Can two lines be concurrent?
Space and AstronomyDefinition. When two or more lines pass through a single point, in a plane, they are concurrent with each other and are called concurrent lines. A point that is common to all those lines is called the point of concurrency. How do you know if two lines are concurrent? Three or more lines in a
What are 3d shapes and their properties?
Space and Astronomy3D shapes have faces (sides), edges and vertices (corners). Faces. A face is a flat or curved surface on a 3D shape. For example a cube has six faces, a cylinder has three and a sphere has just one. Edges. An edge is where two faces meet. … Vertices. A vertex is a corner where
When would you use perspective view in lieu of an isometric drawing?
Space and AstronomyWhen would an isometric view be more appropriate than a perspective view? isometric means equal measurement, i.e., each of the three planes of the cube is equally fore-shortened. This projection is more appropriate in the case of small objects, but larger objects may appear to be unnatural. Perspective projection is used to represent larger objects.
Is Procyon B habitable?
Space and AstronomyThough dim and diminutive, Procyon B and other white dwarf stars like it could host planets sporting mild temperatures, oceans and living critters. What will happen to Procyon B? As it continues to expand, the star will eventually swell to about 80 to 150 times its current diameter and become a red or orange color.
What are advanced functions math?
Space and AstronomyWhat are advanced functions? Advanced functions is just that: it takes your knowledge of functions and rates of change further. For example, in the grade 12 Advanced Functions course you’ll look at the following: Exponential and logarithmic functions. Trigonometric functions. What kind of math is advanced functions? Advanced Functions, Grade 12, University Preparation (MHF4U) You
What is a function in a set of ordered pairs?
Space and AstronomyA function is a set of ordered pairs in which no two different ordered pairs have the same x -coordinate. An equation that produces such a set of ordered pairs defines a function. What is the catch? There can be at most one output for every input. How do you tell if a set of
Why are Saturn’s rings visible?
Space and AstronomySaturn’s rings are largely water ice, and so they reflect more sunlight back to us. Jupiter’s rings, have lower proportions of ice, and lots of smaller dust particles that tend to scatter light forward rather than back to us. Why are Saturn’s rings visible from Earth? Although reflection from the rings increases Saturn’s brightness, they
Will the solar eclipse be visible in the US?

The next solar eclipse occurs October 2, 2024.… Solar eclipse of April 8, 2024 Map Type of eclipse Nature Total Gamma 0.3431 Will the USA see the
What are characteristics of the asteroid belt?
Space and AstronomyThe asteroid belt is a torus-shaped region in the Solar System, located roughly between the orbits of the planets Jupiter and Mars. It contains a great many solid, irregularly shaped bodies, of many sizes, but much smaller than planets, called asteroids or minor planets. What are some characteristics of the main belt structure? Most of
What does a rigid motion preserve?
Space and AstronomyRigid motion – A transformation that preserves distance and angle measure (the shapes are congruent, angles are congruent). Which of the following does a rigid motion preserve? Rigid motions preserve collinearity. Reflections, rotations, and translations are all rigid motions. So, they all preserve distance, angle measure, betweenness, and collinearity. What do rigid motions do? Rigid
