Let r1 and r2 be the "divides" and "is a multiple of" relations on the set of all positive integers, respectively. thatis, r1 ={(a, b)|adividesb}andr2 ={(a, b)|a is a multiple of b}. find

a. r1 ∪r2.

b. r1 ∩r2.

c. r1 −r2. d)r2−r1. e)r ⊕r. 1 2

false

step-by-step explanation:

rulers and compasses arent required in order to bisect an angle because when bisecting angles, you're making a "half circle" and considering in order to bisect an angle it wouldn't be straight, you wouldn't need either of the two

to determine the unit cost your would divide the total cost by the number sold.
