Need help with Part D and E 

I Review | Constants A voltage divider like that in the figure is to be designed so that vo = kvs at no load (RL = 0) and vo = QVs at full load (RL = R.). Note that by definition a<k<1. (Figure 1) Part A Find R1 Express your answer in terms of the variables k, a, and R.. k-a Ro R = ak Submit Previous Answers Correct Part B Find R2. Express your answer in terms of the variables k, a, and R.. k-a R2 = R. a-ak Submit Previous Answers Correct Part C Specify the numerical values of R1 and R2 if k = 0.75, a = 0.70, and R. = 27 k . Enter your answers numerically separated by a comma. R1, R2 = 2.57,7.71 kN Figure < 1 of 1 Submit Previous Answers Correct Term 1: Correct answer is shown. Your answer 2.571 kN was either rounded differently or used a different number of significant figures than required for this part. Term 2: Correct answer is shown. Your answer 7.714 kN was either rounded differently or used a different number of significant figures than required for this part. Important: If you use this answer in later parts, use the full unrounded value in your calculations. R2 RL Part D If vs = 50 V , specify the maximum power that will be dissipated in R1 and R2. Enter your answers numerically separated by a comma.
