How many edges does a triangular prism have?

The surface area of a triangular prism can be calculated by taking the area of each of the five faces (two triangles and three quadrilaterals) and adding them together.\nThe volume of a triangular prism is the area of one of the triangles multiplied by the length of a quadrilateral (which represents the distance between the two triangles.) According to About.com, the formula is V = (1/2)bhl where b and h are the base and height of a triangle, and l is the length of a quadrilateral.\nA triangular prism is a pentahedron. A pentahedron is a polyhedron with five faces.

How do you solve linear inequalities?

Draw a number line surrounding your constantConsider the example problem x > -8. Draw a horizontal line with an arrow on each end, and mark off small vertical lines for each integer from -12 to -4, getting more positive (and closer to zero) as you move from left to right, to provide plenty of integers on either side of the constant in the problem (-8).Indicate the nature of the inequalityCircle the vertical line corresponding to (-8). Remember that the circle means that the inequality does not include the constant itself as a possible solution. Fill in the circle when the < or > sign has an un..

What is a hyperbola grapher?

Hyperbolas are discussed in conics. A hyperbola has two lines called branches that mirror one another on a graph. Hyperbolas have two foci and two vertices. The foci are further away from the center of the hyperbola than the vertices. A hyperbola is centered on a point, and the closest points on the branches to the center are the vertices. Hyperbolas may be curved or appear nearly straight depending on their eccentricity.

What is the square root of 729?

In this particular example, the square root of 729 is the number that, when multiplied by itself, is equal to 729. If you multiply 27 by 27, you get 729. Also, if you multiply negative 27 by negative 27, you get 729, since multiplying two negative numbers equals a positive number. This is why 729, and any other positive number, will always have two square roots, one positive square root and one negative square root.\nIn math, the root function is the inverse of the exponential function, so the inverse of taking a square root is squaring a number. Using the above example, 27 squared is equal to..

How many edges does a pentagonal pyramid have?

Pyramids are solid geometric figures made up of planar surfaces called "faces" that are bounded by line segments referred to as "edges" or "sides." The points where the edges of the faces meet are called "vertices" or "corner points." The faces are all triangular polygons, which are two-dimensional shapes that are completely enclosed. The intersection point of the lateral faces is called the apex of the pyramid, located above the base. Pyramids are named based on the shape of their bases.The Swiss mathematician Leonhard Euler devised a formula for computing the number of faces, vertices and ed..

What is the parent function of a linear equation?

Linear equations take their name from their graphic representation, graphing the points that apply to the equation yields a straight line, no matter what the equation. The domain and range for a linear equation extend to all real numbers, and the slope of the equation, also known as the rate of change, remains constant. The exponent for the "x" term in the equation is always 1.

How to subtract monomials and binomials?

An example of subtracting a binomial from another is (4*x+8) - (3*x+2). The monomials that contain the variable to the 1st degree can be combined by subtracting 3 from 4, which results in a 1*x term. The single numbers can be combined similarly by subtracting 2 from 8 since both share a variable of x to the zeroth degree. This gives a final expression of 1*x+6.

Who invented exponents?

A general exponential notation, however, was not invented until much later. Mathematicians in the Islamic golden age discovered algebra and worked with equations utilizing powers of two and three. The scholar Omar Khayyam developed a method for finding fourth, fifth and higher roots, but his method was geometric, not algebraic, and did not utilize any kind of exponential or root notation. Nicolas Chuquet, a European mathematician, was the first to use exponential notation and invent the radical symbol to represent roots. His work, "Triparty en la science des nombres," was written in 1484. RenÃ..

What is a base ten model?

The base 10 numbering system is a way to teach kids that each number is 10 times the value of the number to its right. This is where the term base 10 comes from. In the number 574, for example, the 4 is in the ones place, the 7 is in the tens place and the 5 is in the hundreds place.

How do you create an Algebra 2 Trig reference sheet?

List double angle functionsInclude all commonly used double angle functions together on the reference sheet. Such formulas include sin(2x) = 2sinxcosx, cos(2x)\t = cos^2(x) - sin^2(x), tan(2x) = (2tanx)/(1 - tan^2x) and cos(2x) = 1 - 2sin^2(x).Add half-angle functionsIn a separate category, list the common half-angle functions for sin(.5x), cos(.5x) and tan(.5x). For example, the formula for sin(.5x) is equal to plus or minus the square root of 1 - cos(x) divided by 2. List area formulasInclude all area formulas you use in algebra II trig exams. For example, the formula for the area of a trian..
