9.Set R= {a, b, c}. Find the number of subsets in set R.(4 Points)​

Mathematics
1 answer:
fredd [130]3 years ago
7 0

Given:

The set is:

R=\{a,b,c\}

To find:

The number of subsets in set R.

Solution:

Formula for number of subsets in a set of n elements is

Number of subsets = 2^n             ...(i)

We have,

R=\{a,b,c\}

Here, the number of elements are 3. Putting n=3 in (i), we get

Number of subsets = 2^3

                                = 8

Therefore, the number of subsets is 8 and the subsets are \phi,\{a\},\{b\},\{c\},\{a,b\},\{a,c\},\{b,c\} and \{a, b, c\}.

Which of the following is the conjugate of 10 − 3i?
Oksana_A [137]
A complex number is made of two parts: one real part (without i) and one imaginary part (with i).
The conjugate of a complex number is found by inverting the sign of the imaginary part of the number.
Therefore, the conjugate of 10+3i is 10−3i
