Basically, we are trying to find the third number in the pattern. The pattern is - -4, -2, -12, -14 and so on. We can see that the third number is -12, which is a₃. Therefore, the answer is C) -12. Hope this helped!

Answer:

C.)-12

Step-by-step explanation:

A sequence is an ordered list of numbers.

One way to define the sequence is by listing the numbers of the sequence.

This list is

a1,a2,a3,a4,a5, ... ,an

Where a1 is the first number of the sequence, a2 is the second number of the sequence , ... , an is the ''nth'' number of the sequence meaning that the sequence has a total of ''n'' numbers.

In this exercise, the sequence is

-4,-2,-12,-14,...

This means that the first number of the sequence is -4 ⇒ a1 = -4

The second number is -2 ⇒ a2 = -2

The third number is -12 ⇒ a3 = -12

The value of a3 in the sequence is -12

The correct option is C.)-12

Answer:

x = 10

Step-by-step explanation:

The total measures of a circle must add up to 360°.  In the diagram given there are two angles that are not given, however, both of these should be equal to each other.  That means that the sum of the other two angles ('5x - 5' and 93°) must be equal to the other angle of the same measure (138°):

5x - 5 + 93 = 138

Combine like terms: 5x + 88 = 138

Subtract 88 from both sides: 5x + 88 - 88 = 138 - 88 or 5x = 50

Divide by 5:  5x/5 = 50/5 or x = 10

Answer:

  • See below

Step-by-step explanation:

<u>The roots are:</u>

  • 3, 3, 2 - 3i, 2 + 3i (conjugate of 2 - 3i should be added) and the leading coefficient is - 5

<u>The polynomial is:</u>

  • -5(x - 3)² (x - [2 - 3i]) (x - [2 + 3i]) =
  • - 5(x² - 6x + 9) (x² - 4x + 13) =
  • -5(x⁴ - 10x³ + 46x² - 114x + 117) =
  • -5x⁴ + 50x³ - 230x² + 570x - 585

Which shape has a line of symmetry that can be drawn through the figure?
zimovet [89]

Answer: Option D.

Step-by-step explanation:

A figure has a line of symmetry if we can draw a line through the figure, in such way that the line cuts the figure in exactly two equal halves.

Then any figure that can be cutin exactly two halves, is a correct answer to this question.

Then:

For a circle, the line of symmetry is the diameter of the circle.

For the square, the line of symmetry can be obtained by cutting the square with a line that is perpendicular to one of the sides, and cuts that side exactly on the midpoint.

For an equilateral triangle, the line of symmetry is the line that cuts any base in the midpoint and also passes through the opposite vertex.

Then all the figures are correct options, then the correct option is D
