A class has 20 boys and 15 girls. The teacher randomly selects 4 students to go to the board to solve the exercises. The probability that the 4 selected students are both male and female is ...
Do you think that the matrices we introduced in this discussion are good stand-ins for complex numbers? Explain your reasoning. Is there any operation/task where they might fail to “impersonate” complex numbers? To me matrices are usually harder to solve than doing the work...
Image attached with numbers shown. Using the rectangular form seems like it is the simplest out of the three forms. It's very easy to understand and does not come with as many steps. Personally, I think matrices can be a good stand in for...
I researched Reference and Conterminal angels. Conterminal angels are angles with the same initial and terminal sides. However, the rotations could be different hence the co-terminal. ...
I chose the Pythagorean Theorem for my topic this week. Pythagorean theorem states that "the square of the length of the hypotenuse of a right triangle equals the sum of the squares of the lengths of the other two sides." (Merriam-Webster.com). Another way of saying...
This week, we will learn about trigonometric functions and trigonometry. Trigonometry is applicable in various areas such as engineering, landscaping, physics, and architecture. It can be applied to find the height of buildings and find angle measurements. As you can see, angles are everywhere,...
Hello, Original How do the variables c and d affect the asymptotes? Which transformation rules were applied? In the graph below I changed the C=6 and kept D=-.2 / A=-3.6 / B=3.3 The asymptotes shifted down as a result to increasing C. Also,...
Original Graph moved a to positive 0.9-Right upper left quad shrank or shifted down below the x axis. The lower right quad moved from above the x axis to below the x axis. moved b to negative 1.3 - Horizontal flips...
A rational function is one that can be written as a polynomial divided by a polynomial or the quotient of polynomials. Since polynomials are defined everywhere, the domain of a rational function is the set of all numbers except the zeros of the denominator. The...
