Both a and b are functions. for it to be a function, you can only have 1 y value per x value.
this is not a function because 1 has 2 y values
(1,3)(2,5)(1,4)(3,2)
Answer:
5.78
Step-by-step explanation:
Multiply 13 to both sides to get q by itself
4/9*13=q
this gives you
5.77777778=q
but we need to round it to the nearest hundredth
so
5.78

Step-by-step explanation:

- Find square root of 144 by factorisation method.

We can find the square root of 144 using the factorisation method. In this method, you need to factorise 144 first. Then, you'll get your answer in the form of prime factors. In this case, it's ⇨ 2 × 2 × 2 × 2 × 3 × 3.
__________________
To find the square root using factorisation, we need to group the same number in pairs. That is, 2 × 2 × 2 × 2 × 3 × 3 by grouping same numbers in pairs will become ⇨ (2, 2), (2, 2), (3, 3).
__________________
Now, you should take only 1 of the number from these groups. So, (2, 2), (2, 2), (3, 3) will change to ⇨ 2 × 2 × 3.
__________________
Finally, just multiply this set of numbers to find the square root of 144. 2 × 2 × 3 = 4 × 3 =
⇨ square root of 144.
