Answer

No

Yes ...?

Answers

Yes, it is definitely a function. Although one might say that it is not a one to one or injective function because of the presence of (-1,-2) and (6,-2).. The correct option among the two options that are given in the question is the second option. I hope that this is the answer that has actually come to your desired help.

A sequence of numbers begins with 12 and progresses geometrically. Each number is the previous number divided by 2.Which value can be used as the common ratio in an explicit formula that represents the sequence?


2
6
12

Answers

The common ratio is the current number divided by the previous. So the ratio is 1/2

The sequence is 12, 6, 3, 3/2, 3/4 ...

You can obtain any number multiplying the previous number times 1/2.

6 = 12 *(1/2)

3 = 6*(1/2)

3/2 = 3*(1/2)

Answer:

Common ratio = (1)/(2)

Step-by-step explanation:

A sequence that progresses geometrically has the first term as 12.

Each number is the previous number divided by 2.

so the sequence will be 12, 6, 3, 1.5...........

Explicit formula of a geometric sequence is given by

T_(n)=a(r)^(n-1)

Where T_(n) = nth term of the sequence

a = first term

r = common ratio

and n = number of term

In this sequence common ratio = \frac{\text{Successive term}}{\text{previous term}}

= (6)/(12)

= (1)/(2)

Therefore, common ratio will be (1)/(2)

rogers father knows that dial it up sells data plans at $16 for 2 gigabytes and ring sells data plans at $9 for 1 gigabytes

Answers

Answer:

Dial it up : ring ring

=8:9

Step-by-step explanation:

From Dial it up= $16 per 2 gb.

ratio of gb : price

2:16

can be reduced to 1:8

this means that per each Gigabyte, you pay $8.

Ring Ring has plans of $9 per 1gb

ratio of gb to price is 1:9

And the ratio between the prices

of the companies is

Dial it up:ring ring

8:9

which means that in one company you get one gb for $8, while in the other company you get the same one gb for $9.
