The value of x and y at which function P = 3x+2y becomes maximum are

(9,0), data from given graph.

What is the graph?

Graph is the pictorial representation of given data.

Graph is defined as to create a diagram that shows a relationship between two or more things. An example of graph is to create a series of bars on graphing paper.

The four most common are

1. Probably line graphs,

2. Bar graphs and histograms,

3. Pie charts, and

4. Cartesian graphs

To find the maximum, input the vertices (0,8), (5,4) and (9,0) into the objective function (P = 3x + 2y) to determine which vertex obtains the maximum value.

Note: (5,4) is not a vertex.

(0,8) :

P = 3*0 + 2*8

  = 16

(5,4):
P = 3*5 + 2*4

  = 23

(9,0):

P = 3*9 + 2*0

  = 27.

So, the maximum value = 27 at (9,0).

So, the x value = 9 and

      the y value = 0.

Answer:

The perimeter is approximately 6.40.

Step-by-step explanation:

To find the perimeter of a triangle with vertices X (1, 3), Y (-4, -1), and Z (4, -1), we can first find the distance between each pair of points using the distance formula.The distance between points X and Y is:

$d(X,Y) = \sqrt{((1 - (-4))^2 + (3 - (-1))^2)} = \sqrt{25 + 16} = \sqrt{41}$

The distance between points Y and Z is:$d(Y,Z) =

\sqrt{((-4 - 4)^2 + ((-1) - (-1))^2)} = \sqrt{0 + 0} = 0$

The distance between points X and Z is:

$d(X,Z) = \sqrt{((1 - 4)^2 + (3 - (-1))^2)} = \sqrt{9 + 16} = \sqrt{25}$

We can then find the perimeter of the triangle by adding up the lengths of the sides. In this case, the perimeter is $d(X,Y) + d(Y,Z) + d(X,Z) = \sqrt{41} + 0 + \sqrt{25} = \sqrt{41} + \sqrt{25} = 6.40\ldots$.

Rounded to two decimal places, the perimeter is approximately 6.40.

What is unitary method?

The unitary approach is a strategy for problem-solving that involves first determining the value of a single unit, then multiplying that value to determine the required value. Finding the value of a single unit using the unitary technique, then extrapolating from this value.

Given that,

Emma grew 6 plants with 3 seed packets.

To grow 6 plants Emma needs 3 seed packets.

Applying unitary method:

To grow 1 plants Emma needs 3/6 seed packets.

To grow 16plants Emma needs (3 × 16)/6 seed packets.

                                                   = 8 seed packets.

The probability that we will draw 4 kings from the 52-card deck be 1/270725.

Given, we draw 4 cards from a standard 52-card deck

we have to find the probability that we draw 4 kings

As, we know that the deck of cards contain 4 kings of two red and two black.

we have to choose 4 kings from 4 kings in the deck

Number of ways to choose 4 kings from the deck of cards =  C(4 , 4)

Now, total number of ways in which 4 cards can be chosen be,

C(52 , 4)

So, the probability of drawing 4 kings from the deck of cards be,

P(E) = C(4 , 4)/C(52 , 4)

P(E) = 4×3×2 / 52×51×50×49

P(E) = 1 / 13×17×25×49

P(E) = 1/270725

There are 12 different positive two digit integers can be formed using these digits if a digit can be repeated in an integer.

Integer:

An integer is zero (0), a positive integer (1, 2, 3, etc.), or a negative integer with a minus sign (-1, -2, -3, etc.). A negative number is the additive reciprocal of the corresponding positive number. In mathematics languages, sets of integers are often denoted by a bold Z or a bold {Z}.

Given the question :

The number of different positive two integer number can be obtained by:

P(4, 2) = 4P2

We know that:

[tex]^nP_r[/tex] = n! / (n - r)!

⁴P₂ = 4! / (4 - 2)!

⁴P₂ = 4! / 2!

⁴P₂ = (4 * 3 * 2 * 1) / ( 2 * 1)

The quadratic equation with the given x-intercepts and that passes through the point (1, 192) is the one in option D.

y = -8x^2 -64x + 264

If a quadratic equation has x-intercepts x₁ and x₂ and a leading coefficient a, we can write the quadratic equation as:

y = a*(x - x₁)*(x - x₂)

Here we know that the x-intercepts are -11 and 3, replacing that in the equation above we will get:

y = a*(x + 11)*(x - 3)

We also know that the line passes through the point (1, 192), replacing the values in the quadratic equation we will get:

192 = a*(1 + 11)*(1 - 3)

192 = a*12*-2

192 = -24*a

192/-24 = a

-8 = a

So the quadratic equation is:

y = -8*(x + 11)*(x - 3)

Expanding this, we will get:

y = -8x^2 -64x + 264

Also, we have the following equation

x = 2y - 78 --- by the theorem of corresponding angles

Substitute x = 2y - 78  in x = 5y

So, we have the following representation

5y = 2y - 78

Evaluate the like terms

3y = 78

Step-by-step explanation:

The equation of the line, in slope-intercept form,  that passes through the given points, (6,-4) and (6,5) is: x = 6.

An vertical line can be written in slope-intercept form as x = a, because the line has no y-intercept and the change in x values in the slope formula is equal to zero.

The value of a in the equation is the point on the x-axis where the vertical line intercept, irrespective of the change in y-values up the line.

Given the line goes through the points, (6, -4) and (6, 5), it means the line is a horizontal line because they both have the same x-value, 6.

Therefore, the value of a is 6. The equation of the line would be x = 6.

The scale factor from B to A is 5/8. Since the scale-up and scale-down of A and B are reciprocal to each other. I.e, scaling of geometry can be reversed by the reciprocal of its scale factor.

The scale factor for the given shape to transform from A to B is 8/5.

So, the original shape is A and it is scaled up by the factor 8/5 and named B.

(Scaled up since scale factor (8/5 = 1.6) > 1)

So, the scaling from B to A is the reverse process of scale-up. That means scale-down. For this, the scale factor is reduced by taking its reciprocal. So, that the shape gets reversed.

The scale factor for scaling down from B to A is 1/(8/5) ⇒ 5/8.

Step-by-step explanation:

To find the ratio of the number of female runners to the total number of runners, we can divide the number of female runners by the total number of runners and express the result as a fraction. There are 25 female runners, and there are a total of 24 men + 25 women = 49 runners. Therefore, the ratio of the number of female runners to the total number of runners is 25/49. This fraction can be reduced to 5/9.

The radii of the cylinders found using the formular for the volume of a cylinder, and the 2009.6 cubic centimeter and 196.25 cubic centimeter volumes of the cylinders, indicates;

The radius of the 2009.6 cm³ cylinder is 8 centimeters

The radius of the 196.25 cm³ cylinder is 2.5 centimeters

A cylinder is a solid that has three dimensions, consisting of two circular, parallel bases that enclose a curved pipe like surface in between.

The volume of one cylinder = 2009.6 cubic centimeters

The volume of the other cylinder = 196.25 cubic centimeters

The height of each cylinder, h = 10 centimeters

The formula for finding the volume of a cylinder is; V = π·r²·h

Where;

r = The radius of the cylinder

h = The height of the cylinder

The formula for finding the volume of a cylinder indicates;

r² = V/(π·h)

r = √(V/(π·h))

The radius of the cylinder of volume 2009.6 cubic centimeters, r₁ is therefore;

r = √(2009.6/(3.14 × 10) = 8

The radius of the 2009.6 cubic centimeters volume cylinder is r₁ = 8 cm

The radius, of the 196.25 cubic centimeters cylinder, r₂, is therefore;

The total cost of the meal plus tip and tax was more than 122% of the cost of the bill.

What is percent?

A percentage in mathematics is a number or ratio that is expressed as a fraction of 100. The abbreviations "pct.", "pct.", and occasionally "pc" are also used to indicate it, though the percent sign, "%," is most frequently used. A percentage has no dimensions and no standard measurement.

Indigo goes out to lunch.

The bill, before tax and tip, was $10.85.

A sales tax of 3% was added on.

Indigo tipped 18% on the amount after the sales tax was added.

The amount after adding sales tax is,

$10.85 x 3% = 0.3255

⇒ $10.85 + 0.3255 = $11.1755

Now to find the amount after tipped 18% on the amount after the sales tax was added.

$11.1755 x 18% = 2.01159

⇒ $11.1755 + 2.01159 = $13.18709

Hence, the amount  after tipped 18% on the amount after the sales tax was added is $13.18709.

Let x be the percent of more than the cost of the bill of $13.18709.

⇒

[tex]\frac{10.85(x)}{100} = 13.18709\\ x = \frac{100 (13.18709)}{10.85}\\ x = 121.54[/tex]
