Answer:

You can represent most things with a partial fraction, anything in the form:

[tex]\frac{f(x)}{(x+\alpha )(x-\beta )}=\frac{A}{(x+\alpha )}+\frac{B}{(x- \beta )}[/tex]

Notice how the roots of the equation from the denominator on the left hand side are used to form the denominations of fractions on the right hand side.

We can now multiply both sides by the denominator on the left hand side.

[tex]f(x)=A(x-\beta )+B(x+ \alpha )[/tex]

We can now setup 2 simultaneous equations by substituting [tex]x[/tex] for your values of [tex]-(- \beta )[/tex] and [tex]-\alpha[/tex] to make [tex]A[/tex] or [tex]B[/tex] 0, allowing you to find the other [tex]A[/tex] or [tex]B[/tex] value.

[tex]f(-\alpha ) = A(-\alpha - \beta) + 0\\f(\beta ) = 0 + B(\beta + \alpha )[/tex]

Answer:

There are 90° in a quarter circle.

Answer:

90 degrees

Step-by-step explanation:

I believe its 90 degrees because if you have half of a protractor it only goes up to 180 degrees but if you have a whole one (dont know if it exists) you will have 360 degrees but if you put that  into fourths it would result it in being 90 degrees.

Answer:

2A/h = b

Step-by-step explanation:

A = 1/2bh​

Multiply each side by 2

2A = 2*1/2bh​

2A = bh

Divide each side by h

2A/h = bh/h

2A/h = b

Answer:

B = 2[tex]\frac{A}{H}[/tex]

Step-by-step explanation:

A = 1/2 BH

Divide by H on both sides.

To get: A/H = 1/2B

Multiply 2 on both sides.

To get 2[tex]\frac{A}{H}[/tex]= B

Given:

The given function is

[tex]y = 200(1.06)^x[/tex]

To find whether the function is growth or decay and the growth of decay.

Formula:

The function [tex]a(1+r )^x[/tex] is said to be an exponential growth, if the value of a > 0 and r > 0

Again, the function [tex]a(1-r )^x[/tex] is said to be an exponential decay, if the value of a > 0 and 0 < r < 1.

Now,

[tex]y = 200(1.06)^x[/tex]

[tex]y = 200(1+0.06)^x[/tex]

Thus, the value of a > 0 and r > 0, then the given function is an exponential growth function.

Therefore,

The given function is an exponential growth function.

Answer:

30 dolls

Step-by-step explanation:

First, divide 100 by the percentage, which is 20, to get the number you need to multiply 6 by. 100/20 = 5. Then, multiply 6 by that number. 6*5 = 30. So, the total number of dolls in Anitas collection is 30.

To check, find 20% of 30 (and make sure it equals 6). To do so, convert 20% to a decimal, which is 0.2. 0.2*30 = 6. So, you have the correct answer.

Answer:

Anita has 30 dolls

Step-by-step explanation:

Let the number of dolls with Anita be x

20% of x = 6

[tex]\frac{20}{100}*x=6\\\\\frac{1}{5}*x=6\\\\x=6*\frac{5}{1}\\\\x=30[/tex]

Answer:

1 foot and a half lol

Step-by-step explanation:

step

by

step

The objects which are more than 1 foot but less than 2 feet are of the measurements 1.1 feet, 1.2 feet, 1.25 feet, and so on.

Measurement is the method of comparing the properties of a quantity or object using a standard quantity.

Measurement is essential to determine the quantity of any object.

Given that,

We have to find the object which has the length of more than 1 foot but less than 2 feet.

Those objects will be having the measurements in between 1 foot and 2 feet.

1 foot is approximately 30.5 cm.

So, the object will be having the length of 30.5 cm to 61 cm.

Hence the required objects will be having the length in between 30.5 cm to 61 cm.

Answer:

15 inches^2

Step-by-step explanation:

The area of a triangle can be found using:

a=1/2 bh

We know the base (b) is 6, and the height (h) is 5, so we can substitute them in

a= 1/2 (6)(5)

a=1/2 (30)

a=15

Answer:

400 yellow 600 blue 1000 pink

Step-by-step explanation:

30 yellow balls, 45 blue balls, and 75 pink balls

initial sample = ratio of 2:3:5

Shipment 2000 = 2:3:5 = 400 yellow 600 blue 1000 pink

2+3 + 5 = 10            1) We add up the ratio

2000/10 = 200       2)We apply the ratio total to shipment total

                                   and divide.

2 x 200 = 400        3)We multiply by 200

3 x 200 =600

5 x 200 = 1000

Simple as that.

Answer:

The collection of balls in the vending machine is a random sample of 150 balls. The percentage of balls of each color in the vending machine can be used as a model for the company’s shipment purchases:

P(yellow) =30/150 = 20%

P(blue) =  45/150= 30%

P(pink) =75/150 = 50%

If the store purchases 2,000 rubber balls, then about 2,000(0.2) = 400 should be yellow, 2,000(0.3) = 600 should be blue, and 2,000(0.50) = 1,000 should be pink.

Answer:

24x + 64y = 384

The linear equation that expresses the situation is 24x + 64y = 384. This equation represents the number of cans of fruit (x) and cans of vegetables (y) processed at different rates. We can check the equation by plugging in values of x and y.

The linear equation that expresses the situation is 24x + 64y = 384. This equation represents the number of cans of fruit (x) processed at a rate of 24 cans per minute and the number of cans of vegetables (y) processed at a rate of 64 cans per minute. The left side of the equation represents the total number of cans processed, and the right side represents the total number of cans in the order, which is 384. We can check this equation by plugging in the values of x and y to ensure that it satisfies the condition of the order. For example, if we plug in x = 4 and y = 3, we get 24(4) + 64(3) = 384, which is true.

Answer:

The number of 7th students on the Jackson Middle School basketball teams is 17 and the number of 8th students on the Jackson Middle School basketball teams is 36

Step-by-step explanation:

Let

x ----> the number of 7th students on the Jackson Middle School basketball teams

y ----> the number of 8th students on the Jackson Middle School basketball teams

we know that

There are 53 students on the Jackson Middle School basketball teams

so

[tex]x+y=53[/tex] -----> equation A

The number of 8th graders is 15 fewer than three times the number of 7th graders

so

[tex]y=3x-15[/tex] ----> equation B

substitute equation B in equation A

[tex]x+(3x-15)=53[/tex]

solve for x

[tex]x+3x=53+15\\4x=68\\x=17[/tex]

Find the value of y

[tex]y=3(17)-15=36[/tex]

therefore

The number of 7th students on the Jackson Middle School basketball teams is 17 and the number of 8th students on the Jackson Middle School basketball teams is 36

Final answer:

To solve the problem, we set up an equation where x represents the number of 7th graders and solved it to find that there are 17 7th graders and 36 8th graders on the Jackson Middle School basketball teams.

Explanation:

The problem states that there are 53 students in total on the Jackson Middle School basketball teams, with the number of 8th graders being 15 fewer than three times the number of 7th graders. Let's denote the number of 7th graders as x. Thus, the number of 8th graders is 3x - 15. The total number of students on the basketball teams is the sum of the 7th and 8th graders, which can be represented by the equation x + (3x - 15) = 53.

Solving the equation:
4x - 15 = 53
4x = 68
x = 17 (number of 7th graders)
3x - 15 = 3(17) - 15 = 51 - 15 = 36 (number of 8th graders)
So, there are 17 7th graders and 36 8th graders on the Jackson Middle School basketball teams.

Answer:

A) Mean

Step-by-step explanation:

The mean of a data set is one of the ways to calculate the center of tendency, center of data, or the "average".

Example of a set of data: 4, 2, 1, 6

Mean = sum of data / number of data

= (4 + 2 + 1 + 6) / 4

= 13 / 4

= 3.25

Other incorrect answers:

Range - this shows the difference between highest and lowest values in a data set.

Using our example:

highest = 6; lowest = 1

Range = highest - lowest

= 6 - 1

= 5

Median - this shows the "middle" of data if you lined them up from least to greatest, and found the number in the middle.

Using our example:

4, 2, 1, 6

1, 2, 4, 6           Reorder from least to greatest

1, 2, 4, 6           Focus on the middle

(2 + 4)/2 = 3      Find the mean of the two middle numbers

Median = 3

Outlier - this names a piece of data that is far off from what the rest of the numbers are

In our example, we have no outliers.

However, if the data was 4, 2, 1, 6, 20

Then the outlier would be 20.
