Does open circle mean parentheses?
Space and AstronomyIs parenthesis open circle? Intervals are either open or closed or both. Open intervals use parentheses ( ) and refer to intervals that do not include the endpoints. Closed intervals use square or box brackets [ ] and refer to intervals that do include the endpoints. What does an open circle mean? Correct answer: A
Can a system of two linear inequalities only have one solution?
Space and AstronomyA system of linear equations usually has a single solution, but sometimes it can have no solution (parallel lines) or infinite solutions (same line). Can a linear inequality have only one solution? Most of the time, an inequality has more than one or even infinity solutions. For example the inequality: x>3 . The solutions of
How hot is Venus for kids?
Space and AstronomyIt’s the hottest planet in our solar system, even though Mercury is closer to the Sun. Surface temperatures on Venus are about 900 degrees Fahrenheit (475 degrees Celsius) – hot enough to melt lead. The surface is a rusty color and it’s peppered with intensely crunched mountains and thousands of large volcanoes. How hot is
What is solar eclipse in short answer?
Space and AstronomyA solar eclipse occurs when the moon gets between Earth and the sun, and the moon casts a shadow over Earth. A solar eclipse can only take place at the phase of new moon, when the moon passes directly between the sun and Earth and its shadows fall upon Earth’s surface. What is solar eclipse
What is tidal heating quizlet?
Space and AstronomyTidal heating is caused by a change in tidal forces. Tidal forces stretch out a solar body. However, another solar object pulls on the solar object causing its orbit to be elliptical. The solar system object is further away from the object it is orbiting at times causing the solar system. object to be less
What are the three layers of the moon?
Space and AstronomyBeneath its thin coating of crushed rock, the Moon has three layers—a crust, a mantle, and a core. As on Earth, the crust is the outermost layer. It averages about 70 kilometers (about 40 mi) thick and contains the least dense type of rock. Beneath the crust is a thick mantle that makes up most
Is a diamond a shape?
Space and AstronomyDiamonds are unique shapes because they have many different geometric attributes. A diamond is a quadrilateral, a 2-dimensional flat figure that has four closed, straight sides. But a diamond is also categorized as rhombus, because it has four equal sides and its opposite angles are equal. Is a diamond shape a square? A simpler explanation
What type of math did the ancient Greeks focus on?
Space and AstronomyWhat type of math did ancient Greece have? The ancient Greek numeral system, known as Attic or Herodianic numerals, was fully developed by about 450 BCE, and in regular use possibly as early as the 7th Century BCE. What type of mathematics are the Greeks known for? Greek mathematicians also contributed to number theory, mathematical
How do you find binary relations?
Space and AstronomyFormally, a binary relation from set A to set B is a subset of A X B. For any pair (a,b) in A X B, a is related to b by R, denoted aRb, if an only if (a,b) is an element of R. How do you calculate binary relations? A binary relation R is
