Answer:
(a)
(b)
(c)
Step-by-step explanation:
(a) This is a sequence of consecutive number
(b) This is a sequence of 2 to the power of n - 1. The next number is twice time of this number
(c) This is factorial sequence. Where the next number is this number multiplied by 
One metre=10 decimetres.
Therefore 30 metres = 30*10=300 decimetres.
Answer: Depends on the orders pairs
Step-by-step explanation: You didn’t include the ordered pairs so I’ll just do an example.
(1,5). (2,11). And(6,13) Theese orders pairs represent a function because, there are no repeating X values.
(2,5) (2,10) and (5,45)
Theese ordered pairs do NOT represent a function because, the X values repeat.
A function can be linear and nonlinear, they can have repeating Y values but NO repeating X values.
A trick for this is to put a piece of paper and cover sections and see if your line “turns back”.
Hope I helped ^u^
Answer:
I solved the question in three methods factorization, completing the square and quadratic equation . the continuation of completing the square is on the next page titled page 3
