(5) + 2 = 7

2(5) + 3 = 13

13 * 7 = 91

Step-by-step explanation:

Given area = 91m²

length = 2x+3 m

breadth = x +2 m

we know,

Area = length x breadth

91 = (2x+3) x (x+2)

91 = 2x² + 4x + 3x + 6

91 = 2x² + 7x + 6

2x² + 7x - 85 = 0

(2x+17)(x−5)=0

2x+17=0 or x−5=0

x=−17/2 or x=5

The value of x in the given equation is 6.4. The solution is obtained by solving the linear equation.

What is a linear equation?

A linear equation is the equation which has the highest degree as 1. This shows that a linear equation with an exponent greater than one has no variables. On the graph, such an equation results in a straight line.

We are given \(\frac{3}{4} (\frac{x}{4} +8) - (\frac{x}{2} +2)=\frac{3}{8} (4-x) - \frac{x}{4}\)

Now, let's simplify the linear equation

⇒\(\frac{3x}{16} + 6 - \frac{x}{2} -2= 6 - \frac{3x}{8} - \frac{x}{4}\)

Now, on combining the like terms, we get

⇒\(\frac{3x}{16} - \frac{x}{2} +\frac{3x}{8} + \frac{x}{4} = 2\)

⇒\(\frac{3x-8x+6x+4x}{16} = 2\)

⇒\(\frac{5x}{16} = 2\)

⇒ 5x = 32

⇒ x = 6.4

Hence, the value of x in the given equation is 6.4.

The number of people in the set C ∩ D (customers who purchased both cats and dogs) is obtained by adding the overlap of D and C (3) with the overlap of all 3 circles (1), resulting in a total of 4 individuals.

The correct answer is 4.

To determine the number of people in the set C ∩ D (customers who have purchased both cats and dogs), we need to analyze the overlapping regions in the Venn diagram.

Given information:

- Circle C (cats): 15

- Circle D (dogs): 21

- Circle F (fish): 12

- Overlap of C and F: 2

- Overlap of F and D: 0

- Overlap of D and C: 3

- Overlap of all 3 circles: 1

- Number outside of circles: 14

To determine the number of people in the set C ∩ D (customers who have purchased both cats and dogs), we need to consider the overlapping region between circles C and D.

From the information given, we know that the overlap of D and C is 3. Additionally, we have the overlap of all 3 circles, which is 1. The overlap of all 3 circles includes the region where customers have purchased cats, dogs, and fish.

To calculate the number of people in the set C ∩ D, we add the overlap of D and C (3) to the overlap of all 3 circles (1). This gives us 3 + 1 = 4.

Answer and Step-by-step explanation: Rotation is a "movement" of a geometric figure in order to transform one in another. In rotation, the shape and size of the figure is the same, so they are congruent.

A geometric figure can be rotated clockwise or counterclockwise and by different angles.

One way to recognized the angle of rotation is comparing the points of the figure and its rotated image.

On the figure below, triangle DOG has coordinates:

D (-2,1)

O (-3,3)

G (1,1)

And its image:

D' (2,-1)

O' (3,-3)

G' (-1,-1)

Comparing both set of coordinates, we observe:

D (-2,1) → D' (2,-1)

O (-3,3) → O' (3,-3)

G (1,1) → G' (-1,-1)

that the coordinates for ΔDOG and ΔD'O'G' are opposite to each other, i.e.:

(x, y) → (-x,-y)

rotating counterclockwise.

Since coordinates are opposite and rotation is counterclockwise, ΔD'O'G' is rotated by 180° related to ΔDOG.

Step-by-step explanation:

The formula for y in terms of x is y=160​/x^2.

We are given that;

y = 20 when t=4

And t = 8 when x = 2

Now,

To find the value of k by using the fact that y = 20 when t = 4:

20=k⋅4

k=5

Also, y=5t

Next, we use the fact that t is inversely proportional to the square of x. We can write:

t=x2k​

where k is a constant of proportionality. We can find the value of k by using the fact that t = 8 when x = 2:

8=22k​

k=32

Now we know that:

t=x232​

Substituting this into the equation for y:

y=5t=5⋅x232​=160​/x^2

Therefore, by proportions the answer will be y=160​/x^2.

Answer:

-3/4

Step-by-step explanation:

So you have the equation: \(y=\frac{4}{3}x-\frac{5}{3}\). For a perpendicular line, the only thing that matters is the slope. The slope of the perpendicular line can be defined as: \(\frac{a}{b} = > -\frac{b}{a}\). It's the reciprocal with the sign being the opposite. So if the sign of the original line was negative it's now positive, and if it's positive, it's not negative. The fraction is also flipped, even if it's an integer, it can be defined as a fraction e.g (\(6 = > -\frac{1}{6}\) (sign also changed too))

So in this case the slope is 4/3x, since it's given in slope-intercept form: y=mx+b where m is the slope and b is the y-intercept. So we flip it to get 3/4 and change the sign to negative to get -3/4

Dimension of smaller garden :

l = 1/2 ft.

b = 2/3 ft.

Dimension of bigger garden :

L = 4 ft.

Let , breadth be x ft.

We know , area is given by :

Area = L×B.

Area of small garden = \(\dfrac{1}{2}\times\dfrac{2}{3}=\dfrac{1}{3}\ ft^2\)

Area of big garden \(=4\times x=4x\ ft^2\)

Hence, this is the required solution.

Note that as x gets larger, y gets smaller, but the product xy remains constant at 192.

In mathematics, a function is a relationship between two sets, called the domain and the range, such that each element of the domain corresponds to exactly one element of the range. A function takes an input value (or values) and produces an output value (or values) according to a specific rule or formula. The input values are the domain of the function, and the output values are the range of the function. Functions can be represented using equations, graphs, tables, or verbal descriptions. They are used to model relationships between variables in various fields of mathematics, science, engineering, economics, and many other areas.

Here,

If x and y vary inversely, this means that their product is a constant. We can use this fact to find the constant of proportionality k as follows:

k = xy

If we know that y is 24 when x is 8, we can substitute these values into the equation above to solve for k:

k = xy

= 8(24)

= 192

Now we can use this value of k to write the inverse variation function:

xy = 192

or

y = 192/x

To sketch a graph of this function for x > 0, we can plot a few points and connect them with a smooth curve. Here are some points we can use:

(x, y)

(2, 96)

(4, 48)

Yes, there is a difference in the shapes of the displacement-time graphs for uniform acceleration towards the positive direction, uniform acceleration towards the negative direction, uniform deceleration towards the positive direction, and uniform deceleration towards the negative direction.

Uniform acceleration towards the positive direction:

In this case, the object's velocity increases in the positive direction over time. The displacement-time graph will have a concave-upward shape, forming a curve that starts with a small slope and gradually becomes steeper as time progresses.

Uniform acceleration towards the negative direction:

Here, the object's velocity increases in the negative direction, meaning it accelerates in the opposite direction to its positive direction.

The displacement-time graph will have a concave-downward shape, forming a curve that starts with a steep slope and gradually becomes less steep as time progresses.

Uniform deceleration towards the positive direction:

In this scenario, the object's velocity decreases in the positive direction, but it still moves towards the positive direction.

The displacement-time graph will show a curve with a decreasing slope, forming a concave-downward shape, indicating that the object is slowing down.

Uniform deceleration towards the negative direction:

Here, the object's velocity decreases in the negative direction, opposing its initial direction.

The displacement-time graph will have a curve with a decreasing slope, forming a concave-upward shape, indicating that the object is slowing down but still moving in the negative direction.

In summary, the shapes of the displacement-time graphs differ based on the direction and type of acceleration (positive or negative) and whether the object is undergoing uniform acceleration or uniform deceleration. These differences can be observed through the concavity and slope of the graphs.

Step-by-step explanation:

The general form of the equation for a circle centered at the origin (0, 0) is x^2 + y^2 = r^2, where r is the radius of the circle. The radius can be calculated as the distance between the center O (0, 0) and point B (4, 5) on its circumference using the distance formula: r = sqrt((x2 - x1)^2 + (y2 - y1)^2) = sqrt((4 - 0)^2 + (5 - 0)^2) = sqrt(16 + 25) = sqrt(41). Therefore, the equation for the given circle centered at O (0, 0) is x^2 + y^2 = 41. The correct answer is B. x^2 + y^2 − 41 = 0.
