Since there are 3 and assuming that they're the same size each radius is 1.5, as is the radius of the base of the cylinder. So you have to figure out the volume of one of the balls and multiply it by three. Formula: (4/3) * pi * radius^3. The volume of all three is 42.42. Then you need to find the volume of the cylinder. formula: pi * h * r^2. So it is 63.62. You now take this measure and subtract the volume of the three balls: 21.2in^3. To find the percentage, take 21.2/63.62. Then multiply by 100. The answer is 33.32, so your final answer is A.

Suppose A is n x n matrix and the equation Ax = 0 has only the trivial solution. Explain why A has n pivot columns and A is row
vovangra [49]

Answer:

Remember, a homogeneous system always is consistent. Then we can reason with the rank of the matrix.

If the system Ax=0 has only the trivial solution that's mean that the echelon form of A hasn't free variables, therefore each column of the matrix has a pivot.

Since each column has a pivot then we can form the reduced echelon form of the A, and leave each pivot as 1 and the others components of the column will be zero. This means that the reduced echelon form of A is the identity matrix and so on A is row equivalent to identity matrix.
