Admission to an aquarium is $14 per person. There is also an IMAX theatre in the building, which charges $8 per ticket for a 3D shark show.

Which equation can be used to find x, the length of the hypotenuse of the right triangle? A triangle has side lengths 63, 16, x. 16 + 63 = x 16 squared + 63 = x (16 + 63) squared = x squared 16 squared + 63 squared = x squared

For a 2 Vpp signal that fits within the ADC's input range, find the SQNR for: a) an 8-bit ADC with an input range of 1V to 6V b) a 9-bit ADC with an input range of 0V to 4V

A payload is to be delivered by airdrop. The vertical velocity at landing has to be less than 7m/s. The total weight of the payload and parachute system is 400kg. Determine the minimum diameter of the open parachute, assuming a drag coefficient Cd 1.

A completely reversible heat pump produces heat at a rate of 100 kW to warm a house maintained at 25℃. The exterior air, which is at 0℃, serves as the source.

A closed system undergoes a process in which work is done on the system and the heat transfer Q occurs only at temperature Tb. For each case, determine whether the entropy change of the system is positive, negative, zero, or indeterminate.
