8. ( 10) Review the documentation and videos on Combinations and permutations available in the lesson. Use the permutation formula or the combination formula as appropriate to a. Given a class of 5 students in how many ways can we select a committee of 3 students b. Given a class of 5 students in how many ways can we select a President, and a treasurer

the correct is answer is a 9-sided polygon!

6 spoons of sugar for every 21 cups of flour

step-by-step explanation:

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
