What is the formula for an isosceles trapezoid?
Space and AstronomyThere are several dedicated isosceles trapezoid area formulas: bases a,b and height h given: A = (a + b) * h / 2. bases a,b and leg c given: compute h via the Pythagorean Theorem ( h is the square root of c² – (a-b)²/4 ) and A = (a + b) * h /
How does the Parkes radio telescope work?
Space and AstronomyParkes has a parabolic dish antenna, 64 m in diameter with a collecting area of 3,216 m2. The dish is made up of aluminium panels supported by a lattice-work of supporting struts. To incoming radio waves from space, the dish surface acts in the same manner as a smooth mirror. How does a radio telescope
What is the rule for adding and subtracting algebraic terms?
Space and AstronomyTo add two or more monomials that are like terms, add the coefficients; keep the variables and exponents on the variables the same. To subtract two or more monomials that are like terms, subtract the coefficients; keep the variables and exponents on the variables the same. What is the rule of addition in algebra? In
Can two collinear rays intersect?
Space and AstronomyCan collinear lines intersect? Logically in any collinear intersection situation it seems reasonable to just return any point within the overlapping region – it also seems to be reasonable to return every point in the overlapping region – it also seems reasonable to return no points at all (the argument being that collinear intersection is
What time does the moon set in Hawaii?

How do you know if an interval is positive or negative?
Space and AstronomyHow do you know if a interval is positive or negative? Video quote: So positive intervals would be those that lie above the x axis. And negative intervals would be those that lie below the x axis. How do you know which interval is positive? At x equals a or at x equals b the
What is calculus for science?
Space and AstronomyHow is calculus used in science? In physics, for example, calculus is used to help define, explain, and calculate motion, electricity, heat, light, harmonics, acoustics, astronomy, and dynamics. Einstein’s theory of relativity relies on calculus, a field of mathematics that also helps economists predict how much profit a company or industry can make. Is calculus
Is the Incenter always inside the triangle?
Space and AstronomyYes, the incenter is always inside the triangle. It is the point forming the origin of a circle that is inscribed inside the triangle. Just like a centroid, an incenter is always inside the triangle and it is made by taking the intersection of the angle bisectors of all three vertices of the triangle. Can
How big is the comet in Deep Impact?
Space and AstronomyThe film depicts the attempts to prepare for and destroy a 7-mile (11 km) wide comet set to collide with Earth and cause a mass extinction. What is the size of the comet in Deep Impact? On July 1 of that year, Deep Impact rendezvoused with Comet 9P/Tempel 1 (the official name is usually shortened
What is m3 size?
Space and AstronomyWhat does M3 mean in size? cubic metre A cubic metre (often abbreviated m3 or metre3) is the metric system’s measurement of volume, whether of solid, liquid or gas. It forms part of the SI Unit’s (Systeme International d’Unites) measurement system and can be thought of as a solid cube having 1m-long sides, thereby giving
