UW Smokestacks has a chimney which needs cleaning regularly. Soot builds up on the inside of the chimney at a rate of 1cm per month. The cost of cleaning when the soot has thickness x cm is 13 + x2 hundred dollars. Cleaning can occur at the end of any month. The chimney is clean at present (i. e. at the start of month 1). According to the contract with the cleaners, it must be cleaned precisely nine times in the next 48 months, one of which times must be at the end of month 48. Also, at least three cleanings must occur in the first 15 months.
It is needed to determine which months the cleaning should occur, to minimize total cost. Formulate a nonlinear mathematical program to solve this problem, such that all constraints are either linear or integrality constraints.

The instruction ishl (shift left integer) exists in jvm but not in ijvm. it uses the top two values on the stack, replacing the two with a single value, the result. the sec- ond-from-top word of the stack is the operand to be shifted. its content is shifted left by a value between 0 and 31, inclusive, depending on the value of the 5 least signifi- cant bits of the top word on the stack (the other 27 bits of the top word are ignored). zeros are shifted in from the right for as many bits as the shift count. the opcode for ishl is 120 (0x78).a. what is the arithmetic operation equivalent to shifting left with a count of 2? b. extend the microcode to include this instruction as a part of ijv.

Assume that to_the_power_of is a function that expects two int parameters and returns the value of the first parameter raised to the power of the second parameter. write a statement that calls to_the_power_of to compute the value of cube_side raised to the power of 3 and that associates this value with cube_volume.
