Quadratic Applications KEY Part 1: Geometry Since area is a square unit‚ often quadratic equations must be used to solve problems involving area. Draw a picture to model each problem. Solve each using any of the following methods: factoring‚ graphing‚ or tables. Show all work. 1. The length of a rectangle is 7 meters more than the width. The area is 60 square meters. Find the length and width. Let x=width and x+7=width

When settlers first came to the New World forests covered ____ per cent of the land. The forests all had a wide range of trees and bushes in them. The "primeval forest" or the first forest Europeans came into contact with had been changed by many acts of nature such as floods‚ hurricanes‚ and flood. Actions of Native Americans also had a hand in changing forests. Such forests included redwood forests‚ which were home to huge redwood trees‚ mossy forests‚ and swamp forests. To many European

depend on the design proposed by the engineer / architect for your home and the prevailing cost of raw materials in the market. Assume that you buy 1200 square feet of land at Rs. 250 square feet. The cost of land is 250x1200 = Rs. 3 lacs. Consider that your house will have 200 square feet of open space and a total construction area of 1000 square feet. There are three categories of construction. A superior finish would cost between Rs. 600-900 per sq. ft.; economy finish Rs. 400-600 sq. ft. and low

Bob would like to know which size of pizza has the lowest cost per square inch. a. Identify the inputs and outputs for this problem. The inputs are the diameters and cost of each of the three different sizes‚ and utputs are the size of pizza with the lowest cost per inch b. Identify the processing needed to convert the inputs to the outputs. Area of each pizza in square inches = pi * (diameter / 2)^2 Cost per square inch = cost / area c. Design an algorithm in pseudocode to solve

Canada The sales of High-pressure laminates (HPL) in Canada went up 38.78 percent from 60 millions of square feet in 1982 to 98 in 1987 (Exhibit 2 in case). However‚ the percentage HPL made in Canada decreased 17 percent that is equal to the percentage HPL imported from US. Obviously‚ most customers start to buy HPL made from US even though the average price of US imports is 1.1 dollars per square foot‚ 0.13 dollar more than the price of Canadian-made.

life of organisms involved and also the size of the area under investigation. For species living in uniform and accessible habitats‚ given their sizes are large enough‚ the population can be estimated by marking and recapture methods‚ or by using square grids of known areas. In some cases‚ when one is dealing with relatively small areas‚ it is possible to isolate the entire population and take a complete census. Although the methods of estimation are different‚ their outlying principles are simple
