explain a sustainable construction technique for each of the following issues: i) Energy ii) Materials iii) Waste Energy – Solar panels are a great sustainable construction technique. If they are placed in the right areas and face at the right angle these solar panels can harness a lot of energy from the sun. This energy can then be used to heat water‚ power lights or any other form of appliance which needs electricity. There is an initial cost to purchase and install the solar panels which can

Buried Treasure MAT 221 Instructor Date Buried Treasure In this essay of Buried Treasure we will use many different ways to attempt to factor down three expressions problems. Our first problem from our reading talks about Ahmed and Vanessa‚ Ahmed has half of a treasure map‚ which indicates that the treasure is buried in the desert 2x + 6 paces from Castle Rock. The other half of the map is in Vanessa possession and her half indicates that to find the treasure‚ one must

etc to be in the correct place‚ they should have matte surface to avoid reflection glare. The desk should also be low enough to allow you to keep your forearms horizontal and high enough to allow your thighs to go under it. Elbows should be at an angle of at least 90 degrees with sitting at it. The chair must be high enough to allow you to sit comfortably over the keyboard‚ it should be a swivel chair with five castors so it will ensure that the chair is stable.

Write the equation of a line parallel to the given line but passing through the given point. y=1/2x+1; (4‚2) Locate the parallel Line by using the ordered pair (4‚2) Multiply ½ by x to come up with x/2 Now we have y = x/2 + 1 Let’s use the formula y = mx + b whereas m equals slope and equals the y-intercept. Right now we know that m = ½ when using the above formula So in order to find the equation which is parallel to y + 1/2(x + 1) the slopes will have to be equal. We must incorporate
