The long range navigation system calculates the position of an incoming object at sea using signals from fixed transmitter. This leads to a cubic interpolating equation ao +a7x+a 2r +a zx³=Cos Write down a system of 4 equations in 4 unknowns ao, a1, az and a 3. at points x, = 0, x1 = 2, x2 = 3 and x3 = 4. and the solve the linear system using Do-little LU factorization method? Select one: a. ao = 1, a1 = -3.3333, az = 1.5, a3 = -0.166667 !! O b. ao = 1, a1 = 3.3333, az = 0.5, az = 0.166667 %3D O c. ao = 1, a1 = 0.3333, a2 = 1.5, a3 = -1.166667 O d. ao = 1, a1 = 2.3333, az = 2.5, az = -1.166667 %3D

Equations and inequalities describe the relationship between two mathematical expressions.

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
