By answering the presented question, we may conclude that If the two graphs are identical, F(x) may polynomials be a valid factorization of G(x), but more study is required to establish this.

A polynomial is a mathematical statement composed of variables and coefficients that be combined using only addition, subtraction, multiplication, and non-negative integer exponents. The phrase 2x3 + 5x2 - 3x + 1 is a polynomial, for example, where x is the variable and the coefficients of the various components are 2, 5, -3, and 1. Polynomials may include one or more variables, but each term must have the same variable (s). The degree of a polynomial is the highest exponent of its variable (s). In the above example, the degree of the polynomial is 3. Polynomials are used in many areas of mathematics, including algebra, calculus, and numerical analysis.

If you believe that one polynomial function is not the right factorization of another, you may use your graphing calculator to confirm this by graphing both functions and comparing their graphs.

Then, in your calculator, insert the polynomial function that you believe is the right factorization. Let us refer to this function as G. (x).

Graph the function G(x) on your calculator by hitting the "graph" button or the equivalent button.

Examine the two graphs. If the two graphs disagree, F(x) does not represent the right factorization of G. (x). If the two graphs are identical, F(x) may still be a valid factorization of G(x), but more study is required to establish this.

Answer:

26.4

Step-by-step explanation:

You can add Y together because they have the same variable making it 10y

The equation is now 10y - 84 = 180

Add 84 to 180 since on the left side it was -84 (Imagine it crossed a magic bridge and become the opposite of what it is)

The equation is now 10y = 264

Divide the equation by 10 because 10 crossed a "magic bridge" to the other side and became division instead of multiplication

The equation is now solved = 26.4

We can cross check this by adding it to the first equation

3(26.4) + 7(26.4) - 84

which gives us 180

Hope this helps

Answer: y=26.4

Step-by-step explanation:

First we need to simplify 3y+7y .... that would be 10y.

Now we have 10y-84=180. We can add 84 to both sides of the equation

So now we have 10y= 180+84 = 10y= 264

Divide both sides by 10= y= 26.4

Now we can check this answer by inputting 26.4 to all the y values in the equation.

(3*26.4) +(7*26.4) - 84=180

79.2 + 184.8 -84=180

180=180    so we know 26.4 is the correct answer

The standard deviation of demand over the lead time is 23.72.

The demand over lead time is normally distributed with a mean of 80. The reorder point for a 95% service level is 119. To calculate the standard deviation of demand over the lead time, we need to use the following formula:

z = (x - μ) / σ, where z is the number of standard deviations from the mean, x is the reorder point for a 95% service level, μ is the mean of the distribution, and σ is the standard deviation of the distribution.

To solve for σ, we need to first find the z-score for a 95% service level, which can be obtained from the standard normal distribution table.

The z-score for a 95% service level is 1.645.

Substituting the given values in the formula, we get:

1.645 = (119 - 80) / σ

Solving for σ, we get:σ = (119 - 80) / 1.645

σ = 23.72

Therefore, the standard deviation of demand over the lead time is 23.72.

The equation for the cost of ticket 13.50 = 1.5m is and the price for a matinee movie ticket is $9.

What is an equation?

A mathematical definition of an equation is a claim that two expressions are equal when they are joined by the equals sign ("=").

Let's use "m" to represent the price of a ticket to a matinee movie.

From the given information, we know that the cost of a ticket to an evening movie is 1.5 times more than a ticket for a matinee movie.

This means that -

Cost of an evening movie ticket = 1.5 × Cost of a matinee movie ticket

We also know that the cost of a ticket to an evening movie is $13.50.

Substituting this value into the equation above, we get -

$13.50 = 1.5m

To solve for "m", we can divide both sides of the equation by 1.5 -

$13.50 / 1.5 = m

m = $9

Answer:

  k = 2/5

Step-by-step explanation:

Given a diagram with triangles ONM and OAB such that M is the midpoint of OB, A lies on AN with AN = 2·OA, and P is the point of intersection of NM and AB, you want the ratio AP/AB.

Please refer to the attached diagram.

Point C is located at the midpoint of AN, which makes OA≅AC≅CN, or AN is 2/3 of ON. Segments AD and CE are parallel to AN, so divide OM into thirds. The length DM is 2 of those thirds, and the length MB is equal to OM, so is 3 of those thirds. That is, the ratio DM/DB is (2/3)/(2/3+3/3) = 2/5.

Triangle BAD is similar to triangle BPM, so the ratio AP/AB is also 2/5.

Answer:

The equation of the ellipse is:

(x^2)/16 + (y^2)/4 = 1

Step-by-step explanation:

An ellipse is a set of points on a plane, the sum of whose distances from two fixed points (called foci) is constant. The distance between the foci of an ellipse is denoted by 2c, and the distance between the center of the ellipse and one of its vertices is denoted by a.

In this problem, the foci are located at (2,0) and (-2,0), so the distance between the foci is 2c = 4, which means that c = 2. The major vertices of the ellipse are located at (4,0) and (-4,0), so the distance between the center and one of the vertices is a = 4.

The formula for the equation of an ellipse centered at the origin is:

(x^2)/(a^2) + (y^2)/(b^2) = 1

where a is the distance from the center to a vertex, and b is the distance from the center to a co-vertex. Since the center of this ellipse is at the origin and the major axis lies on the x-axis, we know that b = a, so we can substitute a for b in the equation:

(x^2)/(a^2) + (y^2)/(a^2) = 1

To find a, we use the fact that c^2 = a^2 - b^2:

a^2 - b^2 = c^2

a^2 - a^2 = 4

b^2 = 4

b = 2

Now we can substitute a = 4 and b = 2 into the equation:

(x^2)/(16) + (y^2)/(4) = 1

This is the equation of the ellipse.

You should invite at least 23 guests to your party to have at least a 2/3 chance of having a guest with the same birthday as yours.

For your party, you need to invite at least 23 randomly chosen guests in order to have a probability of 2/3 or higher of having a guest with the same birthday as yours. This is known as the birthday paradox and it is based on the probability of two people having the same birthday. To calculate the number of guests needed for the probability of having at least one match, you can use the following formula:

P(at least one match) = 1 - (365/365)^n

where n is the number of guests you invite.
So, to solve for n, you would rearrange the equation to:

n = ln(1-P) / ln(365/365)

Thomas can fill 35 of these 1/4 gallon containers with the light-blue mixture.

To find out how many 1/4 gallon containers Thomas can fill with the light-blue mixture, we need to divide the total volume of the mixture by the volume of one container.

The total volume of the mixture can be found by adding the volumes of blue and white paint that Thomas mixed

Total volume = 4 3/8 gallons + 6 5/8 gallons

To add these mixed numbers, we need to find a common denominator, which is 8

Total volume = (4 x 8 + 3) / 8 gallons + (6 x 8 + 5) / 8 gallons

Total volume = 35/8 gallons

Now we can set up the two equations

Total volume = number of containers x volume per container

We know the total volume is 35/8 gallons, and the volume per container is 1/4 gallon, so we can write

35/8 = (1/4) x number of containers

Number of containers = total volume / volume per container

We can rearrange the above equation to solve for the number of containers

Number of containers = total volume / volume per container

Number of containers = 35/8 / 1/4

Number of containers = 35/8 x 4

Number of containers = 35

If f ( x ) = f ( g ( x ) ) , where f ( 5 ) = 7 , f ' ( 5 ) = 5 , f ' ( 0 ) = 3 , g ( 0 ) = 5 , and g ' ( 0 ) = 3 ,f'(0) = 15

We start by using the chain rule to find the derivative of f(x) with respect to x:

f'(x) = f'(g(x)) * g'(x)

Next, we evaluate this equation at x = 0, and use the given values to solve for f'(0):

f'(0) = f'(g(0)) * g'(0)

f'(0) = f'(5) * 3 (since g(0) = 5 and g'(0) = 3)

Now, we need to find f'(5) using the given information. We can start by using the definition of the derivative:

f'(5) = lim h->0 [f(5+h) - f(5)] / h

We know that f(5) = 7, so we can simplify this expression:

f'(5) = lim h->0 [f(5+h) - 7] / h

Using the fact that f(x) = f(g(x)), we can substitute g(x) for x:

f'(5) = lim h->0 [f(g(5+h)) - 7] / h

Now, we can use the mean value theorem to approximate f(g(5+h)):

f'(5) = lim h->0 [f'(g(c)) * g'(5+h)] / 1

where 5 < c < 5 + h. Since f'(5) = 5 and g'(5) = 3, we can simplify this expression:

f'(5) = lim h->0 [5 * 3] / 1 = 15

Therefore, we have found that f'(0) = f'(5) * 3 = 5 * 3 = 15.

Total cost =

We know that Dylan bought himself a cup of tea, which costs less than a cup of coffee. So, the £5.39 must have been spent on buying coffee for his friends.

Let's assume that each cup of coffee costs £1. We can use this assumption to find out how many cups of coffee Dylan bought for his friends:

Number of cups of coffee = total cost ÷ cost per cup of coffee = £5.39 ÷ £1 = 5.39

Since we can't buy a fraction of a cup of coffee, we can round this number down to the nearest whole number. Therefore, Dylan bought 5 cups of coffee for his friends.

We don't have enough information to determine the exact side length of either square A or square C, so we cannot directly calculate their areas. However, we can use the relationship between the areas of the squares to make some conclusions.

Since the area of square B is 64 square units, we know that its side length is √64 = 8 units.

Similarly, since the area of square C is 100 square units, we know that its side length is √100 = 10 units.

Square A is composed of square B and four identical triangles. We know the area of square B is 64 square units, so we need to determine the area of the four triangles to find the area of square A.

Each triangle has a base of 8 units (which is also the length of one side of square B) and a height of half the length of one side of square A. Let's call this length x.

The area of one triangle is (1/2) * 8 * x = 4x square units.

The total area of the four triangles is 4 times the area of one triangle, which is 16x square units.

Therefore, the area of square A is 64 + 16x square units.

We still don't know the exact value of x, but we can make some observations. Since square A is larger than square B, we know that x > 4. And since the triangles make up exactly half of square A (the other half being square B), we know that the area of square A is twice the area of the four triangles. Therefore:

64 + 16x = 2(16x)

64 + 16x = 32x

64 = 16x

x = 4

So the length of each side of square A is 8 + 2x = 16 units, and its area is 64 + 16x = 128 square units.

The length of CA is just the length of one side of square C, which is 10 units.

Answer:

Step-by-step explanation:

We know that Q and P are supplementary because they are parallelograms.

So,

180 - < Q = < P                               Use substitution

180 - 76 = < P                                 Solve

180 - 76 = 104

104 = < P

Since we know that < QPK and < KPS are congruent and are apart of < P we can multiply < P by 1/2 to find either < QPK or < KPS.

So,

1/2(104)                                           Simplify using distributive property

52

If a shape is a triangle, then it’s interior angles all add up to 180.

< KPS + < PKS + < KSP = 180        Use substitutions

52 + 90 + < KSP = 180                  Move variables to one side

< KSP = 180 - 52 - 90                    Simplify  
< KSP = 38

And there’s your answer: 38

Answer:

Let x be the first unknown angle, and y be the second unknown angle.

We know that the sum of the three angles in a triangle is 180 degrees, so:

85 + 9kx + 10kx = 180

where k is a constant representing the ratio of the other two angles.

Simplifying the equation, we get:

19kx = 95

Dividing both sides by 19k, we get:

x = 5/k

Since the ratio of the other two angles is 9:10, we know that:

y = 9kx = 9k(5/k) = 45

So the measures of the two unknown angles are:

x = 5/k and y = 45

We cannot find the exact measures of x and y without more information, but we know that x and y are in a ratio of 9:10 and their sum is 180 - 85 = 95 degrees. We can set up the following equation to solve for k:

5/k + 45/k = 95

50/k = 95

k = 50/95

Using this value of k, we can find the measures of x and y:

x = 5/k = 5/(50/95) = 9.5

y = 9kx = 9(50/95)(9.5) = 47.37

Therefore, the measures of the two unknown angles are x = 9.5 degrees and y = 47.37 degrees (rounded to two decimal places).

To construct a confidence interval for the true average number of alcoholic drinks all UF female students have in a one week period, we can use the following formula

Confidence interval = sample mean ± (critical value) x (standard error)

Where the standard error is calculated as

Standard error = standard deviation / square root of sample size

We are given

Sample size (n) = 170

Sample mean (X) = 4.05

Standard deviation (s) = 4.66

Confidence level = 99%

To find the critical value, we need to look up the t-value with 169 degrees of freedom (since we are using a t-distribution because the sample size is less than 30) and a 99% confidence level. Using a t-distribution table or a calculator, we find the t-value to be approximately 2.62.
