Compute the error r(xo) (also called the residual) at xo for the matrix a and the inhomogeneous term b given below. use the normal equation to find the least squares solution to ax = b. compute the minimum residual obtained by least squares approximation, and compare its norm to the norm of r(xo). 2 a=[1 3-1 -2 2 2] b= [1 0 0 ] x0 = [1 1]

sss (side, side, side)

sas (side, angle, side)

asa (angle, side, angle)

aas (angle, angle, side)

hl (hypotenuse, leg)

c is the answer

step-by-step explanation:

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
