Help me to find two chords.

Answer:

78 square units

Step-by-step explanation:

Length of the rectangle:

Width of the rectangle:

The area of a rectangle can be calculated by multiplying the length by the width.  Therefore, the equation for the area of the rectangle with the given length and width is:

[tex]\begin{aligned}\implies \textsf{Area}&=\sf length \times width\\& = f(x) \cdot g(x)\\&=(x+3)(6x-5)\\&=6x^2-5x+18x-15\\&=6x^2+13x-15\end{aligned}[/tex]

To find the area of the rectangle if x = 3, substitute x = 3 into the found equation:

[tex]\begin{aligned}\implies \textsf{Area}&=6x^2+13x-15\\&=6(3)^2+13(3)-15\\&=6(9)+13(3)-15\\&=54+39-15\\&=93-15\\&=78\;\; \sf square \; units\end{aligned}[/tex]

Therefore, the area of the rectangle is 78 square units.

Solving provided question, we can say that the correlation coefficient for data shown will be as [tex]\sqrt{x} =\sqrt{y} = > \sqrt{x^2} = \sqrt{y^2}[/tex]

In statistics, the Pearson's correlation coefficient, often known as Pearson's r, Pearson's product-moment correlation coefficient, bivariate correlation, or simply correlation coefficient, is a metric for the linear correlation between two data sets. A correlation coefficient is a statistical indicator of how well changes in one variable's value predict changes in another variable's value. The values rise or fall jointly for variables with positive correlation. When evaluating the strength and direction of linear relationships between two sets of variables, correlation coefficients are used. If both variables are regularly distributed, use Pearson's correlation coefficient; if not, use Spearman's.

While reflecting about the line y=x, option (c) [tex]r_{y=x}(x,y) = (y,x)[/tex] is correct and while reflecting about the line y= -x, option (b) [tex]r_{y=-x}(x,y) = (-y,-x)[/tex] is correct.

The x-coordinate and y-coordinate are reversed when a point is reflected over the line y = x. The x-coordinate and the y-coordinate switch places and become negated if you reflect over the line y = -x (the signs are changed). The line y = x is the point of reflection of the point (x,y) across (y, x).

Firstly, the rule for reflecting a point about the line y=x is:

[tex]r_{y=x}(x,y) = (y,x)[/tex]

While reflecting about the line y=x, we get the reflected points by swapping the coordinates.

So, Option 3 is correct.

Now, the rule for reflecting a point about the line y= -x is:

[tex]r_{y=-x}(x,y) = (-y,-x)[/tex]

While reflecting about the line y= -x, we get the reflected points by multiplying '-1'  with the swapped coordinates.

So, Option 2 is correct.

Option G is the correct one. The table represents the non proportional linear relationship with equation y = 3x - 3.

Linear equations are equation involving one or more expressions including variables and constants and the variables are having no exponents or the exponent of the variable is 1.

Linear equations may include one or more variables.

Given values are,

x = 4, then y = 9

x = 5, then y = 12

x = 2, then y = 3

This is clearly not a proportional relation since 4/9 ≠ 5/12

Let y = 3x - 3

If x = 4, then y = (3 × 4) - 3 = 9

If x = 5, then y = (3 × 5) - 3 = 12

If x = 2, then y = (3 × 2) - 3 = 3

This equation holds.

Hence the true statement is option G.

Step-by-step explanation:

All exponential functions go through the point (0,1) because the value of x when it equals to 0, in the general form of exponential function f(x) = [tex]a^x[/tex], results in [tex]a^0[/tex] = 1, which is why all exponential functions have the point (0,1) on their graph.

All exponential functions go through the point (0,1) because of the properties of exponential functions. The general form of an exponential function is f(x) = [tex]a^x[/tex], where a is a positive constant. When x = 0, the function evaluates to [tex]a^0[/tex] = 1, which is why all exponential functions have the point (0,1) on their graph.

Another way to understand this is that the exponential function is defined as the function that describes how a quantity grows or decays at a fixed percentage rate over time. The function f(x) = [tex]a^x[/tex], where a is a constant greater than 0 and less than 1, describes the decay of a quantity over time. For example, if the interest rate is 10%, the value of a = 0.1 and the function f(x) = [tex]0.1^x[/tex]. When x = 0, the function evaluates to [tex]0.1^0[/tex] = 1, which means that the initial value of the quantity is 1.

It's important to note that the point (0,1) is called the y-intercept, and it is a special point in the graph of exponential functions, and it's always present in the graph of exponential functions.

The volume of air in the spherical ball is [tex]\frac{4}{3}\cdot \pi\cdot 3^3\cdot 10^6[/tex]. So the option A is correct.

In the given question, we have to find the volume of air in the spherical ball.

A sphere's capacity is measured by its volume. It is the area the sphere calls home. Cubic units are used to express the volume of a sphere. The sphere has a three-dimensional, rounded shape. Its shape is defined by its three axes, which are the x, y, and z axes.

Since the cross-section of the sphere is a circle, the volume in this situation is dependent on the radius's diameter. A sphere's surface area is the area or region of its outside. The following formula can be used to determine the volume of a sphere whose radius is "r":

V = [tex]\frac{4}{3}\pi r^{3}[/tex]

As given r = 3·10^2. So,

V = [tex]\frac{4}{3}\pi (3\cdot 10^2)^{3}[/tex]

V = [tex]\frac{4}{3}\cdot \pi\cdot 3^3\cdot 10^6[/tex]

V = [tex]4\cdot \pi\cdot 3^2\cdot 10^6[/tex] cm^3

Hence, the option A is correct.

Finding the coordinates of an object in an image involves using image processing techniques such as object detection and image segmentation.

Object detection involves identifying the presence of an object in an image, while image segmentation involves isolating the object in the image.

Once the object is identified and isolated, its coordinates can be determined by using the position of the object's bounding box or contour.

Bounding box is a rectangular box that surrounds the object, its coordinates can be determined by the position of its top-left corner and bottom-right corner.

Contour is the boundary of the object, its coordinates can be determined by the points that are part of the boundary.

Computer Vision libraries such as OpenCV, Tensorflow or PyTorch can be used to perform object detection and image segmentation. They also provide pre-trained models which can be used for object detection and image segmentation without the need to train a model from scratch.

In conclusion, finding the coordinates of an object in an image requires using image processing techniques such as object detection and image segmentation to identify and isolate the object, and then determining its coordinates by using the position of the object's bounding box or contour.

This process can be aided by using Computer Vision libraries such as OpenCV, Tensorflow or PyTorch.

The amount of money Company B charge for x miles than Company A when Company A charges $35.50 and 11cent per mile. Company B charges $60.50 and 12cent per mile is $40 and 1 x cents.

The concept that will be used is the concept of substraction and unit conversion.

Company A  =$35.50 and 11 cent per mile

Company B  =  $60.50 and 12 cent per mile

(Amount of money from Company B -Amount of money from Company A)

($75.50 and 12 cent - $35.50 and 11 cent )

= $40.00 and 1 cents per mile.

Then to know the amount the Company B charge for x miles than Company A which is  x miles, we multiply $40.00 and 1 cents by x miles.

A polynomial f(x) has a factor (x-a) if and only if f(a) = 0, according to the factor theorem. It's one of the techniques for factoring a polynomial.

Since, the response above already covered the theorem's formulation.

Here, we shall demonstrate the factor theorem formula, which allows us to factor the polynomial.

When the polynomial f(x) is divided by (x-c), f(c) equals 0.

Remainder Theorem demonstrates that f(x)=(x-c)q(x)+f (c)

where the quotient polynomial is q(x) and the target polynomial is f(x).

Because f(c) = 0, f(x) = (x-c)q(x)+f (c)

(x-c)q(x)+0 f(x) = (x-c)q (x)

Therefore, the polynomial f's factor (x-c) exists (x).

The probability of A or B would be 0.3269. Probability can be used to make predictions and make decisions based on uncertain information in fields such as finance, engineering, and science.

Probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1, with 0 indicating that an event will not occur and 1 indicating that an event will definitely occur. Events with probabilities closer to 1 are considered more likely to happen, while events with probabilities closer to 0 are considered less likely.

Since A and B are mutually exclusive events, they cannot occur at the same time. Therefore, the probability of A or B is the sum of their individual probabilities.

p(A or B) = p(A) + p(B) = 0.07692 + 0.25 = 0.32692

To four decimal places, the probability of A or B is 0.3269.
