How is graph theory used today?
Space and AstronomyGraph theory is used to find shortest path in road or a network. In Google Maps, various locations are represented as vertices or nodes and the roads are represented as edges and graph theory is used to find the shortest path between two nodes. How is graph theory used in real life? In the real-world,
What is the Arcsin of 4?
Space and AstronomyTable of remarkable values arcsin(-1) -π2 arcsin(0) 0 arcsin(12) π6 arcsin(√22) π4 arcsin(√32) π3 How do you solve arcsin 4? Video quote: From minus 90 degrees to positive 90 degrees. And since we have a minus 4 over 5 that puts us the theta in a quadrant 4 here's angle quadrant 4 sine of this

Can negative numbers be negative when squared?
Space and AstronomyAnswer: No, the square of an integer can never be a negative number. The square of a number can be found by multiplying a number by itself. Explanation: If we find the square of an integer, say a, then a × a = a2. Can a negative number squared be negative? Video quote: And a

How many linear feet are in a circle?
Space and AstronomySquare the radius: 10^2 = 100 square feet. Multiply the result by pi, which equals approximately 3.142: 3.142 x 100 = 314.2. This answer is the circle’s linear footage. A theoretical single board with a 1-foot width would need to be about 314 feet long to equal the circle in area. How many feet are
