Found out how to do it. Pretty much fill in the rest of the information with the identity matrix.

Dosen't say anything against it. I know what the answer is becuase he gave it to us. It was like: Dim of Col(A) = 2, dim Row(A) = 2, Dim Nul(A^T) = 1 Basis Row(A) = {[-1 1 0], [-1 - 1]}. Because A is symmetric, Col(A) = Row(A) and Nul(A^T) = Nul(A). I understand everything after the...

A 3x3 symmetric matrix has a null space of dimension one containing the vector (1,1,1). Find the bases and dimensions of the column space, row space, and left null space. I understand how to get the Dim of Col(A), Row(A), and Nul(A^T) but how do i get the bases with just knowing the dimension...

Find the change in volume of 1.00 gallon of water when it's taken from the surface of the ocean (P0 = 1.00 atm) to a depth where the absolute pressure is P=251 atm. Bulk modulus of water = 2.10 x 10^9

Homework Statement A constricted horizontal tube of radius r1 = 4.00cm tapers to a tube of radius r2 = 2.50cm. If water flows at a speed 3.50m/s in the larger tube, (A) find its speed in the smaller tube. (b) Find the water pressure difference ΔP=ΔP1-ΔP2 in kPa and in atm. Homework...
