Vertex Figures and Arrangements

Find (and describe) all the regular tessellations of the plane. Note that septagons, nonagons, and 11-gons are not provided. How do you know each one you find really fills in all the gaps around a vertex point? How do you know when you're done? (2) Find (and describe) all the semiregular tessellations of the plane ( you will ...continues

Determining the area of a circle segment within a circle

The spreadsheet attachment provides all of the givens and we are asked to determine the central angle, length of a chord, and the area of the identified circle segment?

Find the symmetries of the regular tessellations in a plane

square- we are to explain reflection: how many lines( 2 edges, 2 bisectors, vertex arrangement is order is 4 90degrees, rotation :center of shape is order 4, midpoint is order 2 180. triangle- reflection 6lines(3edges and 3 bisectors), vertex arrangement is very similar to hexagon but(please explain) order 6 (60 degrees) ...continues

Discussion question

Some people believe that calculators have eliminated the need to learn the skills to perform mathematical operations by hand. State your position on this belief, and then support your position with real-life stories or examples

An overview on tessellations.

An overview of the theory and results on tessellations of three types of Riemann surfaces: the Euclidean plane, the sphere and the hyperbolic plane. Roughly speaking, a tessellation of a space is a pattern which, repeated infinitely many times, fills the space without overlaps or gaps . From a mathematical point of view, tesse ...continues

Determining Probability - During the last hour, a telemarketer dialed 20 numbers and reached 4 busy signals, 3 answering machines, and 13 people. Use this information to determine the empirical probability that the next call will be answered in person. ...

1. During the last hour, a telemarketer dialed 20 numbers and reached 4 busy signals, 3 answering machines, and 13 people. Use this information to determine the empirical probability that the next call will be answered in person. 2. If you roll a die many times, what would you expect to be the relative frequency of rolling ...continues

The objective of statistics is best described as: a) To make inferences about a sample based on information we get from a population b) To use population mean, m as an estimate of the sample mean, c) To make inferences about a population based on information we get from a sample taken from the population d) To make inf ...continues

Transformation of the graph of a function

See file for an example from textbook. I plugged in x^2 + 6x + 10 into my calculator and got the required graph and the answer of -3 units parallel to the x-axis. But how does one come to this answer of -3units 'manually' without using a calculator? Thank you.
