Answer 1

Answer:

4 (as in 25/4)

Step-by-step explanation:

Write and solve an equation of ratios:

 x        15

------ = ------

 10       24

Then 24x = 150, and x = 150/24 = 6.25.  This is equivalent to 25/4.

Answer 2

Answer:

x = 25/4

Step-by-step explanation:

If the rectangles are similar, the ratio of the side lengths have to be similar

10         24

------ = --------

x            15

Using cross products

10*15 = 24*x

150=24x

Divide each side by 24

150/24=24x/24

150/24=x

Divide the top and bottom by 6

25/4 = x

A. a measure of center, such as the median
B. a measure of variation, such as the mean absolute deviation
C. a measure of variation, such as the mode
D. a measure of center, such as the interquartile range

Answers

Answer:

the answer would be A.  a measure of center, such as the median

Step-by-step explanation:

A measure of center for a numerical data set summarizes all of its values with a single number, while a measure of variation describes how its values vary with a single number.

Some examples of a measure of center are median and mode. Some examples of a measure of variation are interquartile range and mean absolute deviation.

Let f(x)=x^2+5x-36. Enter the x-intercepts of the quadratic function in the boxes. __and __

please show the work and answer

Answers

Answer:

x = - 9, x = 4

Step-by-step explanation:

The x- intercepts are the values of x where the graph of the function crosses the x- axis.

To obtain them set f(x) = 0, that is

x² + 5x - 36 = 0

To factor the quadratic.

Consider the factors of the constant term (- 36) which sum to give the coefficient of the x- term (+ 5)

The factors are + 9 and - 4, since

9 × - 4 = - 36 and 9 - 4 = + 5, thus

(x + 9)(x - 4) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 9 = 0 ⇒ x = - 9

x - 4 = 0 ⇒ x = 4

Answer:

x=(4,0) and x=(9,0)

complete the square in vertex form y=x^2+18x-2​

Answers

Answer:

y = (x + 9)² - 83

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Given

y = x² + 18x - 2

Obtain vertex form by using the method of completing the square

add/subtract (half the coefficient of the x- term )²

y = x² + 2(9)x + 81 - 81 - 2

  = (x + 9)² - 83

The ANSWER IS Y=(x+9)^2-83

Solve this system of equations using
the substitution method.
y = 3x + 9
y = 5x – 3
I need the answer for X and Y

Answers

Answer: Please Mark Brainliest :) !!

The answer is x= 6 and y= 27.

Step-by-step explanation:

3x + 9 = 5x + 3

-2x + 9 = -3

y = 5x -3

x = 6

y = 5x -3

y = 5(6) -3

y = 27

First, when solving for x, you would need to make one of the equation into standard form, which would be Ax + By = C. So, I'm going to use y = 5x -3.

y = 5x - 3  || subtract -5x on both sides from the equal sign

5x + y = -3  || there you have one equation in standard form

Now, all you have to do now is substitute the y-intercept form equation into the standard form equation. As you can see, you would substitute the y-intercept form into the y in the standard form equation.

5x + y = -3

5x + 3x + 9 = -3  || combine like terms

8x + 9 = -3  || subtract 9 on both sides from the equal sign

8x = 6  || divide by 8 on both sides from the equal sign

x = 0.75  || final answer for x

Then for solving y, take any equation in y-intercept form and substitute with the x in the equation, which I'm going to use y = 3x + 9 in this case.

y = 3x + 9  || substitute with x

y = 3 (0.75) + 9  || multiply 3 and 0.75

y = 3.75 + 9  || add 3.75 and 9

y = 12.75  || final answer for y

Thus, x = 0.75 and y = 12.75.

A circus has 10 performers, of which 4 are magicians.

What is the probability that a randomly selected performer will be a magician?

Simplify your answer and write it as a fraction or whole number.

P(magician) =

Answers

Answer:

40%

Step-by-step explanation:

you would take the number of magicians and divide that number by the total number of performers like this:

4 / 10 = 0.4

which equals 40%

so the probability of selecting a performer and them being a magician would be 40% exactly

i hope this helps :)

The probability of randomly selecting a magician from a group of 10 performers with 4 magicians is [tex]\frac{2}{5}[/tex].

The probability that a randomly selected performer from a circus with 10 performers and 4 magicians will be a magician is calculated by dividing the number of magicians by the total number of performers. Therefore, the probability P(magician) is:

P(magician) = number of magicians / total number of performers
P(magician) = [tex]\frac{4}{10}[/tex]
P(magician) = [tex]\frac{2}{5}[/tex]

Solve the given inequality. Describe the solution set using the set-builder or interval notation. Then, graph the solution set on a number line.

4m +16.5 < 33.5

Answers

Answer:

solution  (-∞,4.25)

Step-by-step explanation:

Given inequality is [tex]4m +16.5 < 33.5[/tex].

Now we need to solve the given inequality. Describe the solution set using the set-builder or interval notation. Then, graph the solution set on a number line.

[tex]4m +16.5 < 33.5[/tex]

[tex]4m < 33.5 - 16.5[/tex]

[tex]4m < 17[/tex]

[tex]m < \frac{17}{4}[/tex]

[tex]m < 4.25[/tex]

Hence solution set using interval notation is given by (-∞,4.25).

Graph will be an arrow pointing to the left of 4.25

Answer:

m < 4.25; (-∞, 4.25).

Step-by-step explanation:

Part 1. Solve the inequality

4m + 16.5 < 33.5

         4m  < 17         Subtracted 16.5 from each side

            m < 4.25     Divided each side by 4

Part 2. Interval notation

The solution set consists of all numbers less than 4.25. We use parentheses to denote numbers that are not included in the interval.

4.25 is not included, because m < 4.25.

-∞ is not included, because we can never reach it.

In interval notation, the solution set is (-∞, 4.25).

Step 3. Number line

The solution set consists of all numbers less than 4.25. We use an open circle to show that  4.25 is not included in the set.

Solve for f.

f+0.2=−3

Answers

Subtract 0.2 by both sides and the your answer is f = -3.2

Answer:

the answer is f=-3.2

Step-by-step explanation:

because with solving linear equations you have to do the opposite of what your doing do like  f+0.2=−3 since your adding you want to subtract instead you want to subtract on both sides so we know 0.2-0.2= 0 so 0.2- -3= -3.2 so that gives us our answer -3.2

Answer:

Abraham Lincoln, the 16th president of the United States, was born on February 12, 1809 and died at the age of 56 on the 4th day of March 1861. Lincoln was the president of the United States for four years from 1861 to 1865. Lincoln was born in Hardin County in the state of Kentucky in a small cabin that only had one room. His parents, Thomas Lincoln and Nancy Hanks were farmers who had a large track of land that measured 348 acres on which their cabin was situated. His parents were uneducated, however.

Lincoln’s political career began in 1832 when he created a political campaign for a political party known as the Whig Party. This party was based on efforts that sought to improve navigation on the neighboring river. Ten years later, Lincoln married the love of his life, Mary Todd, with whom he had four sons. Unfortunately, only one of his four sons did not survive into adulthood. Lincoln’s participation in active national politics took a turn for the better in 1842 when he campaigned and was elected to the US House of Representatives.

What is the inverse of the function below?

Answers

ANSWER

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

EXPLANATION

The given function is

[tex]f(x) = {e}^{x} [/tex]

Let

[tex]y={e}^{x} [/tex]

We interchange x and y.

[tex]x={e}^{y} [/tex]

Solve for y.

[tex]y = ln(x) [/tex]

This implies that,

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

The correct answer is C

Answer:

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

Step-by-step explanation:

Given function is [tex]f\left(x\right)=e^x[/tex].

Now we need to find it's inverse so follow these steps:

Step 1: replace f(x) with y.

[tex]y=e^x[/tex]

Step 2: Switch x and y.

[tex]x=e^y[/tex]

Step 3: Solve for y.

[tex]x=e^y[/tex]

[tex]ln(x)=ln(e^y)[/tex]

[tex]ln(x)=y[/tex]

[tex]y=ln(x)[/tex]

Step 4: Replace y with [tex]f^{-1}(x)[/tex].

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

Hence final answer is [tex]f^{-1}(x)=ln(x)[/tex].

Fill in the blank please help me

Answers

Answer:

8

Step-by-step explanation:

The required value in the fill-in-the-blank is 8, which is completely factored into the product of two binomials: (x-7) and (x-8).

To fill in the blank in the expression x²-15x+56=(x-7)(x-____), we need to find the missing factor that, when multiplied by (x-7), gives us the original quadratic expression.

Factor the quadratic expression x²-15x+56 by finding two numbers that multiply to 56 and add up to -15, which are -7 and -8.

Therefore, we can rewrite the quadratic expression as:

x² - 15x + 56 = (x - 7)(x - 8)

This means that the quadratic expression can be completely factored into the product of two binomials: (x-7) and (x-8).

Thus, the required value in the fill-in-the-blank is 8.

13. Write a function with a zero of 1/2. Explain how you know.

Answers

Answer:

The function is  [tex]f(x)=2x-1[/tex]

Step-by-step explanation:

If a function has a zero of [tex]\frac{1}{2}[/tex].

The we can write  [tex]x=\frac{1}{2}[/tex].

We need to work backwards to obtain the function:

We multiply through by 2 to get:

[tex]2x=1[/tex].

This implies that:

[tex]2x-1=0[/tex]

Hence a function with such zero is  [tex]f(x)=2x-1[/tex]

Answer:

The function is [tex]f(x)=4x-2[/tex]

Step-by-step explanation:

That a function has a zero at a certain number x means that [tex]f(x)=0[/tex]

Let's see an example,

If we have [tex]f(x)=x+2[/tex] (this is what we call function)

and we choose any value for the x,

x = 3

Now we replace it in our function

[tex]f(3)=3+2[/tex]

[tex]f(3)=5[/tex] (this is the image of 3)

Now if we say that x = -2, and replace it in our function

[tex]f(-2)=(-2)+2[/tex]

[tex]f(-2)=0[/tex] , this means that our function has a zero at x = -2

We can find the zeros of our function equaling it to zero and clearing the x, let's see

[tex]x+2=0[/tex]

[tex]x=-2[/tex]  this means that our function has a zero at x = -2

To find a function that has a zero at  [tex] \frac{1}{2}[/tex] , let's think that the result must be [tex]f(x)=0[/tex]

If we have 4 and multiply it by 1/2.

[tex]4)(\frac{1}{2})=2[/tex], now we subtract 2 from this result

[tex]-2 = 0[/tex] , the complete process would be

[tex]4)(\frac{1}{2})-2=0[/tex], we said that [tex] \frac{1}{2}[/tex], then

[tex]4x-2[/tex], now we write it as a function

[tex]f(x)=4(x)-2[/tex]  we know that by replacing the x by 1/2 the result will be zero, which means that [tex] \frac{1}{2}[/tex] is zero of this function

What percent of 75 is 33

Answers

Answer:

33 is 44% of 75

Step-by-step explanation:

First step:

Calculate, what fraction of 75 is 33:

[tex]\dfrac{33}{75}=\dfrac{33:3}{75:3}=\dfrac{11}{25}[/tex]

Second step:

Convert to the percent:

[tex]\dfrac{11}{25}\cdot100\%=(11)(4\%)=44\%[/tex]

33 is 44% of 75.

To determine what percent of 75 is 33, you can use the formula: (part/total) × 100. In this case, the part is 33 and the total is 75.

First, divide 33 by 75: 33 / 75 = 0.44.Next, convert the decimal to a percent by multiplying by 100: 0.44 × 100 = 44%.

Thus, 44% of 75 is 33.
