Answer:

x = 2 or

x = 9

Step-by-step explanation:

x² - 11x + 18 = 0

x² - 9x - 2x + 18 = 0

x(x - 9) - 2(x - 9) = 0

(x - 2)(x - 9) = 0

x - 2 = 0 or x - 9 = 0

x = 2 or x = 9

Thus, x = 2 or 9

-TheUnknownScientist

Answer:

x = 2, x = 9

Step-by-step explanation:

Given

x² - 11x + 18 = 0

Consider the factors of the constant term (+ 18) which sum to give the coefficient of the x- term (- 11)

The factors are - 2 and - 9 , since

- 2 × - 9 = + 18 and - 2 - 9 = - 11 , thus

(x - 2)(x - 9) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 2 = 0 ⇒ x = 2

x - 9 = 0 ⇒ x = 9

Answer: $1004.4

Step-by-step explanation:

Simple math

The total commission of the employee will be $1004.4 for the given sale.

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.

As per the given,

4.5% of commission on sales.

Total selling = 36 x 620 = $22320

4.5% of $22320 = (4.5/100)22320 = $1004.4

Hence "The total commission of the employee will be $1004.4 for the given sale".

a) The vector equation of the plane with points G, H, and I is (x, y, z) = (2, -5, 3) + s(-1, 2, 1) + t(-6, 11, 0). b) The parametric equations for a plane with LINE 2 and the point (2, -4, 3) are x = 2 - t, y = -4 + 2t, z = 3 - 3t. c) The Cartesian equation of a plane parallel to both LINE 2 and LINE 4 and containing the point (0, 3, -6) is 5x - 7y + 13z - 9 = 0.

a) To find the vector equation of the plane with points G, H, and I, we can use the formula (x, y, z) = (x_0, y_0, z_0) + s(v_1) + t(v_2), where (x_0, y_0, z_0) is a point on the plane, and v_1 and v_2 are vectors in the plane. Substituting the given points G, H, and I, we can obtain the equation.

b) To determine the parametric equations for a plane with LINE 2 and the point (2, -4, 3), we substitute the values from LINE 2 into the general form of the parametric equations (x, y, z) = (x_0, y_0, z_0) + t(v), where (x_0, y_0, z_0) is a point on the plane and v is a vector parallel to the plane.

c) To find the Cartesian equation of a plane parallel to both LINE 2 and LINE 4 and containing the point (0, 3, -6), we can use the equation of a plane in the form Ax + By + Cz + D = 0. The coefficients A, B, C can be determined by taking the cross product of the direction vectors of LINE 2 and LINE 4. Substituting the coordinates of the given point, we can find the value of D.

d) The angle between two planes can be found using the dot product formula. We can calculate the dot product of the normal vectors of A1 and A2 and then use the formula for the angle between vectors.

e) To determine if the point (0, 4, -2) is on A2, we substitute its coordinates into the parametric equations of A2. If the resulting values satisfy the equations, then the point lies on the plane.

f) The distance from a point to a plane can be found using the distance formula. We substitute the coordinates of point G and the coefficients of the equation of A3 into the formula and calculate the distance.

If a current flows at 5 mph. A boat can travel 20 mi downstream in the same amount of time it can go 12 mi upstream. The speed of the boat in still water is 20mph.

Boat speed x mph

Current speed 5 mph

Against current x - 5 mph

With current x + 5 mph

Distance against current 12

Distance with current 20

Time = same equate the time against with time with current

t=d/r

12 /(x- 5)= 20 /(x+ 5)

12 ×(x+ 5 )= 20 ×(x- 5 )

12 x + 60= 20 x -100

12 x -20 x = -100 + -60

-8x = -160

The distance from the point (2, 1) is double it's distance from (1, 2)​ is 2.8

The distance between two points in a 2D Cartesian coordinate system is the length of the path connecting them. The shortest path distance is a straight line. The Pythagorean theorem states that the distance between points (X1, Y1) and (X2, Y2) is given by the formula [(x2 x1)2 + (y2 y1)2], where (x1, y1) and (x2, y2) are two points on the coordinate plane.

Distance = √(y₁-y₂)² + (x₁-x₂)²

distance = √(2-1)² + (1-2)²

the distance = √1+1

Using the center-of-gravity technique, the best site location for the new distribution center in Charlotte is determined to be at coordinates (X, Y) = (27.92, 19.08).

The center-of-gravity technique is used to find the optimal location for a facility based on the distribution of demand. In this case, we will calculate the weighted average of the coordinates (X, Y) of the three sites, with the weights being the number of weekly packages flowing to each site.

To calculate the X-coordinate of the center of gravity, we use the formula:

Xc = (X1 * W1 + X2 * W2 + X3 * W3) / (W1 + W2 + W3)

Similarly, for the Y-coordinate:

Yc = (Y1 * W1 + Y2 * W2 + Y3 * W3) / (W1 + W2 + W3)

Substituting the given values:

Xc = (16 * 26000 + 35 * 12000 + 40 * 10000) / (26000 + 12000 + 10000) ≈ 27.92

Yc = (28 * 26000 + 10 * 12000 + 18 * 10000) / (26000 + 12000 + 10000) ≈ 19.08

Therefore, the best site location for the new distribution center in Charlotte is approximately at coordinates (X, Y) = (27.92, 19.08) based on the center-of-gravity technique.

The number of ways to write n as a sum of two squares is equal to the number of ways to write 2n as a sum of two squares.

To show that the number of different ways to write an integer n as the sum of two squares is the same as the number of ways to write 2n as a sum of two squares, we can use the following identity: (a² + b²)(c² + d²) = (ac + bd)² + (ad - bc)².
Suppose we have two integers, x, and y, such that x² + y² = n. We can use this identity to express 2n as a sum of two squares as follows:
(2x)² + (2y)² = 4(x² + y²) = 2n
Conversely, if we have two integers, a and b, such that a² + b² = 2n, we can express n as a sum of two squares as follows:
(a² + b²)/2 + ((a² + b²)/2 - b²) = (a² + b²)/2 + (a²/2 - b²/2) = (a² + 2b²)/2 = n
Therefore, the number of ways to write n as a sum of two squares is equal to the number of ways to write 2n as a sum of two squares.

Therefore, the future value of a three-year uneven cash flow given below, using an 11% discount rate is $1,238.82.

To calculate the future value of a three-year uneven cash flow given below, using an 11% discount rate, we need to use the formula;

Future value of uneven cash flow = cash flow at year 1/(1+discount rate)¹ + cash flow at year 2/(1+discount rate)² + cash flow at year 3/(1+discount rate)³ + cash flow at year 4/(1+discount rate)⁴

Given the cash flows;

Year 0: $0

Year 1: $600

Year 2: $500

Year 3: $400

Then the Future value of uneven cash flow

= $600/(1+0.11)¹ + $500/(1+0.11)² + $400/(1+0.11)³

= $600/1.11 + $500/1.23 + $400/1.36

=$540.54 + $405.28 + $293.00

=$1,238.82

Answer:

Step-by-step explanation:

To determine the relationship between x and the mean based on the given information, we need to consider the concept of the percentile.

The mean (average) is a measure of central tendency that represents the sum of all values divided by the total number of values. In a normal distribution, the mean is also the 50th percentile.

Given that 72% of the values are less than x, we can conclude that x is greater than the 72nd percentile. Since the mean corresponds to the 50th percentile, x must be larger than the mean.

Therefore, the correct answer is:

c. larger than mean 3

We are given a circle whose diamter is 100 feet. To find out if 140 feet of hedges will fit into it given all the oother dimensions, we will have to calculate the lengths of the chords that correspond to the hedges.

First, let us solve for AE.

We used θ = 50 degrees because we know that the measurement of the arc is equal to the measurement of the central angle.

Now, to solve for the length of ED, we need to find out the measurement of the central angle that subtend it.

Segments AD and EC intersect, thus the following equation must be true for the angles that they form and the arcs that they subtend:

Again, using the formula for finding the length of a chord, we can now solve for the length of ED.

Finally, we need to calculate the length of BC. But we know that BC = ED because the diameters meet at a 90-degree angle and so the chords that they subtend are all congruent. You may also think of ∠BYC as being vertical to ∠EYD. So BC should be equal to ED either way. BC = 100

So the total length of the hedges is:

Therefore, the numbers given by the designers are not reasonable. 140 feet is too short for the hedges.

Step-by-step explanation:

x - 30 = 14 - 3x

    4x = 44

      x = 11

Let's call the unknown number x

Now let's decrease it by 30, that is x-30

Now let's write out "14 decreased by three times the number", that is 14 - 3x

The problem says these are the same, that is x - 30 = 14 - 3x

We now want to isolate, or solve for, x

Move the x to one side of the equation by adding 3x to both sides

3x + x -30 = 14 - 3x + 3x

4x -30 = 14

Now move the 30 to the right hand side by adding 30 to both sides

4x - 30 + 30 = 14 + 30

4x = 44

Now all we have to do to get x is divide both sides by 4

4x/4 = 44/4

x = 11

Dilated triangle Vertex A' = (-42,-22) = (-8,-4),Vertex B' = (02,02) = (0,0), Vertex C' = (-42,42) = (-8,8).

Dilation is a transformation in which a shape is enlarged or reduced by a certain scale factor, while keeping the shape and proportions of the original shape. In the context of triangles, dilation involves multiplying each of the triangle's coordinates by a common scale factor.

When a triangle is dilated, all sides of the triangle are lengthened or shortened by the same scale factor, and all angles of the triangle remain congruent. The vertices of the triangle are moved farther away or closer together, depending on whether the scale factor is greater than or less than 1, respectively.

Dilation is commonly used in geometry to create similar shapes that have different sizes. In real-life applications, dilation can be used to create maps or blueprints at different scales or to resize images while preserving the aspect ratio.

To graph the triangle after a dilation with a scale factor of 2 centered at the origin, we need to multiply the coordinates of the original triangle by 2. The new coordinates will represent the vertices of the dilated triangle.

Original triangle:

Vertex A = (-4,-2)

Vertex B = (0,0)

Vertex C = (-4,4)

Dilated triangle:

Vertex A' = (-42,-22) = (-8,-4)

Vertex B' = (02,02) = (0,0)

Vertex C' = (-42,42) = (-8,8)

It would take the two pumps working together approximately 240 minutes to remove the water.

To determine how long it would take the two pumps to remove the water working together, we can use the concept of work rates. Specifically, we can determine the work rates of each pump and then add them together to find the combined work rate when both pumps are working together.

Let's start by defining some variables:

Let L be the rate of the larger pump, in units of water volume per minute.

Let S be the rate of the smaller pump, in the same units as L.

Let T be the time it takes for both pumps to remove the water working together, in minutes.

From the problem statement, we know that the larger pump can remove all the water alone in 240 minutes. This means that its work rate is 1/240, since it can remove 1 unit of water volume in 240 minutes. Similarly, the smaller pump has a work rate of 1/400.

When both pumps are working together, their work rates add up. Therefore, we can set up an equation as follows:

L + S = 1/T

Substituting the work rates we found earlier, we get:

1/240 + 1/400 = 1/T

Simplifying this equation, we get:

1/T = 0.0041667

Solving for T, we get:

T = 1/0.0041667 ≈ 240.001 minutes
