Is Apothem the same as radius?
Space and AstronomyThe apothem of a regular polygon is a segment connecting the center of the polygon to a midpoint of one of the sides, and the radius of a regular polygon is a segment connecting the center of the polygon to one of the vertices. Is radius an apothem? An apothem of a regular polygon will

What is the mathematical sign for parallel?
Space and Astronomy∥∥, so we can say that A B ↔ ∥ C D ↔ \overleftrightarrow{AB}\parallel\overleftrightarrow{CD} AB ∥CD in that figure. According to the axioms of Euclidean geometry, a line is not parallel to itself, since it intersects itself infinitely often. What is the mathematical symbol for parallel? Geometry Symbol Chart Symbol Symbol Name Meaning/definition of the

Why Venus is hottest planet than Mercury?
Space and AstronomyThe carbon dioxide traps most of the heat from the Sun. The cloud layers also act as a blanket. The result is a “runaway greenhouse effect” that has caused the planet’s temperature to soar to 465°C, hot enough to melt lead. This means that Venus is even hotter than Mercury. Why is Venus the hottest

Are cork oak trees deciduous?
Space and AstronomyUnlike many other oak trees, cork oak is an evergreen and does not drop its leaves. Can cork trees grow in the United States? Cork trees are relatively common in the western United States, where they are available from numerous nurseries. Some of the more prominent examples are found at the UC Davis campus and

What is a critical point of a function?
Space and AstronomyHow do you find the critical points of a function? To find the critical points of a function y = f(x), just find x-values where the derivative f'(x) = 0 and also the x-values where f'(x) is not defined. These would give the x-values of the critical points and by substituting each of them in

How do you plot a graph on XY?
Space and AstronomyCartesian points are written as xy pairs in parentheses, like so: (x, y). To graph a point, first locate its position on the x-axis, then find its location on the y-axis, and finally plot where these meet. How do you write XY coordinates? Coordinates are written as (x, y) meaning the point on the x

How do you solve supplementary and complementary angles?
Space and AstronomyIf we know that a set of angles form one of these special relationships, we can determine the measure of the other angle. To determine the supplement, subtract the given angle from 180. 180 – 43 = 137° The supplement of 43° is 137°. To determine the complement, subtract the given angle from 90. How

What does an armillary sphere do?
Space and AstronomyAn armillary sphere is basically a skeletal celestial sphere with a model of the Earth or, later, of the Sun placed in the center. It is useful as a teaching tool and as an analog computer for solving various astronomical problems to a crude degree of accuracy. How does a armillary work? How does an

What is a dependent event in probability?
Space and AstronomyDependent events: Two events are dependent when the outcome of the first event influences the outcome of the second event. The probability of two dependent events is the product of the probability of X and the probability of Y AFTER X occurs. What is an example of a dependent event in probability? Dependent events in

How do you describe an angle bisector?
Space and AstronomyAn angle bisector is a line or ray that divides an angle into two congruent angles . In the figure, the ray →KM bisects the angle ∠JKL . How can you explain angle bisector? Angle bisector in geometry refers to a line that splits an angle into two equal angles. Bisector means the thing that
