What is the definition of transformation in geometry?
Space and AstronomyWhat is a transformation in math definition? A transformation is a general term for four specific ways to manipulate the shape and/or position of a point, a line, or geometric figure.

How many linear feet are in a circle?
Space and AstronomySquare the radius: 10^2 = 100 square feet. Multiply the result by pi, which equals approximately 3.142: 3.142 x 100 = 314.2. This answer is the circle’s linear footage. A theoretical single board with a 1-foot width would need to be about 314 feet long to equal the circle in area. How many feet are

How does multiplicity affect a graph?
Space and AstronomyThe multiplicity of a root affects the shape of the graph of a polynomial. Specifically, If a root of a polynomial has odd multiplicity, the graph will cross the x-axis at the the root. If a root of a polynomial has even multiplicity, the graph will touch the x-axis at the root but will not

What causes impact craters?
Space and AstronomyCraters produced by the collision of a meteorite with the Earth (or another planet or moon) are called impact craters. The high-speed impact of a large meteorite compresses, or forces downward, a wide area of rock. The pressure pulverizes the rock. Why are so few impact craters found on Earth? So why are there so
