Answer:

Arithmetic: (4, 8, 12, 16, ...) (3, 8, 13, 18, ...)

Geometric: (2, 6, 18, 54, ...) (5, 10, 20, 40, ...)

Neither arithmetic or geometric: (5, 10, 20, 30, ...)

Step-by-step explanation:

Arithmetic sequences are sequences where all of the numbers have a common difference.

4, 8, 12, 16, ... all have a common difference of 4.

3, 8, 13, 18, ... all have a common difference of 5.

Geometric sequences are sequences where all of the numbers have a common ratio.

2, 6, 18, 54, ... all have a common ratio of 3.

5, 10, 20, 40, ... all have a common ratio of 2.

Sequences that are neither arithmetic or geometric do not have common differences or common ratios.

5, 10, 20, 30, ... does not have a common difference or a common ratio

Answer:

correct answer is. Arithmetic: first and third, Geometric: second and fourth, Neither Arithmetic nor Geometric: fifth

Step-by-step explanation:

Formula for Arithmetic sequences is:

aₙ = a₁ + (n - 1) d

First: 4, 8, 12, 16, .... a₁ = 4 and d = 4

Third: 3, 8, 13, 18, ... a₁ = 3 and d = 5

Formula for Geometric sequences is:

aₙ = a₁ · q ⁽ⁿ⁻¹⁾

Second: 2, 6, 18, 54, .... a₁ = 2 and q = 3

Fourth: 5, 10, 20, 40, ... a₁ = 5 and q = 2

Fifth is neither Arithmetic nor Geometric

After triangle ACE is dilated by a factor of 6, it has an area of 180 square inches. What was its area before dilation?
Agata [3.3K]

Answer:

The area of triangle ACE before dilation is:  30 square inches

Step-by-step explanation:

We know that when an object is dilated by a scale factor, it gets reduced, stretched, or remains the same, depending upon the value of the scale factor.

  • If the scale factor > 1, the image is enlarged
  • If the scale factor is between 0 and 1, it gets shrunk
  • If the scale factor = 1, the object and the image are congruent

The length of the image can be determined by multiplying the length of the original point by a certain scale factor.

Given that after triangle ACE is dilated by a factor of 6, it has an area of 180 square inches.

Thus, it means the dilated area is 6 times the area before dilation.

Let x be the pre-dilation area

As the dilated area is 6 times the area before dilation, so

6x = 180

divide both sides by 6

6x/6 = 180/6

x = 30 square inches.

Therefore, the area of triangle ACE before dilation is:  30 square inches
