Answer:
Option 3 and 5 are correct
Step-by-step explanation:
We have given a geometric series 640,160,40,10....
Common ratio of geometric series is
Here our common ratio is less than zero
It will show the graph of exponential decay
Hence, option 5 is correct.
The general term of geometric series is
Domain will be all natural numbers since, geometric series take only natural numbers.
Here, values of "n" is domain
Hence, option 3 is correct.
Range can be any positive real numbers not only natural number
Range is the value of
Hence, option 4 is discarded.
Graph can not be linear of a geometric series being exponential
Hence, option 2 is discarded.
Option 1 is discarded because it is exponential decay function so it can not be exponential growth.
Therefore, Option 3 and 5 are correct.
I hope this helps you understand how to do the problem.
Answer:
= {1,3,5,7,9,....}
= {1,2,4,5,7,8,10,11,13,14......}
= {1,2,3,4,5}
= {10,11,12,13,14,15,......}
Step-by-step explanation:
Solution:
It is given that, Universal set is the set of all Natural Numbers.
and
Set A, Set B, Set C, Set D are subsets of Universal set.
A = {x:x is even natural numbers} = {2,4,6,8,10,.....}
B = {x:x ∈ N and x is a multiple of 3} = {3,6,9,12,15,....}
C = {x:x∈ N and x < 5} = {6,7,8,9,10,.....}
D = {x:x ∈ N and x > 10} = {1,2,3,4,5,6,7,8,9}
U = {1,2,3,4,5,6,7,8,9,10,11,........}
Complements:
= U-A = {1,2,3,4,5,6,7,8,9,10,11,........} - {2,4,6,8,10,.....}
= {1,3,5,7,9,....}
= U-B = {1,2,3,4,5,6,7,8,9,10,11,........} - {3,6,9,12,15,....}
= {1,2,4,5,7,8,10,11,13,14......}
= U-C = {1,2,3,4,5,6,7,8,9,10,11,........} - {6,7,8,9,10,.....}
= {1,2,3,4,5}
= {1,2,3,4,5,6,7,8,9,10,11,........} - {1,2,3,4,5,6,7,8,9}
= {10,11,12,13,14,15,......}
