So, say order mattered. If we had x toppings and we only wanted groups of two different toppings, we would have x toppings for the first option, and x-1 toppings for the second option since we've already used a topping. Using the multiplication rule that would give us x(x-1) different groups, if order mattered, which is written as:
So, in this specific problem order does not matter. We see that we've overcounted because for every pair of toppings we have, they can be reordered 2!=2 ways. So that means we must divide by two to get:
Which is written as:
The equation in slope intercept form is y= 1x - 70
The sine function is increasing in the first quadrant.
sin(0) = 0
sin(90) = 1
This means the larger angle will give a larger sine value.
sin(w) > sin(t) -----> w > t
Declarative. It is a statement that ends in a period (.)
