Write VBA code such that when a command button named cmdmath is clicked: i) A value is retrieved from a text box (state the name that you choose for this text box), and stored in a variable named x. ii) A value is retrieved from a text box (state its name), and stored in a variable named y. iii) The variables x and y are concatenated (i. e., "tacked together"), and the result is displayed in a label (state its name). iv) The mathematical expression: is evaluated, and the result is displayed in a second label (state the name). Do not use the same label for both results. Example: if x

Technician a says that the radiator usually cools better if the front air dam is removed. technician b says that when a condenser has a leak it can be repaired easily with epoxy. who is correct?

When making changes to optimize part of a processor, it is often the case that speeding up one type of instruction comes at the cost of slowing down something else. for example, if we put in a complicated fast floating-point unit, that takes space, and something might have to be moved farther away from the middle to accommodate it, adding an extra cycle in delay to reach that unit. the basic amdahl's law equation does not take into account this trade-off. a. if the new fast floating-point unit speeds up floating-point operations by, on average, 2ă—, and floating-point operations take 20% of the original program's execution time, what is the overall speedup (ignoring the penalty to any other instructions)? b. now assume that speeding up the floating-point unit slowed down data cache accesses, resulting in a 1.5ă— slowdown (or 2/3 speedup). data cache accesses consume 10% of the execution time. what is the overall speedup now? c. after implementing the new floating-point operations, what percentage of execution time is spent on floating-point operations? what percentage is spent on data cache accesses?

Anul 2017 tocmai s-a încheiat, suntem trişti deoarece era număr prim, însă avem şi o veste bună, anul 2018 este produs de două numere prime, 2 şi 1009. dorel, un adevărat colecţionar de numere prime, şi-a pus întrebarea: “câte numere dintr-un interval [a,b] se pot scrie ca produs de două numere prime? “.
