Atruck has a minimum speed of 14 mph in high gear. when traveling x mph, the truck burns diesel fuel at the rate of 0.0065413(1024x+x)gal/mile assuming that the truck can not be driven over 56 mph and that diesel fuel costs $1.69 a gallon, find the following. (a) the steady speed that will minimize the cost of the fuel for a 580 mile trip. x= 31366.4 (b) the steady speed that will minimize the total cost of a 580 mile trip if the driver is paid $18 an hour. x= (c) the steady speed that will minimize the total cost of a 360 mile trip if the driver is paid $28 an hour.

The freezing and boiling point of a substance changes as the air pressure around it changes. for example, at a lower air pressure (higher altitude) it is easier for water molecules to escape from liquid into the air. in a high altitude city such as denver, colorado compared to a sea-level city such as houston, texas, water

When a vertical beam of light passes through a transparent medium, the rate at which its intensity i decreases is proportional to i(t), where t represents the thickness of the medium (in feet). in clear seawater, the intensity 3 feet below the surface is 25% of the initial intensity i0 of the incident beam. what is the intensity of the beam "10" feet below the surface? (give your answer in terms of i0. round any constants or coefficients to five decimal places.)
