How do you find the domain of X?
Space and AstronomyFunctions assign outputs to inputs. The domain of a function is the set of all possible inputs for the function. For example, the domain of f(x)=x² is all real numbers, and the domain of g(x)=1/x is all real numbers except for x=0. We can also define special functions whose domains are more limited. What is

What is SSA congruence rule?
Space and AstronomyWhat is the SSA Congruence Rule? The SSA congruence rule states that if two sides and an angle not included between them are respectively equal to two sides and an angle of the other then the two triangles are equal. Why is SSA not congruent? Knowing only side-side-angle (SSA) does not work because the unknown

What is the absolute extrema in calculus?
Space and AstronomyAbsolute extrema are the largest and smallest the function will ever be and these four points represent the only places in the interval where the absolute extrema can occur. How do you find the absolute extrema? To find the absolute extrema of a continuous function on a closed interval [a,b]: Find all critical numbers c

What are shapes defined by?
Space and AstronomyIn geometry, a shape can be defined as the form of an object or its outline, outer boundary or outer surface. What makes a shape shape? At its most basic, a shape is created when a line is enclosed: a line forms the boundary, and the shape is the form circumscribed by that boundary. Line

What is an undefined expression?
Space and AstronomyWhat does it mean when expression is undefined? An expression that is undefined means that the denominator of the expression is equal to zero. Therefore, the expression cannot be determined at that value. What is an example of an undefined expression? A rational expression is undefined when the denominator is equal to zero. To find

What is the highest point of an orbit called?
Space and AstronomyThe mountain represents the highest point in the orbit. That’s called the apoapsis. The altitude affects the time an orbit takes, called the orbit period. What is the lowest point of an orbit called? The low point of the orbit is called the perigee. The high point of the orbit, when the satellite is moving

How does the new moon occur?
Space and AstronomyBottom line: New moon occurs when the moon is on the same side of Earth as the sun. New moons generally can’t be seen. They cross the sky with the sun during the day, and the moon’s shadow side is pointed toward Earth. A new moon is visible only during a solar eclipse. How often

How water is produced in Mars?
Space and AstronomyHow is water produced in the Mars? Water is produced by burning fuels on Mars. Can water be created on Mars? Breakthrough Invention Makes Water on Mars Useful to Humans, Colonizing Possible. Scientists have recently confirmed that there used to be (and still is) abundant water on Mars. Is water on Mars drinkable? Scientists have

Why is a Monomial a polynomial?
Space and AstronomyMonomials include numbers, whole numbers and variables that are multiplied together, and variables that are multiplied together. A polynomial is a sum of monomials where each monomial is called a term. Is a monomial a polynomial? A monomial, or two or more monomials combined by addition or subtraction, is a polynomial. Some polynomials have special

How dense is the Sun’s radiative zone?
Space and AstronomyThe Solar Structure Internal Structure Inner Core Density: 1.622×105 kg/m3 Temp: ~1.57×107 K Radiative Zone Density: 20 g/cm3 to 0.2 g/cm3 Temp: Approx. 7×106 to 2×106 K Convection Zone Surface and Atmosphere Is the radiative zone density? Matter in a radiation zone is so dense that photons can travel only a short distance before they
