A set of composite numbers less than 12 .express it in listing and set builder methods

marusya05 [52]

Given:

A set of composite numbers less than 12.

To find:

The set by listing and set builder methods.

Solution:

Composite number: A positive integer is called a composite number if it has at least one divisor other than 1 and itself.

Composite numbers less than 12 are 4, 6, 8, 9, 10.

By using the listing method , the given set can be expression as:

Set = {4, 6, 8, 9, 10}

The numbers 4, 6, 8, 9, 10 are greater than 1, less than 12 and non prime numbers.

By using set builder method, the given set can be expression as:

Set = $\{x|x\neq P,1$

Therefore, the list and set builder notation of the given set are {4, 6, 8, 9, 10} and $\{x|x\neq P,1$ respectively.

(3+i)^2 = c+di, find the value of d.

inna [77]

Answer:

d. $\displaystyle 6$

Step-by-step explanation:

$\displaystyle [3 + i]^2 = [3 + i][3 + i] = 9 + 6i + i^2 → 9 + 6i - 1 → 6i + 8$

Therefore, the d-value is 6.

Find the solution of this system of equations. Separate the x- and y-values with a comma. x - 2y = -23 and x - y = 7

snow_lady [41]

Solve the following system using elimination:
{x - 2 y = -23 | (equation 1)
{x - y = 7 | (equation 2)

Subtract equation 1 from equation 2:
{x - 2 y = -23 | (equation 1)
{0 x+y = 30 | (equation 2)

Add 2 × (equation 2) to equation 1:
{x+0 y = 37 | (equation 1)
{0 x+y = 30 | (equation 2)
Collect results:
Answer: {x = 37 , y = 30
