The powers of 2 ( 20=1 , 21=2 , 22=4 , etc) arise frequently in computer science. (For example, you may have noticed that storage on smartphones or USBs come in powers of 2, like 16 GB, 32 GB, or 64 GB.) Use np. arange and the exponentiation operator ** to compute the first 30 powers of 2, starting from 2^0. Hint 1: np. arange(1, 2**30, 1) creates an array with 230 elements and will crash your kernel.

Match the terms in the hlookup syntax with their explanation. a. lookup value b. data table c. row index d. mode 1. name of the table that contains the value 2. specifies if an exact match must be found 3. value to be searched 4. name of the row that contains the value

Me2540 week 5 assignment what do i want to know?

Me with this program in c++ ! computers represent color by combining sub-colors red, green, and blue (rgb). each sub-color's value can range from 0 to 255. thus (255, 0, 0) is bright red. (130, 0, 130) is a medium purple. (0, 0, 0) is black, (255, 255, 255) is white, and (40, 40, 40) is a dark gray. (130, 50, 130) is a faded purple, due to the (50, 50, 50) gray part. (in other word, equal amounts of red, green, blue yield gray).given values for red, green, and blue, remove the gray part. ex: if the input is 130 50 130, the output is: 80 0 80. thus, find the smallest value, and then subtract it from all three values, thus removing the gray.
