How do I know if my roots are complex?
Space and AstronomyThe Fundamental Theorem of Algebra assures us that any polynomial with real number coefficients can be factored completely over the field of complex numbers . In the case of quadratic polynomials , the roots are complex when the discriminant is negative. What are considered complex roots? Complex roots are the imaginary root of quadratic or
How do you read a micrometer practice?
Space and AstronomyHow do you read a micrometer step by step? Video quote: The portion of the micrometer that points to the main scale is actually the edge of the thimble the edge of the rotating part. What are the four steps for reading a micrometer? 5.4: How to Measure With Micrometer Supplies: Step 1: Take the
Is division of real numbers commutative?
Space and AstronomyAddition and multiplication are commutative. Subtraction and division are not commutative. Is division commutative or not? The commutative property states that the numbers on which we operate can be moved or swapped from their position without making any difference to the answer. The property holds for Addition and Multiplication, but not for subtraction and division.
How do you name a sector of a circle?
Space and AstronomyTo name a sector, use one arc endpoint, the center of the circle and then the other arc endpoint. How do you write the name of a sector? Video quote: If the radius of a circle is R. And an arc a be on the circle subtends an angle X degrees at the centre o.
Do vector components have direction?
Space and AstronomyA vector quantity has two characteristics, a magnitude and a direction. How do you find the direction of a vector in components? Video quote: So if this is the angle theta. Then the component of a along the direction of B is a cosine theta. So the easiest way of doing this problem is to
What causes impact basins to form?
Space and AstronomyHow are impact basins formed? Multiring structure, Valhalla-type: They show many multiple rings and little basin topography today. They are formed by near instantaneous collapse of the cavity and sublithospheric flow due to the presence of a ductile layer at shallow depths (Hiesinger and Head 2003). What causes an impact crater to form? Craters produced
Are all parallel lines congruent?
Space and AstronomyThey are always congruent. Same-side Interior Angles: Angles in between the parallel lines and on the same side of the transversal. They are always supplementary. Same-side Exterior Angles: Angles that are outside on different sides of the two parallel lines, but are on the same side of the transversal. Can parallel lines be congruent? If
How do you write a rational equation?
Space and AstronomyTo write a rational expression in lowest terms, we must first find all common factors (constants, variables, or polynomials) or the numerator and the denominator. Thus, we must factor the numerator and the denominator. Once the numerator and the denominator have been factored, cross out any common factors. How do you write a rational function
How many morphemes in goes?
Space and AstronomyHow many morphemes in the word goes? goes is only two morphemes. The es is a morpheme that communicates, in this case, that the verb before it is present tense, third person singular. Is going 1 or 2 morphemes? Senior Member. “Gonna”/”going to” is practically one morpheme, even in adult speech. I would count it
What is the angle angle theorem?
Space and AstronomyThe Angle-Angle Similarity Theorem states that if two angles in one triangle are equal to two angles in another triangle, then the triangles are similar. What is the angle angle side theorem? The Angle-Side-Angle Postulate (ASA) states that if two angles and the included side of one triangle are congruent to two angles and the
