Y = 16.. If you are solving for Y then the answer is 16. Unless you didn't post the whole question, then I believe that is your answer.
Answer:
[2 5 0]
[-7 -11/2 12]
Step-by-step explanation:
We want to perform elementary row operation represented by R2 - ½R1 on matrix A in the figure attached.
Now, matrix A is given as;
[2 5 0]
[-6 -3 12]
Now, R1 is row 1 = [2 5 0]
R2 is row 2 = [-6 -3 12]
Thus, R2 - ½R1 = [-6 -3 12] - ½[2 5 0]
This gives;
[-6 -3 12] - [1 5/2 0] = [-7 -11/2 12]
Now,[-7 -11/2 12] will be the new row 2 since it's just an elementary row operation we did on the Matrix A.
Thus, the new matrix is now;
[2 5 0]
[-7 -11/2 12]
The slope is 5/1. This is because it goes up 5 units and right one unit. This corresponds with the fact that slope is the rise/run on a line.

Answer:
Step-by-step explanation:
Hey
So we are given circumference as 81.681.64m
Formulae for circumference is 2 pi r
When you substitute 2(3.14)r= 81.64m
R = 13m
Area of the horizontal cross section is just the circle above the cylinder and the formulae is pi r^2
So it will be 3.14(13)^2
To give you 530.66m^2
Hope this helped
