The two points that could be used to plot the graph of the function (0, -0.4) and (-0.874, 0)

In this question, we have been given a function f(x) = (3x³ + 2)/(x^2-5).

We need to plot the graph of the function.

We find some coordinates of point on the graph of function.

For x = 0,

f(0) =  (30³ + 2)/(0^2-5)

f(0) = 2/(-5)

f(0) = -0.4

For f(x) = 0,

0 = (3x³ + 2)/(x^2-5)

(3x³ + 2) = 0

3x³ = -2

x = -0.874

for x = 1,

f(1) = (3(1)³ + 2)/(1^2-5)

f(1) = 5/(1 - 5)

f(1) = 5/(-4)

f(1) = -1.25

The graph of function f(x) = (3x³ + 2)/(x2-5) is as shown below.

Therefore, the two points that could be used to plot the graph of the function (0, -0.4) and (-0.874, 0)

Answer: The answer is 570.

Step-by-step explanation:

So, if you know what numbers are, when you round, this question is easy. If you take a number line and put 570 on the left side and 580 on the right side, and 575 in the middle, you almost got it. Since the number we want to round is 573, we put it in the middle of 570 and 575. And since the number is closer to 570 than 580, the answer is 570. Your welcome!

The points on the scatter plot show the different predictions. The straight line drawn is called the line of regression.

Errors in prediction for each point can be determined by drawing a vertical line from the point to the line of regression. As seen in the image, all of the prediction points are found on the line except for points (14,25) and (16,25). Therefore, these points contain errors in prediction.

So the new coordinates of point C are (1, 2), and the image of Triangle ABC is congruent to the original triangle.

A triangle is a closed, two-dimensional geometric figure with three straight sides and three angles. It is one of the basic shapes in geometry and can be classified based on the length of its sides or the size of its angles. A triangle with all sides of equal length is called an equilateral triangle, while a triangle with two sides of equal length is called an isosceles triangle. A triangle with no sides of equal length is called a scalene triangle. Triangles can also be classified based on the size of their angles, with an acute triangle having all angles less than 90 degrees, a right triangle having one angle equal to 90 degrees, and an obtuse triangle having one angle greater than 90 degrees.

Here,

To find the new coordinates of point C after the rotation and translation, we need to perform each transformation separately and then combine them.

Rotation:

To rotate a point 180° counterclockwise about the origin, we switch the sign of both coordinates. Therefore, the new coordinates of point C after the rotation are (-3, -2).

Translation:

To translate a point to the right 4 and up 4, we add 4 to the x-coordinate and 4 to the y-coordinate. Therefore, the new coordinates of point C after the translation are (1, 2).

To determine if the image of Triangle ABC is similar or congruent to the original triangle, we need to compare the corresponding sides and angles of both triangles.

Since we performed a rotation of 180°, all the angles in the image triangle are congruent to the corresponding angles in the original triangle. Additionally, since we performed a translation, the sides of the image triangle are congruent to the corresponding sides of the original triangle. Therefore, the image triangle is congruent to the original triangle.

What is simple interest ?

The interest on a loan or principal amount can be easily calculated using simple interest. Simple interest is a notion that is employed across a wide range of industries, including banking, finance, automobiles, and more. When you pay back a loan, the monthly interest is deducted first, and any remaining funds are applied to the principle.

The formula for simple interest helps you find the interest amount if the principal amount, rate of interest and time periods are given.

Simple interest formula is given as:
SI = \(\frac{PRT}{100}\)
Where SI = simple interest
P = principal
R = interest rate (in percentage)
T = time duration (in years)
In order to calculate the total amount, the following formula is used:
Amount (A) = Principal (P) + Interest (I)

Where,
Amount (A) is the total money paid back at the end of the time period for which it was borrowed.

The total amount formula in case of simple interest can also be written as:

A = P(1 + RT)
Here,

A = Total amount after the given time period
P = Principal amount or the initial loan amount
R = Rate of interest (per annum)
T = Time (in years)

Given,
P = 450
R = 3%
T = 4

Formulate and substitute: 450+ 450RT

Calculate the product or quotient: 450 X (1+0.12)

Calculate the sum or difference: 450 X 1.12

Calculate the product or quotient: 504

Peter left Town A around 10 a.m., traveling at an average speed of 84 km/h. William would reach Town B at 1:23 PM.

Firstly, we need to find the distance between Town A and Town B which can be calculated by calculating the distance travelled by Peter

Time taken by Peter = 2PM - 10AM

= 4 hrs

Speed of Peter = 84 km/h

Distance travelled by Peter = speed × time

= 84 × 4

= 336 km

So, the distance between Town A and Town B  = distance travelled by Peter = 336 km.

Now, we will calculate time taken by William.

Speed of William = 70 km / hr

Distance travelled by William = distance between Town A and town B = 336 km

Time taken by William = distance / speed

= 336 / 70 hr

= 4.8 hr

This can b converted into hrs and minutes

4.8 hr = 4 hr + 0.8 × 60

= 4 hr 48 mins

Time William took off = 10 AM - 1hr 25 mins

= 8:35 AM

Now, we will calculate the time William would reach town B.

Time = 8:35 + 4hr 48 mins

= 1:23 PM

Step-by-step explanation:

the line thats in between the two squares is the median. Town A's median is 30 and Town B's median is 40, making Town's A median less than Town B's. hope i helped:)

The median for town A at 30° is less than the median for town B at 40°. So option (D) is the correct answer.

"The median is the "middle" of a sorted list of numbers. To find the median, place the numbers in value order and find the middle number".

For the given diagram,

Town A has temperatures = 20°, 30°, 40°

Town B has temperatures = 30°, 40°, 50°

The median of A = 30°

The median of B = 40°

From the above values, the median for town A at 30° is less than the median for town B at 40°.

The simplified expression of \(5\frac{1}{6} -7\frac{1}{3}\)  is\(-2\frac{1}{6}\) .

A fraction represented with its quotient and remainder is  called a mixed fraction.

To convert a mixed number into an improper fraction, multiply the whole number with the denominator of the proper fraction. Add the numerator of the proper fraction to this product to obtain the numerator of the improper fraction.

According to the given question

We have an expression

\(5\frac{1}{6} -7\frac{1}{3}\)

Before, simplifying the expression convert the given mixed fraction into improper fraction of the given expression.

So, \(5\frac{1}{6} =\frac{31}{6}\)

and, \(7\frac{1}{3} =\frac{22}{3}\)

Substitute these values in the given expression

⇒ \(5\frac{1}{6} -7\frac{1}{3} = \frac{31}{6} -\frac{22}{3}\)

⇒\(5\frac{1}{6} -7\frac{1}{3} = \frac{31-2(22)}{6}\)

⇒\(5\frac{1}{6} -7\frac{1}{3} =\frac{31-44}{6}\)

⇒\(5\frac{1}{6} -7\frac{1}{3} =\frac{-13}{6}\)

⇒\(5\frac{1}{6} -7\frac{1}{3} = -2\frac{1}{6}\)

Hence, the simplified expression of \(5\frac{1}{6} -7\frac{1}{3}\)  is\(-2\frac{1}{6}\) .

The temperature at 8:00 A.M. was 15°C.

Using the given information:
1. At 7:00 P.M., the temperature was 16°C.
2. This temperature was 9°C less than the temperature at 2:00 P.M.

We can use this information to find the temperature at 2:00 P.M.:
Temperature at 2:00 P.M. = 16°C (temperature at 7:00 P.M.) + 9°C
Temperature at 2:00 P.M. = 25°C

3. The temperature at 2:00 P.M. was 10°C higher than the temperature at 8:00 A.M.

Now, we can find the temperature at 8:00 A.M.:
Temperature at 8:00 A.M. = 25°C (temperature at 2:00 P.M.) - 10°C
Temperature at 8:00 A.M. = 15°C

By analyzing the graph and evaluating the objective function at each vertex of the feasible region, we can find the optimal solution, which is the vertex that maximizes the objective function z = 3x + y.

To find the optimal solution of the given problem using the graphical method, we need to plot the feasible region determined by the given constraints and then identify the point within that region that maximizes the objective function.

Let's start by graphing the constraints:

1. Plot the line 2x - y = 5. To do this, find two points on the line by setting x = 0 and solving for y, and setting y = 0 and solving for x. Connect the two points to draw the line.

2. Plot the line -x + 3y = 6 using a similar process.

3. The x-axis and y-axis represent the constraints x ≥ 0 and y ≥ 0, respectively.

Next, identify the feasible region, which is the region where all the constraints are satisfied. This region will be the intersection of the shaded regions determined by each constraint.

Finally, we need to identify the point within the feasible region that maximizes the objective function z = 3x + y. The optimal solution will be the vertex of the feasible region that gives the highest value for the objective function. This can be determined by evaluating the objective function at each vertex and comparing the values.

Note: Without a specific graph or additional information, it is not possible to provide the precise coordinates of the optimal solution in this case.

When random numbers are picked between 1 and 7the median and the mean is located approximately on point B.

The frequency that is acquired this manner is known as the cumulative frequency in statistics. The frequency of the first-class interval is added to the frequency of the second class, and this total is added to the third class and so on (c.f.). A cumulative frequency distribution or cumulative frequency table is a table that shows the cumulative frequencies that are dispersed throughout different groups.

For the given distribution of numbers calculate the cumulative frequency depending on the frequency.

Number Frequency CF

1                    3            3

2                   3            6

3                   3            9

6                   3            18

7                   3            21

The median of the frequency table is:

Median = (n+1)/2 = (21+1)/2 = 11

11th position in the table corresponds to 4, and hence the approximate location of the median is B.

Mean = (3)(1+2+3+4+5+6+7)/ 21 = 4
