1. 2x^2+6x=0 <--> 2x(x+3)=0

2.4x-x^2=0 <--> x(4-x)=0

3.14x-7x^2=0 <--> 7x(2-x)=0

4.24x-6x^2=0 <--> 6x(4-x)=0

Step-by-step explanation:

just try to expand the answer given for example when you look at no.1, 2x•x=2x^2 so look for the equation where there is a 2x^2 in it.

for finding the solution, for example when you look at no.1 again, you have 2x=0 so x=0/2=0 and you also have x+3=0 so x=-3

this applies to all the pther no.

Answer:It is 154 square inches. and 38 width

Step-by-step explanation:

Answer:

{5 ft, 18 ft}, {1 ft, 90 ft}, {9 ft, 10 ft}

Step-by-step explanation:

Represent the length and width by L and W respectively.

Then one requirement may be expressed as L > W.

The other requirement is L * W = 90 ft^2.

Let's temporarily replace W in this equation with L:

L^2 = 90 ft^2, so that L must be the positive square root of 90 ft^2:

L = √(90 ft^2) ≈ 9.5

Since L must be greater than W, we can write L > 9.5 ft.  The nearest integer L would be 10, in which case the nearest integer W would be 9, which means that the area of the stage would be 90 ft^2 (as required).

{9 ft, 10 ft} are possible whole number measurements for L and W.  Here W < L, as required, and L and W are both integers.

{5 ft, 18 ft} is another possible set of measurements.

So is {1 ft, 90 ft}.

According to the question, the mean, variation, standard deviation, quartiles, median, and percentile for the given data set are:

Mean = 43.33

Variation = 9646.22

Standard Deviation = 98.21

First Quartile (Q1) = 12

Median = 48

Third Quartile (Q3) = 70

65th Percentile = 50

​

To find the mean, variation, standard deviation, quartiles, median, and percentile for the given data set, we can follow these steps:

Step 1: Sort the data in ascending order: 8, 12, 30, 35, 48, 50, 62, 70, 78.

Step 2: Calculate the mean:

\(Mean = \frac{8 + 12 + 30 + 35 + 48 + 50 + 62 + 70 + 78}{9} = 43.33\) (rounded to two decimal places).

Step 3: Calculate the variation:

\(\text{Variation} = \frac{{\sum((x_i - \text{mean})^2)}}{n}\\\\= \frac{{((8 - 43.33)^2 + (12 - 43.33)^2 + \ldots + (78 - 43.33)^2)}}{9}\\\\= 9646.22 \quad\)

Step 4: Calculate the standard deviation:

Standard Deviation = \(\sqrt{(Variation)} = \sqrt{(9646.22)} = 98.21\) (rounded to two decimal places).

Step 5: Calculate the quartiles:

First Quartile (Q1) = 12 (since it is the median of the lower half of the data).

Third Quartile (Q3) = 70 (since it is the median of the upper half of the data).

Step 6: Calculate the median:

The median is the middle value of the sorted data set, which is 48.

Step 7: Calculate the percentile:

To find the 65th percentile, we need to determine the value that separates the lowest 65% of the data from the highest 35%. Since the data set has 9 elements, 65% of 9 is 5.85. Rounding up, we get 6. The 6th element in the sorted data set is 50, which represents the 65th percentile.

Hence, the mean, variation, standard deviation, quartiles, median, and percentile for the given data set can be represented in LaTeX as follows:

\(\text{Mean} &= 43.33 \\\text{Variation} &= 9646.22 \\\text{Standard Deviation} &= 98.21 \\\text{First Quartile (Q1)} &= 12 \\\text{Median} &= 48 \\\text{Third Quartile (Q3)} &= 70 \\\text{65th Percentile} &= 50 \\\)

In summary: P(z ≥ -1.57) = 0.9394,P(-1.95 ≤ z ≤ 0) = 0.4750,P(z ≤ 2.60) = 0.9953.To find the indicated probabilities, we can use the standard normal distribution table or a calculator.

Here are the calculations:

1. P(z ≥ -1.57):

This represents the probability of z being greater than or equal to -1.57. Using the standard normal distribution table, we can find the corresponding area under the curve. Looking up -1.57 in the table, we find the area to be 0.9394 (or 93.94%).

Therefore, P(z ≥ -1.57) = 0.9394.

2. P(-1.95 ≤ z ≤ 0):

This represents the probability of z being between -1.95 and 0. To find this probability, we need to find the area under the curve between these two z-values. Using the standard normal distribution table, we find the area for -1.95 to be 0.0250 (or 2.50%) and the area for 0 to be 0.5000 (or 50.00%). Subtracting these two values, we get:

P(-1.95 ≤ z ≤ 0) = 0.5000 - 0.0250 = 0.4750 (or 47.50%).

3. P(z ≤ 2.60):

This represents the probability of z being less than or equal to 2.60. Using the standard normal distribution table, we find the area for 2.60 to be 0.9953 (or 99.53%).

Therefore, P(z ≤ 2.60) = 0.9953.

In summary:

P(z ≥ -1.57) = 0.9394

P(-1.95 ≤ z ≤ 0) = 0.4750

P(z ≤ 2.60) = 0.9953

Answer:

C. 190.77

Step-by-step explanation: edge 2022

The required, total cost of the purchase is $190.77. Option C is correct.

The percentage is the ratio of the composition of value to the overall composition of value multiplied by 100.

Here,
To calculate the total cost of the purchase, we first need to calculate the amount of sales tax and add it to the original price.

Sales tax = 7.75% of $175 = 0.0775 x $175 = $13.56

Total cost of purchase = $175 + $13.56 = $188.56

If Susan charges the purchase to her credit card and pays it off after 30 days, she will be charged interest on the outstanding balance for those 30 days. The interest rate is 0.039% per day, which is equivalent to 1.17% per month (0.039% x 30).

The interest charged on the outstanding balance after 30 days will be:

Interest = $188.56 x 1.17% = $2.20

Therefore, the total cost of the purchase, including sales tax and credit card interest, will be,

Total cost = $188.56 + $2.20 = $190.76

Therefore, the total cost of the purchase is $190.77.

The amount of the liquidating dividend is $140,000. A liquidating dividend is a distribution to shareholders that exceeds the company's retained earnings.

Therefore, in order to calculate the liquidating dividend, we need to determine the amount of retained earnings as of January 1, 2018.

Retained earnings = $400,000

The board of directors declared a dividend of $540,000, which is more than the amount of retained earnings. This means that $400,000 of the dividend will be classified as a regular dividend, and the remaining $140,000 will be classified as a liquidating dividend.

The fourth vertex's coordinates are as follows: ( 2.1, -3.6)

A coordinate system in geometry is a method for determining the precise location of points or other geometrical objects on a manifold, such as Euclidean space, using one or more numbers, or coordinates.

So, let the missing coordinates be (a,b).

Let's now utilize the midpoint formula to locate the erroneous coordinate.

Let the reference point be (-2.3, 3.6) A.

Let point B be (2.3, 2.2).

(2.1, 2.2) Let C be the point.

The center of AC should be at BD.

Step 1: Locating the AC's midpoint

Middle pint of AC:

(-2.3 + 2.1/2), (-3.6 + 2.2/2)

(0.2/2), (1.4/2)

(-0.1, -0.7)

Let's equate the midpoints in step two.

The BD mid-point:

(a + -2.3/2), (b + 2.2/2) =  (-0.1, -0.7)

(a + -2.3/2) = -0.1

(a -2.3/2) = -0.1*2

a = -0.2+2.3

a = 2.1

(b + 2.2/2) = -0.7

b + 2.2 = -0.7*2

b + 2.2 = -1.4

b = -1.4 -2.2

The probability that the two chosen segments from the set S have the same length is 4/9.

Given that S be the set of all sides and diagonals of a regular pentagon a pair of elements of S are selected at random without replacement.

We are required to find the probability that the two chosen segments have the same length.

Probability is basically the calculation of likeliness of happening of an event among all the events possible.It lies between 0 and 1.

Probability=Number of items/Total number of items

We can divide this problem majorily into two cases.

Case 1: Side; In this case, there is a 5/10 chance of picking a side, and a 4/9 chance of picking another side.

Case 2: Diagonal; This case is similar to the first, for again, there is a 5/10 chance of picking a diagonal, and a 4/9

Summing all these cases up gives us a probability of 4/9.

Hence the probability that the two chosen segments have the same length is 4/9.

As the diagram shows, we have a triangular face with a base of b = 18 and height of h = 13. The area of this triangular face is:

A = 0.5*b*h

A = 0.5*18*13

A = 117 square cm or cm^2

This represents the area of one face, but there are 4 identical copies of this triangular face assuming this tetrahedron is a regular polyhedron. So we have a total surface area of 4*117 = 468 cm^2 which points us to choice B

The present value of $2,500 per year for 10 years discounted back to the present at 7 percent is $17,462.03.

To calculate the present value of an ordinary annuity, we can use the formula:

PV = A * [1 - (1 + r)^(-n)] / r,

where PV is the present value, A is the annual payment, r is the discount rate per period, and n is the number of periods.

In this case, the annual payment is $2,500, the discount rate is 7 percent (or 0.07 as a decimal), and the number of periods is 10 years. Plugging in these values into the formula, we can calculate the present value:

PV = $2,500 * [1 - (1 + 0.07)^(-10)] / 0.07 ≈ $17,462.03.

Therefore, the present value of $2,500 per year for 10 years discounted back to the present at 7 percent is approximately $17,462.03. This represents the amount of money needed in the present to be equivalent to receiving $2,500 per year for 10 years with a 7 percent discount rate.

Step-by-step explanation:

The value of x will be 48.19°. Then the measure of angle LJK will be 41.81°.

It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.

Triangle LJK is shown.

Angle ∠JLK is a right angle.

The length of the hypotenuse is 15 inches, and the length of the side adjacent to the right angle is 10 inches.

The angle between the 2 sides is x.

Then the measure of the angle x will be given by cosine of x.

cos x = 10 / 15

cos x = 0.667

      x = 48.19°

The value of x will be 48.19°.

We know that the sum of the angle of triangle is 180°.

Then the measure of angle LJK will be

∠LJK + 90° + 48.19° = 180°

Explanation:

The easiest way to think about this is that you have a cone-shaped cake and you are cutting it.

By using the concept of relative velocity, the person will travel 14.5 km over the next 3 hours.

To solve the problem, we will use the concept of relative velocity and we can break it into two parts: the time taken to reach point B and the time taken to travel for the next 3 hours.

Let's start with the time taken to reach point B. We know that the person is moving at a constant speed of 5 km/h and it takes 30 minutes to pass point B. Since speed is distance over time, we can use the formula \($distance = speed \times time$\) to find the distance traveled to reach point B:

\(\[distance_{AB} = 5 \times \frac{1}{2} = 2.5 \text{ km}\]\)

Next, let's calculate the distance the person will travel over the next 3 hours. We know that the person is now moving at a speed of 4 km/h. Again, using the formula \($distance = speed \times time$\), we can find the distance traveled over 3 hours:

\(\[distance_{next3hours} = 4 \times 3 = 12 \text{ km}\]\)

Adding the distance traveled to reach point B and the distance traveled over the next 3 hours:

\(\[total\_distance = distance_{AB} + distance_{next3hours} = 2.5 + 12 = 14.5 \text{ km}\]\)

Therefore, the person will travel 14.5 km over the next 3 hours.

The area bounded by the curve y = 8 − x³ and the x-axis is illustrated below. We need to determine the region's bounds and the integral to solve for the area.We need to determine the x-intercepts of the curve y = 8 − x³. Because the curve passes through the origin, it must have at least one x-intercept.

To find x, we set y = 0, 0 = 8 − x³, x³ = 8, x = 2.

The region is bounded by the curve y = 8 − x³, the x-axis, and the lines x = 0 and x = 2.
