Write a compound inequality that represents the situation. All real numbers are at least -6 and at most 3

  {x ∈ ℝ | -6 ≤ x ≤ 3}

Step-by-step explanation:

For a real number x, numbers that are at least -6 are ...

  x ≥ -6

and numbers that are at most 3 are ...

  x ≤ 3

This can be written as a compound inequality with x in the middle as ...

  -6 ≤ x ≤ 3 . . . . x is a real number

center= (-2,0)

radius= sqrt2/2

step-by-step explanation:

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
