'''1.''' What is the solution to the following linear system of equations?

{$A x = b$}

where ''A'' is a matrix and ''b'' is a vector (both known) with vector ''x'' unknown.

->'''A.''' {`A=bx^T`}

'''2.''' What is a possible function to solve {`x=A^{-1}b`} in Python?

->'''A.''' numpy.array()

-->(:toggle hide q2a button show="Select":)
(:div id=q2a:)
-->%red%Incorrect.%% The ''array'' function builds a Numpy array.
(:divend:)

->'''B.''' numpy.solve()

-->(:toggle hide q2b button show="Select":)
(:div id=q2b:)
-->%red%Incorrect.%% The ''solve'' function is in the linear algebra ''linalg'' package that is contained in numpy.
(:divend:)

->'''C.''' numpy.linalg.solve()

-->(:toggle hide q2c button show="Select":)
(:div id=q2c:)
-->%blue%Correct.%% Another potential strategy to solve the linear equations is with ''numpy.dot(numpy.linalg.inv(A),b)''.
(:divend:)

->'''D.''' None of the above

-->(:toggle hide q2d button show="Select":)
(:div id=q2d:)
-->%red%Incorrect.%%

'''3.''' It is important to distinguish between linear and nonlinear equations to know which solution strategy to use. Select the equation that is nonlinear.

->'''A.''' {`10^2x+(15y+3)=10`}

-->(:toggle hide q3a button show="Select":)
(:div id=q3a:)

(:div id=q3b:)

(:divend:)

->'''C.''' {`5x^2+3y+2=0`}

-->(:toggle hide q3c button show="Select":)
(:div id=q3c:)
