How do bounding boxes work?
Space and AstronomyA bounding box is an imaginary rectangle that serves as a point of reference for object detection and creates a collision box for that object. Data annotators draw these rectangles over images, outlining the object of interest within each image by defining its X and Y coordinates. How is a bounding box predicted? Each grid
Does Earth go through phases like moon?
Space and AstronomyEarth shows phases, just like the Moon does for terrestrial observers. The phases, however, are opposite; when the terrestrial observer sees the full Moon, the lunar observer sees a “new Earth”, and vice versa. How would the phases of Earth appear to you compared to the phases of the Moon as seen from Earth? When
What is a trapezoid in real life?
Space and AstronomyThe blade of the shovel forms the shape of a quadrilateral that has a pair of parallel lines and a pair of non-parallel lines. Hence, it is a clear example of trapezoid-shaped objects in real life. What is a real life example of a trapezoid? While some people think the trapezoid is a term reserved
How do teachers use kahoot?
Space and AstronomyYou can host a kahoot live to teach in class or remotely, or assign a student-paced challenge. When playing live in class, kahoots are displayed on a shared screen everyone in the classroom can see. Students join in and answer using their own device with an internet connection – for example, a tablet or computer.
What is the parent function of a radical function?
Space and AstronomyRadical Functions The parent function of a square root function is y = √x. Its graph shows that both its x and y values can never be negative. This means that the domain and range of y = √x are both [0, ∞). The starting point or vertex of the parent function is also found
What came first the telescope or microscope?
Space and AstronomyIt is thought that the microscope came first and, since a microscope can simply be reversed to make a telescope, this could be how the latter originated. What is clear is that both were in use in Holland by the end of the sixteenth century and that Galileo purchased his first telescope around 1607. When

How do you solve R in C 2pir?
Space and AstronomyHow do you find r in 2pir? Video quote: But for the radius what we do is we take this circumference we get R by itself we divide through by 2 pi. And we end up with radius is equal to circumference divided by 2 pi. What is the formula to solve for r? Video
