D=xlx is a whole number)

Mathematics
1 answer:
prohojiy [21]3 years ago
8 0

Answer:

Option (4)

Step-by-step explanation:

D = {x| x is a whole number}

D = {1, 2, 3, 4..........}

E = {x | x is a perfect square between 1 and 9}

E = {4}

F = {x | x is an even number greater than 2 and less than 9}

F = {2, 4, 6, 8}

(E ∩ F) = Set of common numbers of E and F

           = {4}

D ∩ (E ∩ F} = Set of common numbers in the sets of D and (E ∩ F)

                   = {4}

Therefore, Option (4) will be the answer.

In the geometric progression 1, 2, 4… what term is 512?
Levart [38]

The next term is double the previous term, so that the n-th term is given recursively by

\begin{cases}a_1=1\\a_n=2a_{n-1}&\text{for }n>1\end{cases}

This rule tells us that

a_2=2a_1

a_3=2a_2=2^2a_1

a_4=2a_3=2^3a_1

and so on, with the explicit rule

a_n=2^{n-1}a_1=2^{n-1}

for n\ge1.

If 512 is the k-th term in the sequence, then

512=2^{k-1}\implies\log_2512=\log_22^9=\log_22^{k-1}\implies9=k-1\implies k=10
