Use the hat-symbol for exponents, for example type A*2 for A2, and use commas to separate the answers. RO b) If defined, what are the dimensions of AB? If AB is undefined, type "undefined" in both boxes. [Number of rows [Number of columns | Number Number c) If defined, what are the dimension of BA? If BA is undefined, type "undefined" in both boxes. [Number of rows [Number of columns Number Number The equations below are derived from a circuit diagram using Kirchoff's and Ohm's laws. Find the current running through each component (i.e. find I, Iy and I3). The units are Amperes. Solve the system of equations. You may use any method. L+, + I3 =0 11 =313 + 2 0.08I, 041y = 4 Round your answers to 3 significant digits. L= (A) I = (A) I3 = (A) Use the system of equations shown below to answer the following question 2z-y=-9 2z-5y=-9 When using Cramer's rule you would need to use the formulas ._De _Dy =D Y= Determine the matrices you would use for calculating Dy and D: Determine the solution for y If there is no solution, write "no solution" Use exact answers only, no decimals y= =
