The true statement for the relation is, the order of rows is unimportant.

What is row and column?

A row is an arrangement of items that are put next to or horizontally. A vertical split of items based on category is known as a column. The arrangement is in a left to right direction. The set-up is vertical, from top to bottom.

A table's rows are individual groups of connected data. Rows and columns are found in tables in relational databases (also known as records and fields, respectively).

Consider the given statements,

Entities in a column vary as to kind.

The order of the columns is important.

The order of the rows is unimportant.

The relation R is reflexive but not symmetric since every element is related to itself, but not necessarily to other elements.

(a) The relation R is reflexive.

To determine if the relation R is reflexive, we need to check if every element x in the set A is related to itself. In this case, for any real number x, we have xRx, since 1 ≤ x + x. Therefore, the relation R is reflexive.

(b) The relation R is not symmetric.

To determine if the relation R is symmetric, we need to check if whenever x is related to y, y is also related to x. In this case, if xRy, it means that 1 ≤ x + y. However, for the relation to be symmetric, we would need yRx to hold as well. But if we choose x = 2 and y = -4, we have 1 ≤ 2 + (-4), which is true, but 1 ≤ -4 + 2 is not true. Therefore, the relation R is not symmetric.

The inverse Laplace transform of 6s − 12 /(s²+s)(s²+1) is 2e^(−t) − 2 + 4 sin(t).

We have:

ℒ−1 {6s − 12 /(s²+s)(s²+1)}

= ℒ−1 {A / (s²+s) + B / (s²+1)}

Where A = 2 and B = 4.

Using partial fractions, we can write:

A / (s²+s) + B / (s²+1) = (2s - 2) / (s²+s) + (4 / (s²+1))

Taking the inverse Laplace transform of each term, we get:

ℒ−1 {2s - 2 / (s²+s)} + ℒ−1 {4 / (s²+1)}

Using table 7.1 in the textbook, we know that:

ℒ−1 {1 / s(s+a)} = 1/a [1 − e^(−at)] for a > 0

Therefore,

ℒ−1 {2s - 2 / (s²+s)} = 2ℒ−1 {1 / (s+1)} − 2ℒ−1 {1 / s}

= 2e^(−t) − 2

Using table 7.1 again, we know that:

ℒ−1 {1 / (s²+a²)} = sin(at) / a for a > 0

Therefore,

ℒ−1 {4 / (s²+1)} = 4ℒ−1 {1 / (s²+1)}

= 4 sin(t)

Putting it all together, we get:

ℒ−1 {6s − 12 /(s²+s)(s²+1)} = 2e^(−t) − 2 + 4 sin(t)

Thus, the inverse Laplace transform of 6s − 12 /(s²+s)(s²+1) is 2e^(−t) − 2 + 4 sin(t).

Step-by-step explanation:

supplementary means that two or more angles add together to equal 180 degrees

a straight line equals 180 degrees so the intersecting of a line creates two angles that are supplementary. That means <5 is supplementary with 6 and 7.

<5=<1 because the lines intersecting it are parrell. Using the same thinking process for angle 1 as above, it is supplementary with 2 and 3. and since 1 is equal to 5 it is also supplementary to 2 and 3.

The given polynomials are discussed and grouped into each given category as given below.

What is a polynomial?

A polynomial is a mathematical statement made up of coefficients and indeterminates that uses only the operations addition, subtraction, multiplication, and powers of positive integers of the variables.

We can now look into each polynomial.

a) x³ + 125

   125 is a cube of 5 and also  x³  is the power of x.

So this is a perfect cube.

b) 8p³ - 27

    8p³ is a perfect cube of 2p and 27 is a perfect cube of 3.

So it is a perfect cube.

c) 12x³-9

    This is neither a cube nor a square.

d) a²-100

   100 is a perfect square and so is a².

So this is a difference of perfect squares.

e) 4m² + 25

4m² is a square of 2m and 25 is a square of 5.

But the operator is +

So this is neither a cube nor a difference of a perfect square.

f) 16x²-9

16x² is a square of 4x and 9 is a square of 3.

Also, the operator is -

So this is a difference of perfect squares.

Therefore the above polynomials are discussed and grouped into each given category accordingly.

Frequency tables are used to show the number of occurrence of each data in a dataset.

The complete frequency table is as follows:

\(\begin{array}{cc}{Trick}&{Years}\\52&0&53&1&54&2&55&1&56&2\end{array}\right]\)

The given data are:

54, 56, 53, 54, 56, 55

To complete the frequency table, we simply count each data element and the number of occurrence (i.e. the frequency).

So, we have:

52 has a frequency of 0

53 has a frequency of 1

54 has a frequency of 2

55 has a frequency of 1

56 has a frequency of 2

Answer:

x = 15/2

Step-by-step explanation:

The equation of the plane tangent to the graph of f(x,y) at (1,0) is z = f(1,0) + 2(x - 1) + y.

a.) To find the equation of the plane tangent to the graph of f(x,y) at (1,0), we first need to find the partial derivatives of f(x,y) with respect to x and y. The partial derivative of f(x,y) with respect to x is 2xe^xy, and the partial derivative of f(x,y) with respect to y is x^3e^xy. Evaluating these at (1,0), we get 2(1)(1) = 2 and (1)^3(1) = 1. So the equation of the plane tangent to the graph of f(x,y) at (1,0) is z = f(1,0) + 2(x - 1) + y.

b.) The linear approximation of f(x,y) for (x,y) near (1,0) can be found using the formula L(x,y) = f(1,0) + fx(1,0)(x - 1) + fy(1,0)y, where fx and fy are the partial derivatives of f with respect to x and y evaluated at (1,0). We already found fx(1,0) to be 2 and fy(1,0) to be 1. Evaluating f(1,0), we get f(1,0) = 1, so the linear approximation of f(x,y) near (1,0) is L(x,y) = 1 + 2(x - 1) + y.

c.) The differential of f at point (1,0) is the linear transformation given by df(1,0)(x,y) = fx(1,0)x + fy(1,0)y. Plugging in fx(1,0) = 2 and fy(1,0) = 1, we get df(1,0)(x,y) = 2x + y.

Answer:

874.6

Step-by-step explanation:

total sales = 1045

1045 * .12 = 125.4

fuel = 9 * 5 = 45

1045 - 125.4 - 45 = 874.6

The forecast for May using a five-month moving average is 39 (Option E).

Moving average is used for smoothing out time series data to find any trends or cycles within the data. A five-month moving average is the average of the past five months. To calculate the moving average, add up the sales for the previous five months and divide it by five.

According to the question, the sales for the previous five months are: Nov. 39 Dec. 27 Jan. 40 Feb. 42 Mar. 41 April 47

We have to add the sales of these five months, which gives:

27 + 40 + 42 + 41 + 47 = 197

To find the moving average for May, we divide this sum by 5:

197 / 5 = 39.4

Since we have to round the answer to the nearest whole number, we round 39.4 to 39, which is option E.
