Answer:

[tex]3-\sqrt{11}[/tex]

Step-by-step explanation:

If you want rational coefficients then you would want the conjugate of any irrational zero given.

The question is equivalent to what is the conjugate of [tex]3+\sqrt{11}[/tex].

The conjugate of [tex]3+\sqrt{11}[/tex] is [tex]3-\sqrt{11}[/tex].

In general, the conjugate of a+b is a-b

or the conjugate of a-b is a+b.

Or maybe you like this explanation more:

Let [tex]x=3+\sqrt{11}[/tex]

Subtract 3 on both sides:

[tex]x-3=\sqrt{11}[/tex]

Square both sides:

[tex](x-3)^2=11[/tex]

Subtract 11 on both sides:

[tex](x-3)^2-11=0[/tex]

Use difference of squares to factor. I apply [tex]u^2-v^2=(u-v)(u+v)[/tex].

[tex]([x-3]-\sqrt{11})([x-3]+\sqrt{11})=0[/tex]

So you have either

[tex][x-3]-\sqrt{11}=0[/tex] or [tex][x-3}+\sqrt{11}=0[/tex]

Solve both for x-3 and then x.

Add sqrt(11) on both sides for first equation and subtract sqrt(11) on both sides for second equation:

[tex]x-3=\sqrt{11}[/tex] or [tex]x-3=-\sqrt{11}[/tex]

Add 3 on both sides:

[tex]x=3+\sqrt{11}[/tex]  or [tex]x=3-\sqrt{11}[/tex]

Answer:

the answer is C.

Step-by-step explanation:

The perimeter of a rectangle with sides of 14 ft and 8 ft is 44 ft.

The perimeter of a rectangle is calculated by adding all its sides. For a rectangle with sides of 14 ft and 8 ft, the perimeter is found by adding twice the length and twice the width:

Perimeter = 2(length + width)
Perimeter = 2(14 + 8) = 2(22) = 44 ft

Answer:

2πrh unit^2.

Step-by-step explanation:

The lateral area is  the circumference of the base * the height =  2πrh.

The lateral area of a right cylinder with height equal to h and r as the radius is 2πrh. Therefore, option C is the correct answer.

All of the sides of the object are the lateral surface of an object, except its base and top (when they exist). The lateral surface area is the lateral surface zone. This is to be distinguished from the overall surface area, which, along with the base and top areas, is the lateral surface area.

The surface area that a cylinder's curved surface alone covers is known as the curved surface area (CSA) or lateral surface area. The curved surface area of a cylinder is computed using the formula 2πrh, where  height of the cylinder is h and the radius of the base is r.

Therefore, option C is the correct answer.

Step-by-step explanation:

Using the trigonometric ratios we can find the sides of the triangle with the acute angles.

In the triangle provided we will use COSINE

Cos ∅=adjacent/hypotenuse

Let us substitute with the values in the question into the formula.

Tan 45 =2/x

x=2/Cos 45

Answer: SECOND OPTION.

Step-by-step explanation:

You can use the following identity:

[tex]cos\alpha=\frac{adjacent}{hypotenuse}[/tex]

In this case:

[tex]\alpha=45\°\\adjacent=2\\hypotenuse=x[/tex]

Therefore, in order to calculate the value of "x", you need to substitute values into [tex]cos\alpha=\frac{adjacent}{hypotenuse}[/tex] and solve for "x".

This is:

[tex]cos(45\°)=\frac{2}{x}\\\\xcos(45\°)=2\\\\x=\frac{2}{cos(45\°)}\\\\x=2\sqrt{2}[/tex]

Answer:

1. Length when found = length at birth + (age when found × growth each year); 2. 6.3 yr

Step-by-step explanation:

1. The word equation

Length when found = length at birth + (age when found × growth each year)

2. The calculations

                            5 m = 2.6 m + (age when found × 0.38 m/yr)  

Do the multiplication first (PEMDAS)

                            5 m = 2.6 m + 0.38 × age when found m/yr

Subtract 2.6 m from each side of the equation

                           2.4 m = 0.38 × age when found m/yr

Divide each side by 0.38 m/yr

                           6.3 yr = age when found

The killer whale is 6.3 yr old.

ANSWER

[tex]x = - \frac{2}{9} [/tex]

EXPLANATION

The given equation is :

[tex] \frac{2}{5}(x - 2) = 4x[/tex]

We multiply both sides by [tex] \frac{5}{2} [/tex]

[tex] \frac{5}{2} \cdot\frac{2}{5}(x - 2) = 4x \times \frac{5}{2} [/tex]

We simplify to obtain:

[tex]x - 2 = 10x[/tex]

Group similar terms to obtain:

[tex] - 2 = 10x - x[/tex]

Simplify the right hand side.

[tex] - 2 = 9x[/tex]

Divide both sides by 9.

[tex] \frac{ - 2}{9} = \frac{9x}{9} [/tex]

[tex] - \frac{2}{9} = x[/tex]

Or

[tex]x = - \frac{2}{9} [/tex]

The second choice is correct

The solution for [tex]x[/tex] is [tex]x = -\frac{2}{9}[/tex].

To solve the equation [tex]\frac{2}{5} (x - 2) = 4x[/tex], we need to perform the following steps:

Distribute the Fraction:
We start by distributing [tex]\frac{2}{5}[/tex] to both terms inside the parentheses:
[tex]\frac{2}{5}x - \frac{2}{5} \cdot 2 = 4x[/tex]
This simplifies to:
[tex]\frac{2}{5}x - \frac{4}{5} = 4x[/tex]

Isolate the Variable:
Next, we want to get all terms involving [tex]x[/tex] on one side. We can do this by subtracting [tex]\frac{2}{5}x[/tex] from both sides:
[tex]-\frac{4}{5} = 4x - \frac{2}{5}x[/tex]

Now, we can combine the [tex]x[/tex] terms on the right:
[tex]4x - \frac{2}{5}x = \left(4 - \frac{2}{5}\right)x = \left(\frac{20}{5} - \frac{2}{5}\right)x = \frac{18}{5}x[/tex]
Thus, we have:
[tex]-\frac{4}{5} = \frac{18}{5}x[/tex]

Solve for x:
Now, we want to solve for [tex]x[/tex] by multiplying both sides of the equation by the reciprocal of [tex]\frac{18}{5}[/tex], which is [tex]\frac{5}{18}[/tex]:
[tex]x = -\frac{4}{5} \cdot \frac{5}{18} = -\frac{4}{18} = -\frac{2}{9}[/tex]

Given the multiple-choice options of [tex]\frac{2}{9}[/tex], [tex]9[/tex], [tex]-\frac{2}{9}[/tex], and [tex]-\frac{9}{2}[/tex], the correct answer is negative 2 over 9.

Answer:

204 in^3

Step-by-step explanation:

The volume of the base square is V=lwh.

When we substitute our givens, it becomes V=6(4)(2). This equals 48 in^3.

The volume of the triangle is V=.5lwh.

When we substitute our givens, it becomes V=.5(6)(4)(15-2). This equals 156 in^3.

When we add 48 and 156, we get 204 in^3.

Answer:

Option D. is the answer.

Step-by-step explanation:

Option A.

From the table we can see that for the value of x = 3, there are two values of y (14 and 19).

Which is not possible for a function. It should be one to one.

So option A is not a function.

Option B.

In this option again we have two values of y = 0, -5 for the value of x = 3.

For a function values of x and y should be one to one.

Therefore, it's not a function.

Option C.

Here for x = -1, there are two values of y (y = -11 and 5).

Therefore, it's not a function.

Option D.

In the given graph we find that there are different values of y for every value of x.

Therefore, Option D is the answer.

Apply the rule to this case:

[tex] 27^{\frac{1}{5}} = \sqrt[5]{27} [/tex]

The graph shows the solutions:

The polynomial follows:   y = (x + 3)(x - 1)(x - 5)

.

Answer:

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

Step-by-step explanation:

The graph crosses the x axis at the points -3,1,5

These are also called the zeros

f(x) =k (x-a) (x-b) (x-c) .....

where a,b,c,... are the zeros of the function and k is a constant

f(x) = k * (x--3) (x-1) (x-5)

f(x) = k(x+3) (x-1) (x-5)

To help determine the value of k

Take another point  at x = 0, we know the value is positive

f(0) = k(3) (-1) (-5)

f(0) = k(15)

That means k must be greater than 0  Looking at the graph, it should be around 1

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

Answer:

Mary: 16

Kevin: 22

Ahmed: 88

Step-by-step explanation:

This could be written as the following formula.

Mary + Kevin + Ahmad = 126

and we know that

Mary + 6 = Kevin

Kevin * 4 = Ahmed

so Ahmed = (Mary + 6) * 4

When filling this in you get

Mary + Mary + 6 + (Mary + 6) * 4 = 126

Mary + Mary + 6 + 4Mary + 24 = 126

6Mary + 30 = 126

6Mary = 96

Mary = 16

So Mary served 16 orders.

Using the earlier formulas you get

Kevin = Mary + 6 = 16 + 6 = 22

Ahmed = Kevin * 4 = 22 * 4 = 88.

Now we just need to double check it.

Mary + Kevin + Ahmad = 16 + 22 + 88 = 126. Which matches what it should be.

Step-by-step explanation:

x - y = 7...eqn 1

x^2 + y = 125...eqn 2

making y the subject of the formula in eqn 1

=> y = x -7...eqn 3

subst for y from eqn 3 in eqn 2

=> x^2 + x-7 = 125

=> x^2 + x - 132 = 0

=> (x + 12) (x -11) =0

x = 11 or -12

when x = 11, y = 4

when x = -12, y = -19

Answer:

The largest numbers is either -12 or 11

Step-by-step explanation:

Let the numbers be a and b and a be the largest number.

The difference of two numbers is 7

        a - b = 7 ------------------------- eqn 1

The sum of the smaller number and the square of the larger number is 125

        a² + b = 125 ------------------------- eqn 2

eqn 1 + eqn 2

       a² + a - 132 = 0

       ( a + 12 ) (a - 11) = 0

        a = -12 or a  = 11

So the largest numbers is either -12 or 11

The sum of the geometric series is approximately 435.4, according to the formula for geometric series summation.

To find the sum (Sn) of a geometric series, you can use the formula:

[tex]\[ Sn = \frac{{a_1 \cdot (1 - r^n)}}{{1 - r}} \][/tex]

Where:

[tex]- \( a_1 \) is the first term\\- \( r \) is the common ratio\\- \( n \) is the number of terms[/tex]

Given:

[tex]\( a_1 = 0.28 \)\( a_5 = 362.88 \)\( r = 6 \)[/tex]

We need to find [tex]\( n \)[/tex]. Since [tex]\( a_5 \)[/tex] is the fifth term, we can use the formula for the nth term of a geometric series:

[tex]\[ a_n = a_1 \cdot r^{(n-1)} \][/tex]

Substitute the values we have:

[tex]\[ 362.88 = 0.28 \cdot 6^{(5-1)} \]\[ 362.88 = 0.28 \cdot 6^4 \]\[ 362.88 = 0.28 \cdot 1296 \]\[ 362.88 = 363.648 \][/tex]

So, [tex]\( n = 5 \).[/tex]

Now, plug the values into the sum formula:

[tex]\[ S_5 = \frac{{0.28 \cdot (1 - 6^5)}}{{1 - 6}} \]\[ S_5 = \frac{{0.28 \cdot (1 - 7776)}}{{-5}} \]\[ S_5 = \frac{{0.28 \cdot (-7775)}}{{-5}} \]\[ S_5 = \frac{{-2177}}{{5}} \]\[ S_5 = -435.4 \][/tex]

Since the sum of a series cannot be negative, the correct answer is option:

a. 435.4

Step-by-step explanation:

The end behavior of the function y = 10x9 – 4x is such that as x approaches infinity, y approaches infinity, and as x approaches negative infinity, y approaches negative infinity. This is because the degree of the polynomial is odd and the leading coefficient is positive.

The end behavior of a polynomial function describes what happens to the function values (y-values) as x approaches infinity and negative infinity. In your function, y = 10x9 – 4x, the highest power of x is 9, and it's coefficient is positive.

According to the rules of end behavior, if the degree (highest power) of the polynomial is odd, and the leading coefficient (the number in front of the highest power) is positive, as x approaches positive infinity, y also approaches positive infinity, and as x approaches negative infinity, y approaches negative infinity.

In simpler terms, this means that the graph of your function starts in the third quadrant (bottom-left) and ends in the first quadrant (top-right). Hence, the end behavior of this function can be described as: as x approaches infinity, y approaches infinity; and as x approaches negative infinity, y approaches negative infinity.

Answer: C

Step-by-step explanation: the answer is C on edge :)

The question appears to be about finding the midpoint of segment AH, which involves dividing the segment into two equal parts, either by measurement or by averaging the coordinates of A and H if available.

The question seems to be asking about identifying the midpoint of a line segment in a geometric construction. However, the provided text alludes to various geometric proofs and theorems, rather than directly providing information about finding midpoints.

To find the midpoint of segment AH, one would need to measure the length of AH and then divide it by 2 to find the center point. If the points A and H are on a coordinate plane, the midpoint can be found by calculating the average of the x-coordinates and the y-coordinates of the endpoints A and H. Without specific coordinates or measurements, a more detailed answer cannot be provided.

The midpoint of AH is (0, 4).

Let's assign coordinates to the points A and H to make it easier to calculate the midpoint. Suppose A is at (x1, y1) and H is at (x2, y2).

The formula for finding the midpoint M of a line segment with endpoints (x1, y1) and (x2, y2) is:

[tex]M = \left( \frac{x1 + x2}{2}, \frac{y1 + y2}{2} \right)[/tex]

If we assume A is at (0, 0) and H is at (0, 8) (since H is directly 'below' A on a vertical line), the coordinates are as follows:
A = (0, 0)
H = (0, 8)

Now, applying the midpoint formula:

[tex]M = \left( \frac{0 + 0}{2}, \frac{0 + 8}{2} \right) = (0, 4)[/tex]

Arrange the data in ascending order.

30, 41, 45, 48, 52, 55, 56, 57

Mean of shop A is

[tex]Mean=\frac{\sum x}{n}=\frac{30+41+45+48+52+55+56+57}{8}=48[/tex]

[tex]Median=\frac{(\frac{n}{2})th+(\frac{n}{2}+1)th}{2}=\frac{48+52}{2}=50[/tex]

The data set for shop B is

45, 42, 57, 48, 11, 10, 46, 43

Arrange the data in ascending order.

10, 11, 42, 43, 45, 46, 48, 57

Mean of shop A is

[tex]Mean=\frac{\sum x}{n}=\frac{10+11+42+43+45+46+48+57}{8}=37.75[/tex]

[tex]Median=\frac{(\frac{n}{2})th+(\frac{n}{2}+1)th}{2}=\frac{43+45}{2}=44[/tex]

Both data distribution are not symmetric, so it is better to describe the centers of distribution in terms of median for both coffee shops. Therefore the correct option is B.

Answer:

B. & E.

Step-by-step explanation:

First, to find your slope, put your line into slope-intercept form.

[tex]y=mx+b\\[/tex]

[tex]3x-4y=7\\-4y=-3x+7\\y=\frac{3}{4} x-\frac{7}{4}[/tex]

Your slope is [tex]\frac{3}{4}[/tex].

Now, you can find the y-intercept of your parallel line by plugging your given point and your slope into point-slope form.

[tex]y-y1=m(x-x1)\\y-(-2)=\frac{3}{4} (x-(-4))\\y+2=\frac{3}{4} (x+4)\\y+2=\frac{3}{4} x+3\\y=\frac{3}{4} x+1[/tex]

Your y-intercept is 1.

If you notice, answer choice E is equivalent to one of our steps in converting it to point-slope form. Therefore, E is one of your answers.

The equation of your parallel line is:

[tex]y=\frac{3}{4} x+1[/tex]

B is also a correct answer.

If you put B into slope-intercept form, you get the following:

[tex]3x-4y=-4\\-4y=-3x-4\\y=\frac{3}{4} x+1[/tex]

This, of course, is equivalent to the parallel line which we already found, so we know it is parallel.
