When can terms of an algebraic expression be called like terms?
Space and AstronomyIn algebra, like terms are terms that have the same variables and powers. The coefficients do not need to match. Unlike terms are two or more terms that are not like terms, i.e. they do not have the same variables or powers. When can terms be called like terms? “Like terms” are terms whose variables
Why are spring tides stronger?
Space and AstronomyIn both cases, the gravitational pull of the sun is ‘added’ to the gravitational pull of the moon on Earth, causing the oceans to bulge a bit more than usual. This means that high tides are higher and low tides are lower than average. These are called ‘spring tides. ‘ Why are spring tides stronger
What type of planet is Kepler 186f?
Space and Astronomy“This [Kepler-186f] is an Earth-size planet in the habitable zone of a cooler star,” Tom Barclay, Kepler scientist and co-author of the new exoplanet research, told Space.com. “So, while it’s not an Earth twin, it is perhaps an Earth cousin. What type of exoplanet is Kepler-186f? Kepler-186 f is a super Earth exoplanet that orbits
What is a line segment angle?
Space and AstronomyAn Angle is a shape formed by two rays (or two line segments) that meet at a point. We will measure the size of the angle by using degrees. Here are some examples: The right angle shown in the middle is a special case. If two segments or lines meet at a 90 degree angle
What is a cone 3d shape?
Space and AstronomyA cone is a 3D shape consisting of a circular base and once continuous curved surface tapering to a point (the apex) above the centre of the circular base. Is cone a 3D object? 3D objects include sphere, cube, cuboid, pyramid, cone, prism, cylinder. What are the properties of a 3D cone? The three main
What are the 5 postulates of Euclidean geometry?
Space and AstronomyEuclid’s postulates were : Postulate 1 : A straight line may be drawn from any one point to any other point. Postulate 2 :A terminated line can be produced indefinitely. Postulate 3 : A circle can be drawn with any centre and any radius. Postulate 4 : All right angles are equal to one another.
