What are shapes defined by?
Space & NavigationIn 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 & NavigationWhat 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

How does the new moon occur?
Space & NavigationBottom 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

What is the highest point of an orbit called?
Space & NavigationThe 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
