What is C 2pr?
Space and AstronomyC = 2πr or C = πd. r is the radius and d is the diameter. The diameter is the longest chord that runs through the center of the circle. The radius is the measure of the distance from the center of the circle to a point on the circle. The diameter is 2 times
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

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.

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
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
