Create a matrix with 3 rows and 4 columns. Every element in the first row should be 0, every element in the second row should be 1, and every element in the third row should be 2.

Step-by-step explanation:

The matrix should have

- A row with four horizontal zeros

- A row with 4 horizontal ones

- A row with 4 horizontal twos

Thus, it should have the following form

Always remember that the columns are vertical (just think about normal columns) and the rown are horizontal.

I hope that works for you!

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
