All the natural numbers which are not prime numbers are composite numbers as they can be divided by more than two numbers (1 and itself).
Example: factors of 12
12 ÷1 = 12
12÷ 2 = 6
12÷3= 4
12÷4 = 3
12÷6=2
12÷12 = 1
= {12,6,4,3,2,1}
Composite Number/ Its Factors
4 = {1,2,4}
6 = {1,2,3,6}
8 = {1,2,4,8}
9 = {1,3,9}
10 = {1,2,5,10}
12 = {1,2,3,4,6,12}
14 = {1,2,7,14}
15 = {1,3,5,15}
16 = {1,2,4,8,16}
18 = {1,2,3,6,9,18}
20 = {1,2,4,5,10,20}
21 = {1,3,7,21}
22 = {1,2,11,22}
24 = {1,2,3,4,6,8,12,24}
25 = {1,5, 25}
Hope it helps!

Answer:
Step-by-step explanation:
A relation from a set X to a set Y is called a function if each element of X is related to exactly one element in Y. That is, given an element x in X, there is only one element in Y that x is related to. ... This is a function since each element from X is related to only one element in Y.
Answer:
y = -5/3 x + 40
Step-by-step explanation:
The general form is y = ax + b, where a is the slope and b is the y intercept.
So immediately you can see that b must be 40, since the line crosses the y axis at 40.
The slope can be calculated by finding two "nice" points on the line that are also grid lines.
How about (0,40) and (6, 30).
Then, calculate the slope by dividing the y difference by the x difference:
(30-40)/(6-0) = -10/6 = -5/3
So C must be the answer.
#4) From the reference angle of 58° we can see that we have the side opposite to that angle as well as the hypotenuse. Recall that sin=opp/hyp so we are going to use sine to find that side
sin(58°) =
(multiply both sides by 19 to isolate x)
19 sin(58°) = x (plug into calculator)
16.1 = x
#5) From the reference angle of 56°, we see that we have the adjacent and the opposite sides. Remember that tan=opp/adj so we will use tangent to find x
tan(56°) =
(multiply both sides by
)
(flip them so x is on the top)
[tex] \frac{12}{tan(56)} = x
8.1 = x
