- 4. Perform the following operations involving complex numbers: а. (2 + 7i) + (3 — 41) ь. (9 + 5і) — (4 + 7) c. (3+2i) (5 + 6i) 3+ 2i d. 4- 5i e. 15 + 2i|arrow_forwardQ21arrow_forwardFind a motion that moves the line x + 2y = 3 to the y-axis and point (1,1) to the origin. Give the answer in the complex form.arrow_forward
- Directions: Set your calculators on radians at this point. Do not round off during intermediate solutions. Use 3 decimal places (if applicable) in your final answer. For complex numbers, use this format (a+jb): 1. No spaces in between! 2. Use 'j' as the imaginary number 3. Use 3 decimal places (if applicable) for Real and Imaginary parts. Ex. 1.247+j0.557, 1.5-j0.5 Calculate the 3-point DFT of the given sequence: x(n) = [10 -1]arrow_forwardSimplify. (2 (cos+ i sin ))³ Enter the answer in the standard form of a complex number with the real part in the first answer box and the imaginary part in the second answer box. If the complex number has no real term, enter "0" in the first answer box. If the complex number has no imaginary term, enter "0" in the second answer box. Express your answer to two decimal points, if appropriate. iarrow_forward1. Write each ordered pair (complex number) in the form: a + bi. а. (2, 6) b. (-7, -3) С. (5, -2) d. (4, 0)arrow_forward
- Please help with this problem. dont round off answer thanks.arrow_forwardFor the given complex numbers: Z1 = 4 - 2i and Z2 = -1 +3i, find: Z1 - 2*Z2 %3D Select one: a. 5- 5i .O b. 6 - 7i O e. 2 + 4i O d.6-8iarrow_forwardPerform the indicated operation & simplify. Express the answer as a complex number. Please do this algebraically (in other words, don't just us a calculator or the computer to do it). Show your instructor in your work that you can do this without technology. (10 + 6i)( – 1- 4i) = BE SURE TO UPLOAD WORKarrow_forward
