Question

Group Project Financial Planning A local dym just went corporate, so you decide to investigate its profitabit to see if it stock is worth buying. The gym collect a flat toe of 50 per month from each of its 63 members, but it's maintenance expenses are $170 per month plus an additional $0.15 every time someone uses the gym. The gym has created a solid model they use to predict how much use they get over the year U(m) = 97.com) +513 where U (m) is the number of times the gym is used during monthm (1 for January, 2 for February, etc.) Use this model alongside the gym's pricing and expenses to create a function describing the gym's expected profit och month. Does the gym look like a good investments Group Prolect-Movie Magic You're back in the quirky scientist's lab. The team is now studying a radio transmission from the alien spaceship. You need a nice, fancy sine wave to put on your scientist's holo computer. The display field you're working with is 41 high and 8ft wide. You don't want to fill the whole field, so you decide to leave a foot on each end. You also want to make sure you include ten oscillations of the radio wave in the image. What amplitude should you use for the sine wave? What period? Please write out the full function you intend to use for your display. Group Project - Chemistry Applications The efficiency of the chemical synthesis you wish to perform varies with temperature, and unfortunately your building's air handler is on the fritz. You're at the whims of nature now, so you need a good model of your town's temperature throughout the day. Yesterday the lowest temperature reached was 48°, while the highest temperature reached was 62°. The weather report doesn't say what time of day those temperatures Occurred at, but you do remember that your car reported an outside temperature of 55° while you were driving to work at 8:30am. Use this information to construct a model of the day's temperature and use it to predict the temperature you'll encounter at 3pm today.

Answer 1

Change in temperature during the day= Q/c*m where Q is the heat change in joules, c is specific heat capacity of water and m is the mass
