Which of these is a geometric sequence?
A. 3, 6, 9, 12,...
B. 2, 3, 5, 9, 17
C. 4, 2, 1, 1/2, 1/4
D. 3,-15, -33, -51, -69,

Answers

Answer 1

Answer:

C. 4, 2, 1, 1/2, 1/4

Step-by-step explanation:

Geometric is normally either division or multiplication sequences. C has the division sequence of dividing by 2.

A would be an example of an arithmetic sequence.

Answer 2

The series 3, 6, 9, 12,... and  4, 2, 1, 1/2, 1/4 are geometric series.

Options A and C are the correct answer.

What is a geometric sequence?

A geometric sequence is a sequence of numbers in which the ratio between consecutive terms is constant.

We have,

Looking at the options:

A.

3, 6, 9, 12,... is a geometric sequence with a common ratio of 2.

Each term is found by multiplying the previous term by 2.

B.

2, 3, 5, 9, 17 is not a geometric sequence because there is no constant ratio between terms.

C.

4, 2, 1, 1/2, 1/4 is a geometric sequence with a common ratio of 1/2.

Each term is found by multiplying the previous term by 1/2.

D.

3,-15, -33, -51, -69, is not a geometric sequence because there is no constant ratio between terms.

Therefore,

The series 3, 6, 9, 12,... and  4, 2, 1, 1/2, 1/4 are geometric series.

i need help telling if these are true or false

Answers

Answers:

FalseTrueFalseTrue

======================================================

Explanations:

Point A is located at (0,1). It then moves to A' which is at (0,3). Note the y coordinate goes from y = 1 to y = 3, so the scale factor is 3/1 = 3 instead of 4. Therefore, the claim is false.Point A is at (-4,4). It moves to (-2,2). Each coordinate of (-4,4) is cut in half to get (-2,2). Cutting a value in half is the same as multiplying by 0.5, so point A fits the description. Let's find out if point B does as well. B is at (2,4) and it moves to B' (1,2); we can see that point B has its coordinates cut in half as well. Points C and D also work to fit the description (I'll let you check those coordinates) which means overall, quadrilateral ABCD dilates with a scale factor of 0.5 to get to quadrilateral A'B'C'D'. The answer here is "true".Point W is at the location (-1,1). Triple each coordinate to get (-3,3) which is where point W' should be located if we applied the dilation of scale factor 3. However, the diagram shows W' is not at (-3,3). It seems to be fairly close to (-2,2) if anything. We don't need to check the other points, but I recommend you do so just for practice. The answer here is "false".Because the scale factor is 0.25 = 1/4, this means "scale factor of 0.25" is the same as "scale factor of 1/4". That tells us to "multiply each coordinate by 1/4" which in turn is equivalent to "divide each coordinate by 4". Point E is at (-4,4) which moves to (-1,1) when we divide each coordinate by 4. Note how point E' is at (-1,1). So E moves in the proper way according to the instructions given to us. Points M, W and O also move in a similar fashion after we divide their coordinates by 4. The answer here is "true".

Answer:

Step-by-step explanation:

The perimeter is twice the sum of length and width. You want x such that ...

  P > 156

  2(x +(x+8)) > 156

  4x +16 > 156 . . . . . simplify

If we have a conversion factor given to us in a fraction form that cannot be represented as an easy decimal, what can we do?

a. Conclude that the units cannot be converted to one another.
b. Assume the conversion factor is 1.
c. Attempt to use a conversion factor for different units of measurement.
d. Leave the conversion factor in fraction form.

Answers

Answer:

D) Leave the conversion factor in fraction form

Step-by-step explanation:

Leave the conversion factor in fraction form, when fraction form that cannot be represented as an easy decimal. The correct option is option D.

What is conversion Factor?

A conversion factor is a ratio expressed as a fraction that equals 1. When we use conversion factors to convert units, we multiply our original measurement by the conversion factor to get the same measurements expressed in new units.

If we have a conversion factor given to us in a fraction form that cannot be represented as an easy decimal. Leave the conversion factor in fraction form.

Because there are two type of decimals:

Terminating decimal expansion means the decimal expansion of a number which stops after a certain number of decimal places. For example, if we divide 100 by 16, the answer comes out as 6.25.Since the number of decimal place in 6.25 is 2,i.e., it stops after a certain number of decimal places, it is called a terminating decimal expansion.

On the other hand, if the decimal expansion of a number does not stop at all, then it is called a non-terminating decimal expansion. For example, if we divide 100 by 7, then the answer comes out to be 14.28571428571…….. . The decimal expansion does not stop. This is known as a non-terminating decimal expansion.

In general, if a fraction has a denominator of the form 2^n*5^m, where m and n are non-negative integers, then it will have a terminating decimal expansion. For example, 100/16 has denominator 16 which is of the form 2^4*5^0, so it has a terminating decimal expansion.

If a fraction has a denominator which is not of the form 2^n*5^m, where m and n are non-negative integers, then it will have a non-terminating decimal expansion. For example, 100/7 has a denominator 7 which is not of the form 2^n*5^m so it has a non-terminating decimal expansion.

Hence, Leave the conversion factor in fraction form, when fraction form that cannot be represented as an easy decimal.
