and y, we can determine the cost of a dozen chocolate cookies and a dozen oatmeal cookies, respectively.

Answer:

Step-by-step explanation:

Mean, it is the average of all numbers and most accurately represents the data set.

The best measure of central tendency depends on the data set characteristics: the mean is suitable for outlier-free data, the median is better for skewed data or when outliers are present, and the mode indicates the most common value.

Choosing the Best Measure of Central Tendency

When analyzing a data set, selecting the appropriate measure of central tendency is crucial. The three main measures are the mean, median, and mode. The mean is the arithmetic average and is best used when the data set does not contain outliers that can skew the results. The median is the middle value when the data is ordered and offers a better representation when outliers are present. The mode is the most frequently occurring value and provides insight into the most common data point.

In a symmetrical data set where the data are evenly distributed, all three measures of central tendency—the mean, median, and mode—will be equal or close to each other. In a skewed distribution or when the data contains outliers, the median is generally the most reliable measure of the center, as it is unaffected by extreme values.

Answer: [tex]-\frac{8}{5}[/tex]

Remember: RISE/RUN (y/x). Lines that are increasing have a positive slope, and lines that are decreasing have a negative slope.

You can find the slope in two ways:

1. Useful if the line is graphed: count the units between 2 points on the line.

2. Useful if the line is not graphed: find the difference between the y-coordinate values divided by the difference of the x-coordinate values.

Answer:

[tex]m=-\frac{8}{5}[/tex]

Step-by-step explanation:

Let

The formula to calculate the slope between two points is equal to

[tex]m=\frac{y2-y1}{x2-x1}[/tex]

Answer:

4u= - 4i - 24j

u +w = -9i - 3j

Step-by-step explanation:

The question is on operation of vectors

Given u= -i -6j  and w= -8i+3j

Then 4u = 4{ -i-6j}

4u= - 4i - 24j

u+w= -i -6j + -8i+3j......................collect like terms

= -i -8i + -6j +3j

= -9i + -3j

= -9i - 3j

[tex]{f}^{ - 1} (x) = {x}^{2} - 3[/tex]

EXPLANATION

Given

[tex]f(x) = \sqrt{x + 3} [/tex]

Let

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

Interchange x and y.

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

Square both sides

[tex] {x}^{2} = y + 3[/tex]

Solve for y

[tex]y = {x}^{2} - 3[/tex]

Therefore the inverse of f(x) is

[tex] {f}^{ - 1} (x) = {x}^{2} - 3[/tex]

( option C )

Answer:

x=6.5

Step-by-step explanation:

This question is on intersecting cords and segments that intersect outside the circle

Forming an equation for this relation;

6(x+6)= 5(5+10)

6x+36=5(15)

6x+36=75.............................collect like terms

6x=75-36

6x=39...........................divide both sides by 6

x=6.5

If you cross check with the answer , you’ll find option C to be the most appropriate option.

The difference between the first two terms is 9 and 9 is not a multiple of six, therefore first two are wrong.

Similarly, if you check option D for the first two terms , you get the second term as 27 which is false.

Therefore option C is the answer, also , it satisfies the series.

Final answer:

The correct expression to find the nth term of the given pattern is Option D: [tex]27(2/3)^{(n-1)}[/tex], as it accurately represents the geometric sequence of the provided numbers.

Explanation:

To find the nth term of the given pattern 27, 18, 12, 8, we will consider each option and see which one fits the sequence of numbers.

The first term (n=1) is 27.

The second term (n=2) is 18, which is 27 multiplied by ⅔ or 2/3.

The third term (n=3) is 12, which is the second term (18) multiplied by ⅔ or 2/3.

Similarly, the fourth term (n=4) is 8, which is the third term (12) multiplied by ⅔ or 2/3.

We can see that with each step, the term is being multiplied by a factor of ⅔ or 2/3. Therefore, an expression that uses multiplication by ⅔ repeatedly would likely represent the pattern.

Let's test the options:

Option A: 27-6n does not fit as it suggests a linear pattern with a constant subtraction, which does not match our sequence.

Option B: 27-6(n-1) also suggests a linear pattern and will not result in the given sequence when evaluated for n=1,2,3,4.

Option C: [tex]27(2/3)^n[/tex] represents a geometric sequence with a common ratio of ⅔, but for n=1, this expression gives us 27*⅔ which is not equal to 27.

Option D: [tex]27(2/3)^{(n-1)}[/tex] when evaluated for n=1 gives us 27*[tex](2/3)^{(1-1)}[/tex] = 27*1 = 27, which is the correct first term of our sequence. Applying this for subsequent terms also gives the correct sequence. Therefore, this is the correct expression for the nth term of the pattern.

Thus, the expression to find the nth term of the pattern is Option D: [tex]27(2/3)^{(n-1)}[/tex].

Answer: [tex]x=-\frac{17}{3}[/tex]

Step-by-step explanation:

Given the equation [tex]\frac{(x+5)}{(x+8)}=1+\frac{6}{(x+1)}[/tex], you need to make the addtition indicated on the right side of the equation:

[tex]\frac{(x+5)}{(x+8)}=\frac{(x+1)+6}{(x+1)}\\\\\frac{(x+5)}{(x+8)}=\frac{(x+7)}{(x+1)}[/tex]

Now, multiply both sides of the equation by (x+8) and (x+1):

[tex](x+1)(x+8)\frac{(x+5)}{(x+8)}=\frac{(x+7)}{(x+1)}(x+1)(x+8)\\\\(x+1)(x+5)=(x+7)(x+8)[/tex]

Now, apply Distributive property:

[tex]x^2+5x+x+5=x^2+8x+7x+56[/tex]

Simplifying, you get:

[tex]6x+5=15x+56[/tex]

Subtract 5 and 15x from both sides:

[tex]6x+5-15x-5=15x+56-15x-5\\\\-9x=51[/tex]

Finally, divide both sidesby -9:

[tex]\frac{-9x}{-9}=\frac{51}{-9}\\\\x=-\frac{17}{3}[/tex]

Answer:

76.8

Step-by-step explanation:

40/250 = 0.16 (1 campers vote)

0.16 x 12 = 1.92

1.92 x 40 = 76.8

To estimate the number of campers who might be interested in tennis lessons, a proportion can be used based on a survey of 40 campers, 12 of whom were interested. Scaling this up to the total 250 campers, approximately 75 campers might be interested in the tennis lessons.

The question is asking us to estimate the number of campers who would be interested in taking tennis lessons at a summer camp. From a small survey of 40 campers, 12 said they would take tennis lessons. To find out how many campers out of the total 250 might be interested, we need to use proportion. The proportion of campers interested in the survey is 12 out of 40, which we can set as equal to x out of 250, where x is the number we want to find. The equation is set up as follows:

12 / 40 = x / 250

Multiply both sides by 250 to isolate x:

250 × (12 / 40) = x

Calculate x:

x = 250 × (12 / 40) = 75

Therefore, the counselors should plan on approximately 75 campers attending next week’s tennis lesson.

Answer:

(-7, -3) (Answer A)

Step-by-step explanation:

We start with the point (-7, -3).  The x-coordinate does not change at all if we reflect this point across the x-axis.  Whereas the y-value of (-7, -3) is -3, we end up with +3 after this reflection.  The desired image is (-7, +3)  (Answer A)

The coordinates of the point (-7, - 3) reflected along the x-axis is

(- 7, 3).

Two-dimensional figures can be transformed mathematically in order to travel about a plane or coordinate system.

Dilation: The preimage is scaled up or down to create the image.

Reflection: The picture is a preimage that has been reversed.

Rotation: Around a given point, the preimage is rotated to create the final image.

Translation: The image is translated and moved a fixed amount from the preimage.

We know reflection along the x-axis of a point (x, y) converts it into a

point (x, - y).

Given, A points (-7, - 3) is reflected along the x-axis.

Therefore, The new coordinates of the points (-7, - 3)  reflected along the x-axis is (- 7, 3).
