What is the difference between constructing a square and constructing a regular hexagon?

a. the diameter of the circle is used for the square construction, but the radius of the circle is used for the regular hexagon construction.
b. the radius of the circle is used for the square construction, but the diameter of the circle is used for the regular hexagon construction.
c. the square will need two arcs along the circle, but the hexagon will need two arcs above and two arcs below the diameter of the circle.
d. the square will need six arcs along the circle, but the hexagon will need two arcs above and two arcs below the diameter of the circle.

Plzzz asap what is the inverse of f if f(x)=^3 sqrt x-5

Asmall (but heavy) particle placed in a glass of water will follow a zigzag motion because the particle will bounce off of the water molecules it meets. this is called brownian motion. a physicist simulates this on a computer, by varying the distance a particle can travel (called the mean free length), on average, before it collides with a water molecule and assigning the change in motion to be one of 8 directions, each with a similar probability. by running the simulated particle (with the same mean free length) many times she determines that it should take 15 seconds, on average, for the particle to fall to the bottom, with a standard deviation of 1.5 seconds. next she lets a real particle fall through a glass of water and finds that it took 18 seconds. what does she conclude, and why?

An optical inspection system is used to distinguish among different part types. the probability of a correct classification of any part is 0.92. suppose that three parts are inspected and that the classifications are independent. let the random variable x denote the number of parts that are correctly classified. determine the probability mass function of x. round your answers to four decimal places (e. g. 98.7654). x f(x) 0 1 2 3
