15.71 is approx 5pi
Answer: you don’t have ever been
Step-by-step explanation:
The answer is 3,000 because the 7 is larger than 5, so you round the 2 to a 3.
Answer: (f·f)(0) = 4
(fof)(0) = -8
<u>Step-by-step explanation:</u>
f(x) = 3x - 2
(f·f)(x) = (3x - 2)(3x - 2)
= 9x² - 12x + 4
(f·f)(0) = 9(0)² - 12(0) + 4
= 4
(fof) = 3(3x - 2) - 2
= 9x - 8
(fof)(0) = 9(0) - 8
= -8
<em>I wasn't sure if you wanted multiplication or composition so I solved both</em>
Step-by-step explanation:
<u>Here:</u>
<u>Therefore, the matrix A + 2B will be:</u>
<u>Therefore:</u>
<u>Matrix:</u> A matrix is a rectangular arrangement of numbers in the form of horizontal and vertical lines.
Horizontal lines are called rows and vertical lines are called columns.
<u>Order of Matrix:</u> A matrix containing x rows and y column has order x × y and it has xy elements.
<u>Different types of matrices:</u>
Row Matrix: This type of matrices have only 1 row. <u>Example:</u>
<u>Column Matrix:</u> This type of matrices have only 1 column. Example:
<u>Square Matrix:</u> In this type of matrix, number of rows and columns are equal. Example:
<u>Zero Matrix:</u> It is a matrix with all elements present is zero. Example:
<u>Identity Matrix:</u> In this type of matrix, diagonal element is 1 and remaining elements are zero. An Identity matrix is always a square matrix. Example:
