Question

State which of the following sets are finite or infinite.
(i) {x:x belongs to N and (x - 1) (x - 2) =0}
(ii) {x:x belongs to N x²=4}
(iii) {x:x belongs to N and 2x -2=0}
(iv) {x:x belongs to N and x is prime}
(v) {x:x belongs to N and x is odd}​

Answer 1

Step-by-step explanation:

Here we see the first three figures in the sequence are drawn upside to continue the sequence.

Therefore, the figure that will continue the sequence is F1 Pankaj 22.1.21 Pallavi D5

Hence, the correct answer is A.

Answer 2

Answer:

$\huge\mathfrak\red{question:)}$

State which of the following sets are finite or infinite.

(i) {x:x belongs to N and (x - 1) (x - 2) =0}

(ii) {x:x belongs to N x²=4}

(iii) {x:x belongs to N and 2x -2=0}

(iv) {x:x belongs to N and x is prime}

(v) {x:x belongs to N and x is odd}

$\huge\mathfrak\red{answer:)}$

Here x belongs to integers which can take negative and positive values.

The condition states that x should be less than 5, and so it can take infinite number of negative values.

thus, the set is infinite.
