which of the following represents the graph of f(x)=1/2^x+2

Answer:

8 - 3 =5

5 is the range of the values given

Step-by-step explanation:

We are only given 2 values;

3 and 8

It seems more reasonable to compute the range of these values as a measure of spread.

The range of a data-set is simply the difference between the maximum and the minimum values.

In our case, the maximum is 8 while the minimum is 3. The range is thus;

8 - 3 = 5

Final answer:

The interquartile range (IQR) is calculated by subtracting the first quartile (Q1) from the third quartile (Q3). If Q1 is 3 and Q3 is 8, the IQR is 5.

Explanation:

The interquartile range (IQR) is the range of the middle 50 percent of the data values, calculated by subtracting the first quartile (Q1) from the third quartile (Q3). If the student asks about the interquartile range between 3 and 8, it seems that they may be referring to the quartiles directly, which would be unusual since quartiles are typically values derived from the data set. However, if we assume that in this case, 3 represents Q1 and 8 represents Q3, then the IQR can be calculated simply as:

IQR = Q3 - Q1 = 8 - 3 = 5.

The IQR indicates the spread of the central half of a data set and is useful in identifying potential outliers and understanding the distribution of data.

Answer:

16 and 82 degrees

Step-by-step explanation:

You can sum all of the angles together and solve for x.

(x - 1) + (5x - 3) + (5x - 3) = 180

11x - 7 = 180

11x = 187

x = 17

The first angle is 16 degrees. (17 - 1)

The other two angles are 82 degrees(5(17) - 3)

Answer:

16 and 82 degrees

Step-by-step explanation:

You can sum all of the angles together and solve for x.

(x - 1) + (5x - 3) + (5x - 3) = 180

11x - 7 = 180

11x = 187

x = 17

The first angle is 16 degrees. (17 - 1)

The other two angles are 82 degrees(5(17) - 3)

Answer:

No, she used the diameter instead of the radius measure.

Step-by-step explanation:

we know that

The volume of the sphere is equal to

[tex]V=\frac{4}{3}\pi r^{3}[/tex]

we have

[tex]r=10/2=5\ units[/tex] ----> the radius is half the diameter

substitute

[tex]V=\frac{4}{3}\pi (5)^{3}[/tex]

[tex]V=\frac{500}{3}\pi\ units^{3}[/tex]

Answer:

No, she used the diameter instead of the radius measure.

Step-by-step explanation:

The formula for the sphere is:

[tex]\pi \frac{4}{3} r^{3}[/tex]

So she should have calculated the radius before inserting the values into the formula, the radius is half the diameter, so the radius of that sphere is 5.

In order to calculate it right you have to put 5 instead of the 10 so teh formula would look like this:

[tex]\pi \frac{4}{3} r^{3}[/tex]

[tex]\pi \frac{4}{3} 5^{3}[/tex]

[tex]\pi \frac{4}{3}(125)[/tex]

[tex]250\pi }[/tex]

The answer would be:

[tex]250\pi }[/tex]

Answer:

The corresponding point of (-3 , 6) is (-3 , 2)

Step-by-step explanation:

* Lets talk about some transformation to solve the problem

- A vertical stretching is the stretching of the graph away from

 the x-axis

- If k > 1, the graph of y = k•f(x) is the graph of f(x) vertically stretched

 by multiplying each of its y-coordinates by k.

- A vertical compression is the squeezing of the graph toward

 the x-axis.

- If 0 < k < 1 (a fraction), the graph is f(x) vertically compressed

 by multiplying each of its y-coordinates by k.

* Now lets solve the problem

∵ f(x) transformed to be 1/3 f(x)

∴ The graph of f(x) is stretched or compressed vertically

∵ k = 1/3

∴ 0 < k < 1

∴ The graph is compressed vertically

- The y-coordinate must be multiplying by k

∵ The y-coordinate of the point is 6

∵ 6 × 1/3 = 2

∴ The image of the point (-3 , 6) is (-3 , 2)

* The corresponding point of (-3 , 6) is (-3 , 2)

Answer: Option B.

Step-by-step explanation:

Given the system of inequalities:

[tex]y<x^2+6[/tex]

[tex]y>x^2-4[/tex]

The solution of the system of inequalities is the region between the parabolas. This region is: below the parabola [tex]y=x^2+6[/tex] and above the parabola [tex]y=x^2-4[/tex]

Then, if a point is a solution of the system, then it must be in the region between this parabolas.

You can observe in the figure attached that the point  that is in this region is the point (2,6), therefore, the answer is the option B.

Answer:

Linear   Quadratic   Exponential

Step-by-step explanation:

Answer:

First table models Linear, second quadratic and third one exponential functions.

Step-by-step explanation:

To find whether the given table models a linear function there should be a constant change in y values with the constant change in x values of the table.

We take the example of first table written as linear.

Here change in x values is

6 - 5 = 1

7 - 6 = 1

8 - 7 = 1

Similarly change in y values is

1 - 4 = -3

-2 - 1 = -3

-5 -(-2) = -3

There is a common difference in y values = -3

So the given table models linear function.

We take the second table.

For quadratic function with the constant change in x values, difference of difference in y values is constant.

Change in x - values

6 - 5 = 1

7 - 6 = 1

8 - 7 = 1

Difference in y values

1 - 0 = 1

4 - 1 = 3

9 - 4 = 5

Now difference in difference of y values

3 - 1  = 2

5 - 3 = 2

Here, difference in difference of y values is 2

So the given table models a quadratic equation.

Now we take the third table.

For exponential function in the form of [tex]f(x) = a(r)^{n}[/tex] there should be a common ratio in the terms of y values.

[tex]\frac{\text{Second term of y}}{\text{First term of y }}= \frac{2}{1}=2[/tex]

[tex]\frac{\text{Third term of y}}{\text{Second term of y }}= \frac{4}{2}=2[/tex]

So there is a common ratio of 2 in each term.

Therefore, the given table models exponential equation.

First table models Linear, second quadratic and third one exponential functions.

Answer:

Step-by-step explanation:

The question here is "how many pages does this book have?"

In 4 hrs, at 55 pages/hr, he reads 220 pages.

Adding the number of pages read (220) to the number of pages left to read (350) yields a total of 570 pages in this book.

Next time, please try to be more specific about what you want to find.  "functions formula" is very ambiguous and unhelpful.

The equation is [tex]\( y = 570 - 55x \)[/tex], where [tex]\( y \)[/tex] is pages left and [tex]\( x \)[/tex] is hours passed.

To complete the equation for the relationship between the number of pages left and the number of hours, we first need to determine the rate at which Naoya is reading the book.

Since he read 55 pages per hour, after 4 hours he would have read [tex]\( 55 \times 4 = 220 \)[/tex] pages.

Given that after 4 hours he still had 350 pages left to read, we can find out how many pages he had initially:

Initial number of pages = Total pages - Pages read

Initial number of pages = 350 pages + 220 pages

Initial number of pages = 570 pages

Now, let's use the formula for the relationship between the number of pages left and the number of hours:

[tex]\[ y = 570 - 55x \][/tex]

Where:

- [tex]\( y \)[/tex] represents the number of pages left to read after [tex]\( x \)[/tex] hours.

- [tex]\( x \)[/tex] represents the number of hours.

So, the complete equation for the relationship is:

[tex]\[ y = 570 - 55x \][/tex]

The complete question is here:

Naoya read a book cover to cover in a single session, at a rate of 55 pages per hour. After 4 hours, he had 350 pages left to read.

Let y represent the number of pages left to read after x hours.

Complete the equation for the relationship between the number of pages left and number of hours.

Answer:

[tex]\frac{x}{y}[/tex] = [tex]\frac{5}{8}[/tex]

Step-by-step explanation:

Given

[tex]\frac{4x-y}{3y}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )

2(4x - y) = 3y ← distribute left side

8x - 2y = 3y ( add 2y to both sides )

8x = 5y ( divide both sides by 8 )

x = [tex]\frac{5}{8}[/tex] y ( divide both sides by y )

[tex]\frac{x}{y}[/tex] = [tex]\frac{5}{8}[/tex]

4. B

5. D

Step-by-step explanation:

2) The sequence is multiplying by -2 each time. This means that it is geometric.

The next two terms would be:

[tex]32*-2=-64\\-64*-2=128\\128*-2=-256[/tex]

This means that the answer is B

3) The sequence is being multiplied by [tex]\frac{1}{3}[/tex] each time. This means that it is geometric.

The next 3 terms would be:

[tex]3*\frac{1}{3} =1 \\\\1*\frac{1}{3} =\frac{1}{3} \\\\\frac{1}{3} *\frac{1}{3} =\frac{1}{9}[/tex]

I am assuming that the answer is C and that you were unable to type the fractions.

4) We know that the common difference is 1.5, so that is the coefficient of our variable and the starting value is 15. This means that we can write an equation as follows

[tex]f(x)=1.5(x-1)+15[/tex]

Now we can find the first 4 terms

[tex]f(1)=15.0\\f(2)=16.5\\f(3)=18.0\\f(4)=19.5[/tex]

This would mean that the answer is B

5) We know that this is a geometric series, we know the common ratio, and we know the first term. This means we can write the equation as follows

[tex]f(x)=4.5(10)^{x-1}[/tex]

Now we can find the first 4 terms

[tex]f(1)=4.5\\f(2)=45\\f(3)=450\\f(4)=4500[/tex]

Unless you meant that the ratio was [tex]\frac{1}{10}[/tex], the answer is D, none of the above

Answer:

8 rabbits

22 chickens

Step-by-step explanation:

c = chickens

r = rabbits

heads - c + r = 30

legs - 2c + 4r = 76

We can now use these two equations to create one by isolating the variable (c) in the first equation.

c = 30 - r

2c + 4r = 76

2(30 - r) + 4r = 76

60 - 2r + 4r = 76

2r = 16

r = 8

Now we know that there are 8 rabbits, which means that there has to be 22 chickens in order to have 30 heads.

To solve the problem of finding the number of chickens and rabbits, we can use a system of equations.

To solve this problem, we can use a system of equations. Let's consider the number of chickens as 'c' and the number of rabbits as 'r'.

We know that there are a total of 30 heads, which means that c + r = 30.

We also know that there are a total of 76 legs, which means that 2c + 4r = 76.

We can solve this system of equations by substitution or elimination to find the values of c and r. From there, we can determine the number of chickens and rabbits that Jessie has.

Let's solve it using the elimination method: Multiply the first equation by 2 to match the coefficient of 'c' in the second equation. You will get 2c + 2r = 60. Subtract this equation from the second equation to eliminate 'c', and you will get 2r - 2r = 76 - 60. Simplifying, we have 0 = 16, which is not true.

There is no solution for this system of equations. Therefore, the problem may be set up incorrectly.

Answer:

m∠1 = 123°

Step-by-step explanation:

Since a straight line is always a supplementary angle, it equals 180°. To solve for the unknown angle, we can subtract the known angle from 180°.

180° - 57° = 123°

So m∠1 = 123°

180-57= 123 is the measurement for angle 2

1, 0 (B)

7, 1 (D)

49, 2 (E)

1/7, -1 (G)

1/49, -2 (H)

Step-by-step explanation:

Powers of 7 are ...

7^-2 = 1/7^2 = 1/49

7^-1 = 1/7^1 = 1/7

7^0 = 1

7^1 = 7

7^2 = 49

The log (base 7) of the number on the right is the exponent on the left. That is ...

I think ab is an expression or the product of two factors.

Answer:

AB = 21 and DE = 23

Step-by-step explanation:

Given 2 intersecting chords inside the circle then

The products of the measures of the parts of one chord is equal to the products of the measures of the parts of the other chord, that is

x(x + 13) = (x + 10)(x + 1) ← distribute parenthesis on both sides

x² + 13x = x² + 11x + 10 ← subtract x² + 11x from both sides

2x = 10 ( divide both sides by 2 )

x = 5

Hence

AB = x + 10 + x + 1 = 2x + 11 = (2 × 5) + 11 = 10 + 11 = 21

DE = x + x + 13 = 2x + 13 = (2 × 5) + 13 = 10 + 13 = 23
