9514 1404 393

Answer:

  C.  10 units

Step-by-step explanation:

The distance MN can be found using the distance formula.

  d = √((x2 -x1)² +(y2 -y1)²)

  d = √((2 -(-4))² +(3 -(-5))²) = √(6² +8²) = √100 = 10

The distance from M to N is 10 units.

In how many different ways can a man divide 7 different gifts among his 3 children if the eldest is to receive 3 gifts and the o
krok68 [10]

The order in which gifts are received doesn't matter - if child X gets toy 1 then toy 2, it's the same as giving child X toy 2 then toy 1 - so we are counting combinations.

The eldest child receives 3 of the 7 gifts, so they have

\dbinom 73 = \dfrac{7!}{3!(7-3)!} = 35

possible choices of gifts.

The next child receives 2 of the remaining 4 gifts, so they have

\dbinom 42 = \dfrac{4!}{2!(4-2)!} = 6

choices.

The last child receives the remaining 2 gifts, and there is only

\dbinom22 = \dfrac{2!}{2!(2-2)!} = 1

way to select the gifts for them.

By the multiplication using, the total number of ways of distributing 7 gifts among 3 children in the prescribed way is 35 • 6 • 1 = 210.

“How did Faulkner pull it off?” is a question many a fledgling writer has asked themselves while struggling through a period of apprenticeship like that novelist John Barth describes in his 1999 talk "My Faulkner." Barth “reorchestrated” his literary heroes, he says, “in search of my writerly self... downloading my innumerable predecessors as only an insatiable green apprentice can.” Surely a great many writers can relate when Barth says, “it was Faulkner at his most involuted and incantatory who most enchanted me.” For many a writer, the Faulknerian sentence is an irresistible labyrinth. His syntax has a way of weaving itself into the unconscious, emerging as fair to middling imitation.

While studying at Johns Hopkins University, Barth found himself writing about his native Eastern Shore Maryland in a pastiche style of “middle Faulkner and late Joyce.” He may have won some praise from a visiting young William Styron, “but the finished opus didn’t fly—for one thing, because Faulkner intimately knew his Snopses and Compsons and Sartorises, as I did not know my made-up denizens of the Maryland marsh.” The advice to write only what you know may not be worth much as a universal commandment. But studying the way that Faulkner wrote when he turned to the subjects he knew best provides an object lesson on how powerful a literary resource intimacy can be
