Can a graph of a rational function have no vertical asymptote?
Space and AstronomyNot all rational functions will have vertical asymptotes. Algebraically, for a rational function to have a vertical asymptote, the denominator must be able to be set to zero while the numerator remains a non-zero value. How do you graph a rational function with no vertical asymptotes? Video quote: Remember our definition of domain the set

How do you find the range of a function in Algebra 1?
Space and AstronomyTo find the domain and range, we simply solve the equation y = f(x) to determine the values of the independent variable x and obtain the domain. To calculate the range of the function, we simply express x as x=g(y) and then find the domain of g(y). How do you find the range of a

How are celestial bodies classified?
Space and AstronomyCelestial bodies or heavenly groups are objects in space such as the Sun, planets, Moon, and stars. They form a part of the massive universe we live in and are typically very far from us. How do you classify celestial bodies? Classification of Celestial Bodies Stars. Stars are giant balls of hot gases that can

What will improve the resolution of a telescope?
Space and AstronomyIncreasing the diameter of the objective lens. Decreasing the diameter of the objective lens. How can I increase the resolution of my telescope? The resolution of the telescope does not get any better. For better resolution, you need a larger aperture telescope with a high-quality lens or mirror. Let’s look at this same area of

What is an interval on a graph?
Space and AstronomyAn “interval graph” is the graph showing intersecting intervals on a line. So, we associate a set of intervals E={E1,…,En} on a line with the interval graph G=(V,E), where V={1,…,n} and two vertices, x and y, are linked by an edge if and only if Ex⋂Ey≠∅. What does interval mean on a graph? Video quote:

Are consecutive angles of a trapezoid supplementary?
Space and AstronomyWe already know (thanks to our extensive background in working with parallel lines) that consecutive interior angles are supplementary, so we’ve proven that consecutive angles in a trapezoid that share the same leg are supplementary. Are consecutive angles always supplementary in a trapezoid? In a trapezoid, the two angles that are on the same leg

How do you find the probability of a circle graph?
Space and AstronomyTo get the probability, we simply add their slices together to see what proportion of the area of the pie chart is in that region: 36% + 25% + 20% = 81%. We can also add sections together even if they do not touch. How do you find probability on a graph? Therefore, probability is

What is the formula for the volume of a trapezoidal prism?
Space and AstronomyFormula for Volume of a Trapezoidal Prism. If the prism length is L,trapezoid base width B, trapezoid top width A, and trapezoid height H, then the volume of the prism is given by the four-variable formula: V(L, B, A, H) = LH(A + B)/2. In other words, multiply together the length, height, and average of

What color is the nighttime sky?
Space and AstronomyWithout an atmosphere the sky appears black, as evidenced by the lunar sky in pictures taken from the moon. But even a black sky has some lightness. At night, the sky always has a faint color, called “skyglow” by astronomers. What is the color of sky at night? The color of the sky is blue

Why is a pink moon pink?
Space and AstronomySo although April’s full moon is known as the Pink Moon, don’t expect it to look particularly pink! It’s named after pink flowers called wild ground phlox, which bloom in early spring and appear throughout the United States and Canada. Why is it called a pink moon?
