Q1 Which of the following statements is true if x (a character array) is added (+) to a y (2 x 2 double)? Select one: a. Variable x will be converted into a double and then concatenated with y to create new ASCII-type variable b. The addition operation (+) cannot be performed c. Variable y will be converted into a string and then concatenated with x to create a new string-type variable d. ASCII values of x are added to y to create a new double-type variable e. It is equivalent to the statement x == y and creates a logical-type variable Q2 Consider the following non-linear equation where x is the independent variable, y is the dependent variable, and A and B are constants. Which of the following is the resulting gradient variable in linearised form? Select one: a. B b. log10(B) c. log(-A) d.

Please code in python Kiki is making “Happy National Pizza Day” (February 9th) cards for all of her friends. She’s a bit disappointed with the cards not looking special enough, so she decides to add glitter to them to make them look more special. However, she’s short on glitter, so she decides to add glitter selectively. She uses a box with N*N divided sections to store her cards. Each section is huge and each card is small, so she can put multiple cards in a given section and they will never overlap. We model the way that she organizes the cards and adds glitter using two commands: Command 1: 1 x y: add a card to the box in section (x, y). Command n: 2 x1 y1 x2 y2: Add one unit of glitter to each of the cards in the sections from (x1, y2) to (x2, y2). Help Kiki determine the total number of units of glitter that she placed on the cards. Input The first line will contain N (1 <= N <= 500) and C (1 <= C <= 500 ), the square size of the card storage box…
python - Recap: X is an array from -3pi to 8pi in 1000 steps. Write the python syntax for looping over all values of X and updating the value current to -999. where X is an even multiple of pi. Hint, use a for loop and appropriate if statements.
