The temperature in the office room is 22 degrees centigrade. We should protect the environment. O Mario is 24 years old. When the burner beneath a pot of water on the stove is turned on the water will heat up.

The Anderson County board of supervisors has agreed to fund an ambitious project that will spend money now to save much more money in the future. A total of $16.2 million will be awarded to the York Corporation for energy improvements in 40 buildings, 27 parks, and 37 traffic intersections. These improvements include lighting upgrades, solar hot water collectors, more efficient heating/cooling systems, and light-emitting diodes for traffic signals. Bonds paying 7% per year over the next 15 years will be used to pay for these improvements. If the annual savings fail to average $2 million, York Corporation will reimburse the county the difference. Will York need to pay any money to the county? If so, how much?

Which of the following statements is correct regarding Kepler's three laws of planetary motion? Angular momentum of any planet about an axis through the Sun and perpendicular to the orbital plane is not invariant during its motion. Planets move in elliptical orbits with the sun not being at its center. Orbital period of a planet is directly proportional to Which of the following statements is correct regarding Kepler's three laws of planetary motion? Angular momentum of any planet about an axis through the Sun and perpendicular to the orbital plane is not invariant during its motion. Planets move in elliptical orbits with the sun not being at its center. Orbital period of a planet is directly proportional to its distance from the sun. Kepler's laws are valid only for planets in the solar system.

Gasoline-contaminated groundwater has flowed under a residentialdwelling from a nearby gasoline station. Two meters beneath the 100m2 dirt floor of the residential basement, theconcentration of hydrocarbon vapors in the soil air is 25 ppm on amass/mass basis. Estimate the flux density of gasoline vapor andthe daily rate of vapor transport into the basement by moleculardiffusion. Assume an approximate diffusion coefficient of10-2 cm2/sec for gasoline vapor inthe soil and, the basement is well ventilated, so that the gasolinevapor concentration in the basement is much less than 25 ppm. Airdensity is approximately 1.2 g/1000 cm3 at 1atm pressure and 20˚C.

Consider the quadric surface given by 314 22 – 216 x y - 48 x z + 404 y2 + 72 yz +250 22 = 3025 (a) Express this equation in the form x? Ax = 3025 where A isa symmetric matrix and x = y Enter the matrix A in the box below a ab sina 8 a 12 E aac (b) You are given that the matrix A has eigenvalues 242, 242 and 484. Hence the equation of the surface in terms of its principal exes X, Y and Z can be written as 242 x 2 +242 Y2 + 484 22 = 3025 Enter the shortest distance, in Maple syntax, from the origin to the surface in the box below. Note: Use sqrt command when necessary.

Many companies are undergoing server virtualization. This is the concept of putting multiple “virtual” servers onto one physical device. The payoffs can be significant: fewer servers, less electricity, less generated heat, less air conditioning, less infrastructure and administration costs, increased flexibility, less physical presence (that is, smaller server rooms), faster maintenance of servers, and more. There are costs, of course, such as licensing the virtualization software, labour costs in establishing the virtual servers onto a physical device, labour costs in updating tables, and access. But determining the return on investment can be a challenge. Some companies have lost money on server virtualization, while most would say that they have gained a positive return on investment but have not really quantified the results. (a) How might a company really determine the return on investment for server virtualization? (b) Is this a project that a systems analyst might be involved in? Why or why not?
