3. Why is a square both a rhombus and a rectangle?

Mathematics
1 answer:
Korolek [52]2 years ago
7 0
A rhombus is a shape that has all four sides equal, whether they be in the shape of a parallelogram, or a square, if it has all four sides equal length, it's a rhombus. The definition of a rectangle, is a shape that has four right angles. (90 degrees).

So, if a square has all four sides equal, and four right angles, it can be both a rhombus and a rectangle.

Not all rhombuses are squares, because not all have four right angles. Not all rectangles are squares, because they do not all have four equal sides. Not all rectangles are rhombuses because they do not have four equal sides.

But all squares are a rhombus and all squares are a rectangle.

What can be concluded about the sequence 19, 15, 11,
Mariulka [41]

Option first and option second are correct because the common difference of the sequence is the same as the slope of the graph.

<h3>What is a sequence?</h3>

It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.

The question is incomplete.

The question is:

What can be concluded about the sequences 19, 15, 11, 7, . . . represented on the graph? Check all that apply.

  • The common difference of the sequence is the same as the slope of the graph.
  • The slope of the graph is –4.
  • The next term in the sequence is represented by point (4, 3).
  • f(x) = –4x + 19 represents the sequence.
  • An infinite number of points can be determined to follow this sequence.

The graph is attached to the picture please refer to the graph.

We have an arithmetic sequence:

19, 15, 11, 7,...

The first term is:

a = 19

Common difference d = 15-19 = -4

The nth term:

a(n) = 19 + (n-1)(-4)

a(n) = 19 -4n + 4

a(n) = -4n + 23

We can write above expression as:

f(x) = -4x + 23

Slope of the equation = -4

The correct options are:

  • The common difference of the sequence is the same as the slope of the graph.
  • The slope of the graph is –4.

Thus, an option first and option second are correct because the common difference of the sequence is the same as the slope of the graph.
