An example of a pure exact number is "3".

In mathematics, pure exact numbers are also known as mathematical constants or closed-form numbers. Unlike approximations, such as those obtained through measurement or estimation, exact numbers have a fixed and well-defined value.

A pure exact number is a number that has a fixed, precise value and is not subject to any estimation or measurement error.

Examples of pure exact numbers include integers (e.g. 3, 42), rational numbers (e.g. 1/2, -3/7), and some real numbers that can be expressed as a ratio of integers (e.g. pi, e).

These numbers have a definite value and do not change, regardless of the measurement or calculation method used.

The objective is to isolate r and make r the subject of the equation:

Cross-multiplication is applied:

The complement of 0.87 is calculated by subtracting the given number from 1. Mathematically, this can be expressed as 1 - 0.87 = 0.13.

The complement of any number x is calculated by subtracting x from 1. This means that the complement of 0.87 is 0.13.

The complement of a number is used to find the remaining portion of a whole. For example, if the given number is 0.87, then the complement of 0.87 is 0.13. This means that 0.87 is 87% of the whole and 0.13 is the remaining 13%. Thus, the complement of 0.87 is 0.13.

Complements can also be used to find the probability of something happening. For example, if the probability of an event occurring is 0.87, then the probability of it not occurring is 0.13. This is because the sum of the probabilities must equal 1 (100%). Therefore, the complement of 0.87 is 0.13.

Answer: The rate of revolutions per minute is 308.8 revolutions per minute.

Step-by-step explanation: To find the rate of revolutions per minute, we need to convert the number of degrees of rotation per second to the equivalent number of full rotations per minute.

First, divide the number of degrees of rotation per second by 360, which is the number of degrees in one full rotation:

1848 / 360 = 5.13

Next, multiply the number of full rotations by 60 to get the number of rotations per minute:

5.13 * 60 = 308.8

So, the rate of revolutions per minute is 308.8 revolutions per minute.

The data analyst should a)investigate the outlier to determine if it can lead to any important observations and b)use a filter to highlight the outlier, as it is more important than the rest of the data.

When analyzing data, it is important to look at outliers as they can provide valuable information. Outliers can point to an unexpected correlation or reveal a hidden trend that could be missed if they were removed. By investigating the outlier, a data analyst can look for any important observations the outlier might reveal.

Additionally, using a filter to highlight the outlier allows the analyst to focus on the outlier and compare it to the other data points. This can help the analyst to understand how the outlier differs from the rest of the data and draw any relevant conclusions.

Removing the outlier should be avoided as it can lead to data bias and remove important information from the analysis.

Answer:

Table C

Step-by-step explanation:

This is a problem that is just process of elimination. The first step here is to organize all the x values (in each table) by value (lowest to highest). Luckily this has already been done for us. The next step is to establish slope. We can do this from any two points in the table. You find the difference between the y-values (y2-y1), then the x values (x2-x1) (where the points are (x1,y1) (x2,y2)). Now we just need to make sure the rest of the points obey that same slope.

For Example, take table A. The first two points are (1,-1) and (3,1) so using what was said before, the change in the x values is +2, and the change in the y values is +2 as well. Now applying that to the last two points, (5,3) and (8,5) we can see the slope is not the same. The change is x is +3 and the change in y is +2. Therefore we know that Table A does not represent a linear function.

The only table that has a constant slope is Table C with a change in x of +3, and a change in y of +2.

The equation of line a is given as follows:

y = 3x - 2.

The slope-intercept definition of a linear function is given as follows:

y = mx + b.

In which:

The parallel line is defined as follows:

3x - y + 1 = 0.

In slope-intercept format, it is given as follows:

y = 3x + 1.

Hence the slope of line a is given as follows:

m = 3.

(as parallel lines have the same slope).

The intercept is the same as the line 11x + 3y + 6 = 0, hence:

3y + 6 = 0

3y = -6

y = -2

b = -2.

Hence the line a is defined as follows:

y = 3x - 2.

Answer:

The rate of interest per annum is 3%.

Step-by-step explanation:

The rate of interest per annum is 3%.

This can be calculated using the formula:

Simple Interest = (Principal x Rate x Time) / 100

In this case, we know that the Simple Interest = $54 and the Principal = $800, Time = 3 years.

So, we can rearrange the formula to solve for the Rate:

Rate = (Simple Interest x 100) / (Principal x Time)

Plugging in the given values, we get:

Rate = (54 x 100) / (800 x 3)

The resulting equation is 14√3x - 47 = 0.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

The equation is given in the question, as follows:

√(3x+4) = 1+√(3x-11)

Answer:

A) (3x + y)^4:

The Binomial Theorem states that for any real numbers a and b, and any positive integer n, the expansion of (a + b)^n is given by the sum of n terms of the form:

C(n,k)a^(n-k)b^k

where C(n,k) is the binomial coefficient (n choose k).

So, expanding (3x + y)^4:

(3x + y)^4 = C(4,0)(3x)^4(y)^0 + C(4,1)(3x)^3(y)^1 + C(4,2)(3x)^2(y)^2 + C(4,3)(3x)^1(y)^3 + C(4,4)(3x)^0(y)^4

Using the binomial coefficients:

C(4,0) = 1, C(4,1) = 4, C(4,2) = 6, C(4,3) = 4, C(4,4) = 1

Expanding the terms:

(3x + y)^4 = 1(3x)^4(y)^0 + 4(3x)^3(y) + 6(3x)^2(y)^2 + 4(3x)(y)^3 + 1(y)^4

= 1(81x^4) + 4(27x^3y) + 6(9x^2y^2) + 4(3xy^3) + 1(y^4)

= 81x^4 + 108x^3y + 54x^2y^2 + 12xy^3 + y^4

B)

The Binomial Theorem states that for any real numbers a and b and any positive integer n, the expansion of (a + b)^n is given by:

(a + b)^n = C(n, 0)a^n * b^0 + C(n, 1)a^(n-1) * b^1 + C(n, 2)a^(n-2) * b^2 + ... + C(n, n-1)a^1 * b^(n-1) + C(n, n)a^0 * b^n

where C(n, k) represents the binomial coefficient, which can be calculated as n! / (k! (n - k)!).

Applying this to (x - 2y)^6, we get:

(x - 2y)^6 = C(6, 0)x^6 * (-2y)^0 + C(6, 1)x^5 * (-2y)^1 + C(6, 2)x^4 * (-2y)^2 + ... + C(6, 5)x^1 * (-2y)^5 + C(6, 6)x^0 * (-2y)^6

Expanding each term:

C(6, 0) = 6! / (0! 6!) = 1

C(6, 1) = 6! / (1! 5!) = 6

C(6, 2) = 6! / (2! 4!) = 15

C(6, 3) = 6! / (3! 3!) = 20

C(6, 4) = 6! / (4! 2!) = 15

C(6, 5) = 6! / (5! 1!) = 6

C(6, 6) = 6! / (6! 0!) = 1

Now we can substitute each value into the equation:

(x - 2y)^6 = 1x^6 - 12x^5 * 2y + 90x^4 * (-2y)^2 - 360x^3 * (-2y)^3 + 720x^2 * (-2y)^4 - 720x * (-2y)^5 + 1 * (-2y)^6

Answer:

(x - 2y)^6 = x^6 - 12x^5 * 2y + 90x^4 * (-2y)^2 - 360x^3 * (-2y)^3 + 720x^2 * (-2y)^4 - 720x * (-2y)^5 + (-2y)^6.

The expression for the car's position in terms of t would be xcar = t × vcar + x0, where vcar is the car's velocity and x0 is the car's initial position. For the vehicles to eventually meet, these two equations must be equal, so vtruck = vcar + (x_0/t).

From given data, equation of line will be x - 2y = -16.

To find points on the line y = mx + b, choose x and solve the equation for y, or. choose y and solve for x.

The two-point form of a line is used for finding the equation of a line given two points (x1,y1) ( x 1 , y 1 ) and (x2,y2) ( x 2 , y 2 ) on it. The two point-form of a line is:y−y1=y2−y1x2−x1(x−x1) y − y 1 = y 2 − y 1 x 2 − x 1 ( x − x 1 ) OR y−y2=y2−y1x2−x1(x−x2) y − y 2 = y 2 − y 1 x 2 − x 1 ( x − x 2 ) .

It's called this because it clearly identifies the slope and the y-intercept in the equation. The slope is the number written before the x. The y-intercept is the constant written at the end. Let's look at an example: y = 3x + 2.

Answer:

The marked price of the torchlight is Rs. 1960.

Step-by-step explanation:

The marked price (MP) of a torchlight is 40% more than the cost price (CP), so we can calculate the MP using the formula:

MP = CP + (CP x 40%)

The cost price of the torchlight is Rs. 1400, so the marked price is:

MP = 1400 + (1400 x 40%) = 1400 + 560 = 1960

The shopkeeper is selling the torchlight at a 20% discount, so we can calculate the selling price (SP) using the formula:

SP = MP - (MP x 20%)

The marked price of the torchlight is Rs. 1960, so the selling price is:

SP = 1960 - (1960 x 20%) = 1960 - 392 = 1568

So the marked price of the torchlight is Rs. 1960.
