Answer:

\(x + y = 3325 \\ i \:hope \: it \: helps\)

=====================================================

Explanation:

I'm assuming you meant to write $10,600 instead of $10,6000.

We'll replace y with this value and solve for x.

\(y=10,000+50x-x^2\\\\10,600=10,000+50x-x^2\\\\0=10,000+50x-x^2-10,600\\\\-x^2+50x-600 = 0\)

Use the quadratic formula with a = -1, b = 50, c = -600

\(x = \frac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\x = \frac{-50\pm\sqrt{(50)^2-4(-1)(-600)}}{2(-1)}\\\\x = \frac{-50\pm\sqrt{100}}{-2}\\\\x = \frac{-50\pm10}{-2}\\\\x = \frac{-50+10}{-2} \ \text{ or } \ x = \frac{-50-10}{-2}\\\\x = \frac{-40}{-2} \ \text{ or } \ x = \frac{-60}{-2}\\\\x = 20 \ \text{ or } \ x = 30\\\\\)

We go for the smaller x value because the question asks "what is the least amount she can raise the price?".

If she raises the price by $20, then she would estimate to make about $10,600.

Answer:

I am not sure if my math is correct but I got $15 dollars in change.

Step-by-step explanation:

$50 times 0.10 (10%) equals $5. $50.00 minus $30.00 is $20.00. $20 minus $5 is $15.

Based on the formulas given, the slope and the y intercepts are:

15. m = 1; b = 5

16. m = 1.5; b = 2

17. m = -2; b = 2

18. m = 1; b = 2

A linear expression takes the form:

y = mx + b

m = slope

b = y-intercept

15. y - 4 = x + 1

y = x + 1 +4

y = x + 5

m = 1

b = 5

16. 2y + 1 = 3x + 5

2y = 3x + 4

(2y = 3x + 4) / 2

y = 1.5x + 2

m = 1.5

b = 2

17. 2(x - 1) = -y

y = -2x + 2

m = -2

b = 2

18. 2y - 4 = 2x

2y = 2x + 4

(2y = 2x + 4) / 2

y = x + 2

m = 1

b = 2

The form of the partial fraction decomposition of the given functions are: Partial fraction decomposition

x² + x + 12(ax + b) / (x² + x + 12)x⁴ + 1 / ((25 + 623³)) [Ax + B]/ (x² + 1) + [Cx + D] / (x² - 1)(x² – 9)² [A / (x - 9)] + [B / (x - 9)²] + [C / (x + 9)] + [D / (x + 9)²]

Given function is x² + x + 12, we are to write out the form of the partial fraction decomposition of the function and not to determine the numerical values of the coefficients.

Partial fraction decomposition of the given function x² + x + 12 is:  

x² + x + 12 = (ax + b) / (x² + x + 12)

Where a and b are constants.

We are also given another function which is:

(a) X⁴ +1 25 + 623 3

To write out the form of the partial fraction decomposition of the function, it is important to factorize the denominator of the function in order to determine the form of the partial fraction decomposition.

The factors of x⁴ + 1 can be obtained as: (x² + 1)(x² - 1) = (x² + 1)(x + 1)(x - 1)

Therefore, the partial fraction decomposition of x⁴ + 1 / ((25 + 623³) is given as:

(x⁴ + 1) / ((25 + 623³)) = [Ax + B]/ (x² + 1) + [Cx + D] / (x² - 1)(b) (x² – 9)²

To write out the form of the partial fraction decomposition of the function, we will consider the factors of the denominator.

The factors of (x² - 9)² can be obtained as:

(x - 9)² (x + 9)²

Therefore, the partial fraction decomposition of (x² – 9)² is given as:

(x² – 9)² = [A / (x - 9)] + [B / (x - 9)²] + [C / (x + 9)] + [D / (x + 9)²]

(a) x² + x + 12

Partial fraction decomposition is the process of expressing a fraction that contains a polynomial of the numerator and a polynomial of the denominator as the sum of two or more fractions with simpler denominators. By using partial fraction decomposition, it is possible to integrate many rational functions.To write out the form of the partial fraction decomposition of the function x² + x + 12, first, we need to factorize the denominator. In this case, we cannot factorize x² + x + 12 into linear factors with real coefficients. Therefore, the partial fraction decomposition does not exist, and the answer is DNE.(b) (x² – 9)²We can factorize the denominator of (x² – 9)² to obtain\((x² – 9)² = (x + 3)²(x – 3)²\)Now, we can express the function as(x² – 9)² = (A / x + 3) + (B / (x + 3)²) + (C / x – 3) + (D / (x – 3)²)By solving for the constants A, B, C, and D, we can obtain the numerical values of the coefficients.

Answer: See explanation

Step-by-step explanation:

Let the price per pound of coffee be c

Let the price ce per pound of butter be b.

We can form an equation based on the information given and this will be:

2c + b = 11.25 ....... i

3c + 2b = 18.50 ....... ii

From equation i, b = 11.25 - 2c ..... iii

Put the value of b into equation ii.

3c + 2b = 18.50

3c + 2(11.25 - 2c) = 18.50

3c + 22.50 - 4c = 18.50

-c = 18.50 - 22.50

c = 4.00

A pound of coffee cost $4.00

Since b = 11.25 - 2c .

b = 11.25 - 2(4.00)

b = 11.25 - 8.00

b = 3.25

A pound of butter costs $3.25

Answer:

please the question is not complete oo

Answer:

Step-by-step explanation:

To work out the profit as a percentage of the cost price, you can use the following formula:Profit percentage = (Profit / Cost price) x 100%For example, if you bought an item for $50 and sold it for $70, the profit would be $20. To find the profit as a percentage of the cost price, you would use the formula above:Profit percentage = (20 / 50) x 100% = 40%So in this example, the profit as a percentage of the cost price is 40%.To find the best value of a price, you need to consider both the cost and the demand for the item. If the price is too high, people may not be willing to buy it, but if it's too low, you may not make enough profit. The best value is the price that maximizes your profit while still attracting enough customers to make sales.One way to determine the best value is to experiment with different prices and see how they affect sales and profits. You can start with a price that you think is reasonable and then adjust it up or down based on customer feedback and sales data. You can also research the prices of similar items sold by competitors to get an idea of what the market will bear.Ultimately, the best value will depend on factors such as the cost of production, the demand for the item, and the competitive landscape. It's important to find a price that balances all of these factors to maximize your profits and grow your business.

The order of every element in (Z18, +) is as follows:

Order 1: 0

Order 3: 6, 12

Order 6: 3, 9, 15

Order 9: 2, 4, 8, 10, 14, 16

Order 18: 1, 5, 7, 11, 13, 17

The set (Z18, +) represents the additive group of integers modulo 18. In this group, the order of an element refers to the smallest positive integer n such that n times the element yields the identity element (0). Let's find the order of every element in (Z18, +):

Element 0: The identity element in any group has an order of 1 since multiplying it by any integer will result in the identity itself. Thus, the order of 0 is 1.

Elements 1, 5, 7, 11, 13, 17: These elements have an order of 18 since multiplying them by any integer from 1 to 18 will eventually yield 0. For example, 1 * 18 ≡ 0 (mod 18).

Elements 2, 4, 8, 10, 14, 16: These elements have an order of 9. We can see that multiplying them by 9 will yield 0. For example, 2 * 9 ≡ 0 (mod 18).

Elements 3, 9, 15: These elements have an order of 6. Multiplying them by 6 will yield 0. For example, 3 * 6 ≡ 0 (mod 18).

Elements 6, 12: These elements have an order of 3. Multiplying them by 3 will yield 0. For example, 6 * 3 ≡ 0 (mod 18).

Answer:

If you click on the link you find a picture which has black dots on a white background. This suggests that we color every point on the plane either white or black, making sure to use infinitely many of each color. With these constraints it is indeed the case that there must be a black point and a white point at unit distance. (In fact, "infinite" can be weakened to nonempty.)

Step-by-step explanation:

Hint: starting with a black point, we're done unless the entire unit circle around that point is black. Now repeat that argument for each point on that unit circle: we've already generated a sizable swathe of the plane colored totally black...

Answer:

15 ft

Step-by-step explanation:

This is another classic case of Pythagoras theorem. To start with, let's assume that the length of the ladder we're looking for is x

We're told that the height of the building the ladder is leaning on is, x - 3

Also we're told that the distance at an adjacent from the ladder is 9 ft.

If we use Pythagoras theorem, we have

x² = (x - 3)² + 9²

x² = x² - 6x + 9 + 81

On rearranging, we have

x² - x² = -6x + 90

6x = 90

x = 90 / 6

x = 15 ft

Therefore, the length of the ladder is found to be 15 ft

Answer:

SA = 94 ft²

Step-by-step explanation:

To find the surface area of a rectangular prism, you can use the equation:

SA = 2 ( wl + hl + hw )

SA = surface area of rectangular prism

l = length

w = width

h = height

In the image, we are given the following information:

l = 4

w = 5

h = 3

Now, let's plug in the information given to us to solve for surface area:

SA = 2 ( wl + hl + hw)

SA = 2 ( 5(4) + 3(4) + 3(5) )

SA = 2 ( 20 + 12 + 15 )

SA = 2 ( 47 )

SA = 94 ft²

The statements that are true about a sine function of the form y = a sin(k(x - d)) + c are:

The ∣a∣ is the amplitude of the function: The absolute value of 'a' represents the amplitude of the function, which is the maximum displacement from the average value or midline.

The values of d and c determine the horizontal and vertical translations, respectively: The value of 'd' determines the horizontal shift or phase shift of the function, while 'c' determines the vertical shift or vertical translation of the graph.

The value of k represents the period of the function: The value of 'k' affects the period of the function. The period is the distance between two consecutive peaks or troughs of the sine function, and it is inversely proportional to 'k'. A larger value of 'k' corresponds to a shorter period.

y = c is the equation of the axis: The value of 'c' represents the vertical translation or shift of the graph. The equation y = c represents the horizontal line (axis) around which the sine function oscillates.

The statements that are not true are:

The values of a and k are vertical and horizontal stretches: The values of 'a' and 'k' do not represent vertical or horizontal stretches. Instead, 'a' represents the amplitude, and 'k' affects the period of the function.

The values of a and c affect the range of the function: The values of 'a' and 'c' do not affect the range of the function. The range of the sine function is determined by the amplitude 'a' and the vertical shift 'c'.

The correct value for the integral , ∫[3, 6] (3/1) dx = 9.

To compute the integral ∫[3, 6] (3/1) dx, we integrate the given density function over the interval [3, 6].

∫[3, 6] (3/1) dx = 3 ∫[3, 6] dx

Integrating the constant function 1 with respect to x gives:

3 ∫[3, 6] dx = 3(x) ∣[3, 6] = 3(6) - 3(3) = 18 - 9 = 9

Therefore, ∫[3, 6] (3/1) dx = 9.

Given the density function f(x) = 3/1, we want to calculate the integral of this function over the interval [3, 6].

The integral is represented as ∫[3, 6] (3/1) dx, where the symbol ∫ represents integration, [3, 6] denotes the interval of integration, (3/1) is the integrand (the function being integrated), and dx represents the differential variable.

To evaluate the integral, we integrate the constant function (3/1) with respect to x. Integrating a constant results in a linear function.

Integrating the constant (3/1) with respect to x gives:

∫(3/1) dx = (3/1) ∫ dx

The integral of dx is simply x. Applying the integration bounds, we get:

(3/1) ∫[3, 6] dx = (3/1) (x) ∣[3, 6]

Evaluating the expression at the upper and lower bounds of integration, we have:

(3/1) (x) ∣[3, 6] = 3(6) - 3(3) = 18 - 9 = 9

So, the result of the integral ∫[3, 6] (3/1) dx is equal to 9.
