And length of minor axis = 2b = 2*10 = 20. c) From part a) and b), we have a = 8 and b = 10 and h=3,k=-5 So, c2=b2-a2=102-82=100-64=36 =>c=sqrt36= 6. In this given equation b>a So, this is a vertical ellipse. Therefore, coordinates of foci = (3, -5+6) and (3, -5-6) Foci are (3,1) and (3, -11). d) This is the graph of given ellipse with foci and center. (12 points) Score | | 2.
Unit 11 – AO1 – The Universe and the Big Bang Introduction - This AO explores the parts that make up the universe and how these parts tie in to each other to make up the world we live in. Check List - This assignment requires the following tasks to be completed: 1. Features of the Universe * The Universe * The Big Bang Theory * Stars * Galaxies * Constellations * Nebulae * Planets * Asteroids * The Sun 2. Life Cycle of a Star * Explain each of the 6 stages of a star’s life cycle. Include the name given to the star for each stage 3.
Interpret the result. F(0)=0.48in(X+1+27 x=e^(25fo/12-56.25)-1 F(100)=.48in(X+1)+27 x=e^(625f/3-56.25)-1 b. At what distance from the eye of the hurricane is the air pressure 28 inches of mercury? 80 miles 8. Describe the quotient rule for logarithms using an example.
Leavitt’s discovery of the period-luminosity relation for Cepheid variable stars In the early 1900’s Henrietta Leavitt’s extensive research on Cepheid Variable stars enabled her to determine the relationship between the period and luminosity of stars to determine their distance from earth. Variable stars emit lights in different intensities and are also known as “lighthouse stars”. There is a direct relationship these stars have, which has a significant role in establishing the distance from earth, of stars that are in excess of 100 light years away (Mitchell, 1976, 162). This is the relationship between luminosity and the pulsation period of these stars. With luminosity being a measure of brightness and pulsation period being the time

10/7/2013 Capella Capella is the brightest star in the constellation Auriga, the sixth brightest star in the night sky and the third brightest star in the northern celestial hemisphere. Capella is the brightest yellow star in our sky after the Sun. Although it appears to be a single star to the naked eye, it is actually a star system of four stars in two binary pairs. The first pair consists of two bright, large type-G giant stars, both with a radius around 10 times the Sun's, in close orbit around each other. These two stars are thought to be cooling and expanding on their way to becoming red giants.
