Need help solving this in MATLAB

Questions Question 1 (5 points) The equivalent resistance, Req, of four resistors, R1, R2, R3, and R, that are connected in parallel is given by: 4 R1 R2 R3 R4 Calculate Re if R1250, R2 1502, R3 1752, and R4 502 Include your m code here: Include a screen capture of your command window's output here Resources used to solve this problem: Question 2 (5 points) The voltage Vc t seconds after closing the switch in the circuit shown is Given Vo-36 V, R-2000Q, and C-2400F, calculate the current 8 seconds after the switch is closed. Be careful about your inputs - make sure you are converting from the metricw system to a decimal number - you may have to look up what the micro in front of the F means!] Include your .m code here Include a screen capture of your command window's output here Resources used to solve this problem: Question 3 (5 points) Create a vector (call it vctC) that has 12 elements of which the first is 5, the increment is 4, and the last element is 49. Then, by assigning elements of this vector, create the following new vectors. A vector (name it Codd) that contains all the elements with odd index of yctC i.e., Codd-5 13 21. 45. a) b) A vector (name it Ceven) that contains all the elements with even index of vctC; i.e., Ceven In both parts, try to use vectors of odd and even numbers for the index of Codd and Ceven, respectively. Do not type the elements of any vector explicitly. Extra credit opportunity: If you can create Codd and Ceven without explicitly referring to every entry, you will receive a 2 point bonus.] Include your .m code here: Include a screen capture of your command window's output here: Resources used to solve this problem: Question 4 (5 points) Create the following matrix by using vector notation for creating vectors with constant spacing and/or the linspace command. Do not type individual elements explicitly. 130 110 90 70 50 30 10 1 2.8333 4.6667 6.5 8.3333 10.1667 12 62 72 12 22 32 42 52 Include your .m code here Include a screen capture of your command window's output here: Resources used to solve this problem: Question 5 (5 points) Using only the zeros, ones, and eye commands, create the following arrays by typing in one command for each part. a) b) lo o 0 0 1 Include your .m code here Include a screen capture of your command window's output here Resources used to solve this problem: Question 6 (5 points) The radus, r, of a sphere can be calculated from its surface area, s, by:r= Tani .
