Answer : B and C

Explanation :

firstly, we should know the definition of square matrix. It is a matrix in which number of rows is equal to number of columns

In case of A : it is given that several number of airlines  and several number of columns

if we consider the case of more number of airlines say 5 and we have only 4 cities that these 5 airlines offer services to. Then it will not  form a square matrix

NOTE: it would have formed the square matrix if there would have been equal number of airlines and  cities.

In case of  B: in this case we will have equal number of members in each team.

In case of C : in this case we are given with equal number of  equations and unknowns

In case of D: in this case we have augmented matrix which is formed by appending the column of the matrices given so it can never form a square matrix.

Which of the following equations matches the function shown above?
Ksenya-84 [330]

So, the function is obviously shifted up by 1 so it rules out A and B, and we also see that the period is 4pi rather than 2pi, and using the fact that:

\frac{2\pi}{b}=4\pi \implies \frac{b}{2\pi}=\frac{1}{4\pi}\implies b=\frac{1}{2}

Now that we know our b value, we see that the correct answer would be C.

The length of a rectangle is seven less than twice the length of its width. If the area of the rectangle is 15 square meters, fi
Helga [31]
<h2>Length = 3m</h2><h2>Width = 5m</h2><h3>State where x is accordingly.</h3><h2></h2>

The length of a rectangle is seven less than twice the length of its width.

L = 2W - 7

A = W * L

A = 15

15 = W * L

Substitute the L in terms of W

15 = W * (2W - 7)

15 = 2W^2 - 7W

2W^2 - 7W - 15 = 0

Factorise:

(2W + 3) (W - 5) = 0

Solve for W:

2W + 3 = 0

2W = 0 - 3

2W = 3

W = 3/2

W = 1.5

W - 5 = 0

W = 0 + 5

W = 5

Use the original equation to find L:

L = 2W - 7

L = 2(5) - 7

L = 10 - 7

L = 3

L * W = 15

3 * 5 = 15

If f(x) = x/1 + x, what is the value of f(x+h)
Rasek [7]

Answer:

f(x+h)=\frac{x+h}{1+x+h}

Step-by-step explanation:

Given function is:

f(x) = x/1 + x

In order to find f(x+h) we have to put x+h in place of x

f(x)=\frac{x}{1+x} \\f(x+h)=\frac{x+h}{1+x+h}

Therefore,

f(x+h)=\frac{x+h}{1+x+h}
