What is the functions minimum or maximum value?
Space and AstronomyFinding max/min: There are two ways to find the absolute maximum/minimum value for f(x) = ax2 + bx + c: Put the quadratic in standard form f(x) = a(x − h)2 + k, and the absolute maximum/minimum value is k and it occurs at x = h. If a > 0, then the parabola opens

What did Benjamin Banneker Discover?
Space and AstronomyIn 1752, Banneker garnered public acclaim by building a clock entirely out of wood. The clock, believed to be the first built in America, kept precise time for decades. In 1789, Banneker began making astronomical calculations that enabled him to successfully forecast a solar eclipse. What did Banneker Benjamin invent? In 1753, Banneker created his

What makes a sun?
Space and AstronomyThe Sun is a huge, glowing sphere of hot gas. Most of this gas is hydrogen (about 70%) and helium (about 28%). Carbon, nitrogen and oxygen make up 1.5% and the other 0.5% is made up of small amounts of many other elements such as neon, iron, silicon, magnesium and sulfur. How are suns created?

What is linear combination in linear algebra?
Space and AstronomyIn mathematics, a linear combination is an expression constructed from a set of terms by multiplying each term by a constant and adding the results (e.g. a linear combination of x and y would be any expression of the form ax + by, where a and b are constants). What is linear combination with example?

Is there an angle side side Theorem?
Space and Astronomyfirst such theorem is the side-angle-side (SAS) theorem: If two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, the triangles are congruent. Following this, there are corresponding angle-side-angle (ASA) and side-side-side (SSS) theorems. What is the angle side angle theorem? The Angle-Side-Angle Postulate

How do you find the sides of an octagon with diameter?
Space and AstronomyMultiply the diameter’s length, the distance from vertex to opposite vertex, by 0.383 to calculate a side’s length. For example, the diameter is 10 inches — 10 inches multiplied by 0.383 results in 3.83 inches. How do you find the sides of an octagon? Video quote: And if I happen to call this distance right
