Which number is a factor of 162?

A
9

B
5

C
7

D
10

Option A

Step-by-step explanation:

Remember a factor is a number that is divisible by another number or can be multiplied by another integer to equal that same number. In this case we have to find the number of 162 and in order to do that we have to find the number that we can then multiply by another number to equal 162 or just divide 162 by the options into one of them equals a number that isn't a decimal.

Hope this helps.

Option A. = 9

Step-by-step explanation:

Factors of a number are numbers you Multiply to get another number.

For example:

The factors of 6 are 2 * 3

The factors of 18 are 1*18, 2*9, 3*6,

Also,

The factors of a number, are numbers that can divide through another number perfectly without a remainder

With that knowledge:

The factors of 162 are:

1*162, 2*81, 3*54, 9*18 etc

If you observe well, of all the options, only 9 appears.

Hence 9 is the correct answer.

Option A

idk bring the function back   im not smart

step-by-step explanation:

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
