3.03 Periodic Trends Julianne Mazzaro 1. Refer to the graph that you created in Part I of this assignment. Describe the general trend or patterns that you observed in the atomic radius as you go across the periodic table. As the number of protons (atomic number) gets bigger, the atomic radius gets smaller. The largest decrease in size was from 3 to 4, and it leveled out after the 5 to 6 decrease.
Pick any three problems and find the difference. a. x2 –144 b. 64x2 –81 c. 36x2 –49y2 d. x4 –1 e. 81x4 –1 4. Factor a perfect square trinomial. Pick any two problems and factor each perfect square trinomial.
Complete the table below to compare their advantages and disadvantages. [pic] 12. With regard to the Land Ordinance of 1785, which became the official survey system for the United States, define the following: a) township b) sections ● CONTEMPORARY TOOLS 13. Geographers use a GIS (Geographic Information System) to store “layers” of data. Give three examples of types of data stored in a single layer.
Radicals Tips 1. Make sure that one of the two factors of the radicand (expression under the radical) is the largest perfect square: Example: Simplify 72 Correct 72 = 36 ∙ 2 = 62 Incorrect 72 = 9 ∙ 8 = 38 2. To be able to add or subtract radicals, the radicands must be the same. Example 1: Add 32 + 52 Answer: Since radicands are the same, (3 + 5)2 = 82 Example 2: Subtract 73 - 3 Answer: (7 – 1)3 = 63 Example 3: 318 - 52 (Must simplify first) 39 2 - 52 3 ∙ 3 ∙ 2 - 52 92 - 520 Answer: 42
So the radian is the measure of how close a degree is to a complete circle. * How do special right triangles directly relate to the unit circle? There are two types of special right triangle, 90, 60, 30 and 45, 45, 90. With both triangles, the angles of degrees are directly related to the x and y values on the unit circle. With the case of 90, 60, 30 and 90, 45, 45, the angles are relative to the sin of its value on the unit circle.
Calculate the area (in square miles) of the white space, which is a quarter of a quarter of a section at: NE 1/4, NE 1/4, S 24, T3N, R2E? (6 points) A: 1/16 sq mile CONTOUR LINES 4. What is the contour interval on this map? (4 points) A: The contour interval on this map is 20. 5.
C Lines of latitude measure the distance north and south of the ____. D a collection of maps in a book atlas Which of the following is the correct definition of a continent? D Which of the following is an example of latitude? B ____ is part of the United States but is not a contiguous section of the country. NOT C What is one way geographers use special purpose maps?
Some students believe that the Earth’s tilt changes in degree as the seasons change and that the axis points in different directions as the Earth orbits the Sun. In reality the Earth’s axis is always tilted at 23.5 degrees and the North Pole always points toward Polaris (Lambert, 2010). Most of the planets in the solar system have nearly circular orbits, much like Earth. The orbits do, however, have an elongated shape. The orbits of Mercury and Pluto are very elongated whereas the orbits of the other planets are almost circular (Nelson, 2005).
For an irregular face, a V-map is produced based on the intersection of the entire normal-vectors through Boolean operation. Since the number of normal-vector is unlimited, determining the optimal number for an irregular face still becomes challenging issue among researchers. To reduce the number of normal-vector, an irregular face is then converted into regular faces through 2 different common methods. Convert it into stereolithography (STL) or divide it into small triangles by facet triangular meshing method. Huifeng, et al [6], using triangle facets from STL model to determine V-map of an irregular face.
