The object below was made by placing a cone on top of a cylinder. The base of the cone is congruent to the base of the cylinder.1) What is the volume, in cubic centimeters, of the object? Explain how you found the volume of the (2) smaller shapes.2) Then explain how you found the volume of the total shape.**Do not just show your answer. Explain your steps and the numbers you used.**Did you use radius? height? diameter? base? Pi (3.14)?

4 Permutations 1. Let a "small block cipher be a function f which maps 8-bit plaintexts m E (0,1)8 to 8-bit ciphertexts c E (0,1)8. However, function f must be 1-1 or otherwise it would be impossible to invert a block cipher, i.e. compute (using the block cipher key) the plaintext f(c) given ciphertext c. How many "small" block ciphers are there? students if each student must have a computer and computers cannot be shared? capital letters but with no repeated characters? 2. There are 10 computers and 5 students. In how many ways can computers be assigned to 3. Recall problem 1. How many 8-character passwords are there made of either lower-case or . How many 10-digit decimal strings are there in which there is no repeated digits? 5. How many 10-digit decimal strings are there in which there is no repeated digits and where 5" occurs before "6"? (By "before" I mean "anywhere before" and not "mmediately before", e.g. string (5,0, 1, 2, 3, 4, 7, 8, 9, 6) is included.) 6. How many 10-digit decimal strings are there in which there is no repeated digits and where "5" and "6" are next to each other?

UESTION 2 120 MARKS Underground cable breakdown often occur due to the unpredictable deterioration rate of the cable insulation. Cable replacement can be very costly without regular mainte A 9-month study on an underground cable insulation had been conducted to check for the length of the cable insulation that have been deteriorated using fluorescence microscope in order to estimate the maintenance cycle. Table 1 shows the data measured every 3 months during the study Table 1 Time, t (month) Deteriorated cable insulation length, I 1.35 3.72 7.28 15.45 (a) Generate a third order polynomial using Newton's interpolation method to describe the variable of the deteriorated cable insulation length, (t) with respect to time (in month). Write the polynomial in the form of At3BtCt D, where [10 marks] A, B, C and D are constants. (b) According to regulation, the cable insulation requires replacement if it is degraded by 6 mm. Calculate the replacement time using Newton Raphson method with initial guess of 6 months from the polynomial generated in part (a). Perform THREE iterations only and calculate true percent relative error for the final iteration answer [10 marks if the true value of the replacement time is 5 months.
