- What is the value of each of the following Boolean expressions? 54 3=3 2+45 6==7 2+4=6 3+4==4+3 1!=2 2!=2 5==72 3+9=0arrow_forward"NEED ONLY CODE NO EXPLANATION" Harry has a big wall clock, that got hit while he was playing. Now, the minute hand doesn't rotate by the angle 2π/3600 each second, but now it moves according to different angle x. You can assume that coordinates of the centre of the clock are (0, 0) and the length of the minute hand is l. One endpoint of the minute hand is always located at the clock centre; the other endpoint is initially located at the point (0, l). One second later, Harry observes that this endpoint is at distance d above the x-axis, i.e., the y-coordinate of this endpoint is equal to d. Harry is curious about where the minute hand will be (specifically, its y-coordinate) after t seconds. Because t can be very large, Harry can't wait for that moment.

- (Financial application: find the profit-per-item) You have just started a new stationary shop. Your profit-per-item depends on the total quantity of item sold. The scheme shown below is used to determine the total profit: Quantity Profit-per-item 0-1000 $1 1001-5000 $2 5001 and above $5 Note that this is a graduated profit. The profit for selling up to 1000 items is $1, for next 4000 items is $2 and beyond that is $5. If the total quantity of item sold is 10000, the profit is 1000 * $1 + 4000 * $2 + 5000 * $5 = $34000. Your goal is to make $50,000 a year.
