f: M ⇒ N is a function from M to N.

Given,

f: M ⇒ N

We need to describe this mathematical statement in our own words.

A function is defined as a way where there is an input that it takes and produces an output.

The set from where the inputs come is called the Domain.

The set of outputs is called the Range.

We have,

f: M ⇒ N

Here

f is a function that takes input from the set M and its output belongs to set N( Natural number).

Here,

M is called the domain.

N is called the codomain.

Thus f: M ⇒ N is a function from M to N.

Answer:

4/5

Step-by-step explanation:

Find 2 defined points like (-2,0)(3,4) in other to reach the point (3,4) from (-2,0) it moves 5 times front and 4 times up  

Up is Y value

Front is X value

To solve it is adding the value that you get from moving it in this case

5 front X equals to 5

4 up Y equals to 4

Then is 4/5

because the formula is Y/X

Answer:

  √35 +3√7 -6 . . . square units

Step-by-step explanation:

The area can be figured a number of ways. The figure can be divided into parts, and the areas of those parts added.

Or, the area of the enclosing rectangle can be found, and the rectangle at upper right that is not shaded can be subtracted from that. We choose the latter.

The overall width is the sum of the given partial widths:

  width = (√7 -2) + (2) = √7

Then the area of the bounding rectangle is ...

  A = LW = (√5 +3)(√7) = √35 +3√7

The area of the upper right empty-space is ...

  A = LW = (3)(2) = 6

Then The area of the shaded figure is ...

  √35 +3√7 -6

But where is the question???????

Answer: False

If two lines intersect, then they intersect at one point only, so it makes no sense to mention a second point. This is assuming that we're not talking about two lines intersecting infinitely many times (i.e. one line overlapping another perfectly).

Answer:

B. The distribution is not symmetrical.

Step-by-step explanation:

In order for the distribution to be symmetrical, the median line (line in the box) should be in the center. This box plot is more positvely skewed.

Answer:

A rhombus is a geometric figure that lies in a plane. It is defined as a quadrilateral all of whose sides are congruent. It is a special type of parallelogram, and its properties (aside from those properties of parallelograms) include:

Its diagonals divide the figure into 4 congruent triangles.

Its diagonals are perpendicular bisectors of eachother.

If all of a rhombus' angles are right angles, then the rhombus is a square.

Answer:yes it does have perpendicular lines

A sequence is the pattern or rule that guides the creation of a set. The most common sequence are the arithmetic and the geometric sequence.

The complete question illustrates that we build a sequence of number.

Let the n term of the sequence be [tex]T_n[/tex].

2 times 3 less than the previous number means:

[tex]T_n = T_{n-1} - 2 \times 3[/tex]

Where:

[tex]T_n \to[/tex] The current number

[tex]T_{n-1} \to[/tex] The previous number

Assume the first number starts with 0, the next numbers will be:

[tex]T_2 = 0 - 2 \times 3 = -6[/tex]

[tex]T_3 = -6 - 2 \times 3 = -12[/tex]

[tex]T_4 = -12 - 2 \times 3 = -18[/tex]

So, the sequence is:

0, -6, -12, -18.....

Assume the first number starts with 3, the next numbers will be:

[tex]T_2 = 3 - 2 \times 3 = -3[/tex]

[tex]T_3 = -3 - 2 \times 3 = -9[/tex]

[tex]T_4 = -9 - 2 \times 3 = -15[/tex]

So, the sequence is:

3, -3, -9, -15.....

Answer:

  1. (f+g)(x) = 2x^2 +4x +2

  2. (f -g)(x) = -2x^2 +4x -4

  5. (f+g)(x) = x^2 +2x -1

  6. (g -f)(x) = x^2 -2x -1

Step-by-step explanation:

None of these are compositions. They are only sums or differences.

  (f±g)(x) = f(x) ± g(x)

__

1. (f+g)(x) = f(x) +g(x) = (4x -1) +(2x^2 +3)

  (f+g)(x) = 2x^2 +4x +2

__

2. (f -g)(x) = f(x) -g(x) = (4x -1) -(2x^2 +3)

  (f -g)(x) = -2x^2 +4x -4

__

5. (f +g)(x) = f(x) +g(x) = (2x) +(x^2 -1)

  (f+g)(x) = x^2 +2x -1

__

6. (g -f)(x) = g(x) -f(x) = (x^2 -1) -(2x)

  (g -f)(x) = x^2 -2x -1
