Method 1:
The recursive formula states that every next term is three times the previous one, plus two.
So, we have:
Method 2:
You can write the expression for , and use the recursive formula until you get to the starting point:
Now use the fact that to get the conclusion
Answer:
4 m/s downwards
Step-by-step explanation:
Velocity is given by dividing the distance by time taken to cover the diatance. Therefore, expressed as v=d/t
The distance is given as 24 m but the time given covers only half the distance. Therefore, the distance is 0.5*21=12 m
Time taken is given as 3 s
Substituting 12 m for d and 3 s for t then
V=12/3= 4 m/s
Velocity must have direction component hence velocity is 4 m/s downwards
Possible values of x and y for two distinct points (5, -2) and (x ,y) to represent a function is x ∈ R , x≠ 5 and y ∈ R.
As given,
Two distinct points to represent function are (5, -2) and (x. y )
Possible value of x and y to represent a function.
x represent domain
y represent range.
Each value of x (domain) mapped to y-value(range).
x can not be equal to 5 .
x and y take all real values except x≠5.
Therefore, possible values of x and y for two distinct points (5, -2) and (x ,y) to represent a function is x ∈ R , x≠ 5 and y ∈ R.
