Na word processing document answer the following question. how could you use descartes' rule and the fundamental theorem of algebra to predict the number of complex roots to a polynomial, as well as find the number of possible positive and negative real roots to a polynomial? your response must include: a summary of descartes' rule and the fundamental theorem of algebra. this must be in your own words. two examples of the process provide two polynomials and predict the number of complex roots for each. you must explain how you found the number of complex roots for each. at least 100 words in complete sentences with appropriate grammar and spelling. provide the source used for information (i. e. the website, the book not providing your source may result in an academic integrity violation. your teacher will use the 2.05b rubric to grade your assignment. select 2.05b rubric to view this rubric. save your assignment as a word processing document (.doc) or rich text format (.rtf) and submit it as assessment 2.05b writing about polynomials.

Which of the following is the result of expanding

Airplane speeds are measured in three different ways: (1) indicated speed, (2) true speed, and (3) ground speed. the indicated airspeed is the airspeed given by an instrument called an airspeed indicator. a plane’s indicated airspeed is different from its true airspeed because the indicator is affected by temperature changes and different altitudes of air pressure. the true airspeed is the speed of the airplane relative to the wind. ground speed is the speed of the airplane relative to the ground. for example, a plane flying at a true airspeed of 150 knots into a headwind of 25 knots will have a ground speed of 125 knots. the problems below refer to static and dynamic pressure. static pressure is used when a body is in motion or at rest at a constant speed and direction. dynamic pressure is used when a body in motion changes speed or direction or both. a gauge compares these pressures, giving pilots an indicated airspeed. in problem #s 1 and 2, use the following information. the indicated airspeed s (in knots) of an airplane is given by an airspeed indicator that measures the difference p (in inches of mercury) between the static and dynamic pressures. the relationship between s and p can be modeled by s=136.4p√+4.5. 1. find the differential pressure when the indicated airspeed is 157 knots. 2. find the change in the differential pressure of an airplane that was traveling at 218 knots and slowed down to195 knots. in problem #s 3 and 4, use the following information. the true airspeed t (in knots) of an airplane can be modeled by t=(1+a50,000) ⋅ s, where a is the altitude (in feet) and s is the indicated airspeed (in knots). 3. write the equation for true airspeed t in terms of altitude and differential pressure p. 4. a plane is flying with a true airspeed of 280 knots at an altitude of 20,000 feet. estimate the differential pressure. explain why you think your estimate is correct.
