Consider the complex numbers t = -6 + 41, u = -51, w= 4, and z = 3 - 81. On the complex plane shown, t has been plotted. Question: A. What are the real and imaginary parts of t? Are the real part and the imaginary part real numbers or imaginary numbers? What does i represent? B. What are the real and imaginary parts of u and w? Are u and w real numbers or imaginary numbers? What does this tell you about the relationship between real numbers, imaginary numbers, and complex numbers? C. Plot z on a complex plane.​

55.44 inches

step-by-step explanation:

part a. assuming a perfectly linear relationship, we can find the slope from the first two data points.

slope = m = (change in rainfall)/(change in years)

= (61.80 -62.33)/(2005 -2004) = -0.53/1 = -0.53

then the point-slope form of the equation of the line can be written as

y = m(x -h) +k . . . . . m = -0.53, (h, k) = (0, 62.33)

y = -0.53x +62.33 . . . x = years after 2004

part b. in 2017, x = 2017 -2004 = 13. then the predicted rainfall is

y = -0.53·13 +62.33 = 55.44 . . inches

the predicted rainfall in 2017 is 55.44 in.
