Is the sequence 3, 12, 36, a geometric sequence?

No

Step-by-step explanation:

In a geometric sequence there is a common ratio. The common ratio is the number that when multiplied by a number in the sequence gives you the next number. To find the common ratio, you divide any number by the previous number. Every division must give you the same answer, the common ratio.

Now try to find the common ratio of this sequence.

36/12 = 3

12/3 = 4

The ratios between terms are not equal. There is no common ratio.

Therefore, this sequence is not a geometric sequence.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
