The geometric sequence is found in the relationship between consecutive terms that is constant.
In this problem, as I understand it, none of the functions forms a geometric sequence.
The functions that form a geometric sequence have the form
f (x) = h (a) ^ n where "a" is the constant relation between the successive terms.
If you wrote the function "f (x) = - 2 (3/4) x", you wanted to write instead:
f (x) = - 2 (3/4) ^ x
So that would be the function that forms a geometric sequence, where the relation between the consecutive terms is 3/4.
You can test it by dividing f (x) / f (x-1)
Then you will see that the result of that division will be 3/4.
Answer:
i think i know
Step-by-step explanation:
Answer:
1) 144
2) 1
Step-by-step explanation:
Set up a proportion, then solve.
5/3 = 315/x
Cross multiply
5*x = 5x
3*315 = 945
5x = 945
5x/5 = 945/5
x= 945/5
x= 189
Final answer: The riders are 189
