How do you determine the characteristics of a quadratic function?
Space and AstronomyHow do you determine the characteristics of a quadratic equation? Three properties that are universal to all quadratic functions: 1) The graph of a quadratic function is always a parabola that either opens upward or downward (end behavior); 2) The domain of a quadratic function is all real numbers; and 3) The vertex is the
Which direction should a house face to get the most sun?
Space and AstronomyTo make the most of the sun for warmth and natural light, your home’s main living areas (or any rooms you use a lot) should face north. The main glazing in the house, such as windows and glass doors, should also face north. What direction is best for a house to face? Typically a south-facing
What can a trapezoid also be?
Space and Astronomy1. When can a trapezoid also be called a rhombus? A trapezoid can be called a rhombus when all sides are equal in length. What else can a trapezoid be called? A trapezoid, also known as a trapezium, is a flat closed shape having 4 straight sides, with one pair of parallel sides. The parallel
How do you know if a triangle is HL?
Space and AstronomyIn right triangles, if two legs are congruent and if the two hypotenuses are congruent, then the triangles are congruent. This is known as the hypotenuse leg theorem. How do you tell if a triangle is SSS SAS ASA AAS or HL? Video quote: If we've got that situation where we've got three pairs of
How do you perform operations on complex numbers?
Space and AstronomyTo add two complex numbers , add the real part to the real part and the imaginary part to the imaginary part. To subtract two complex numbers, subtract the real part from the real part and the imaginary part from the imaginary part. To multiply two complex numbers, use the FOIL method and combine like
Why do planets not fall into the sun?
Space and AstronomyWhy planets do not fall into sun? The planets do not fall into the sun because they are moving too fast in the tangential direction. As they fall toward the sun they travel tangentially just enough that they never get very close to the sun. They fall around it, in effect. Why do planets don’t
Can the inverse of a relation that is not a function be a function itself?
Space and AstronomyThe inverse of a function may not always be a function! The original function must be a one-to-one function to guarantee that its inverse will also be a function. A function is a one-to-one function if and only if each second element corresponds to one and only one first element. (Each x and y value
How many habitable planets are there in the Milky Way galaxy?
Space and Astronomy300 million300 million.Oct 20, 2021 Is there a habitable planet in the Milky Way? A paper published in The Astronomical Journal used data from NASA’s now-retired Kepler space telescope to conclude that our galaxy holds an estimated 300 million of these potentially habitable — a rocky planet capable of supporting liquid water on its surface.
How do you find the minimum spanning tree using Kruskal’s algorithm?
Space and AstronomyCreating Minimum Spanning Tree Using Kruskal Algorithm Step 1: Sort all edges in increasing order of their edge weights. Step 2: Pick the smallest edge. Step 3: Check if the new edge creates a cycle or loop in a spanning tree. Step 4: If it doesn’t form the cycle, then include that edge in MST.
What is the relationship between the slope of the line and the side lengths of the triangles?
Space and AstronomyWhat is the relationship between the slope of the line and the side lengths of the triangle? The slope of a line can sometimes be positive or negative. However, the side lengths of each triangle formed are always positive. When a line has a negative slope, the ratio of the side lengths of the triangles
