The place you get your hair cut has two nearly parallel mirrors 7.00 apart. as you sit between these mirrors in the chair, your head is 2.50 from the mirror in front of you. looking toward this mirror, you first see your face and then, farther away, the back of your head. side note: the mirrors need to be slightly nonparallel for you to be able to see the back of your head, but you can treat them as parallel in this problem. neglect the thickness of your head. 1.how far away does the back of your head appear to be? (from you)

Explanation:

Given:

By the laws of reflection we know that the image of an object appears at the same distance from the surface of a plane mirror as that of the object from the surface of the mirror.

Now the distance of the head from the rear mirror:

Now the distance of image of the back of head in the rear mirror from the object head:

Now this image is reflected into the front mirror from the image of the back of the heat in the rear mirror.

So, this is the second reflection of the actual object, which will form at a distance of:

elly's long hair:

a. if the salon only takes cash, then this isn't the problem. it doesn't matter how much she has in her checking account.   she can't get a haircut until she has the cash.

b. if she has overdraft protection, then there's no problem.   she can go ahead and write a check that her account can't cover, then sometime later, pay the bank some outrageous usury for loaning her a few bucks for a few days, but with beautiful hair.

c. if elly has some principles, and doesn't want to write a bad check, then now she has a problem.   her desire for the new hairstyle is in conflict with her honesty and integrity.

d.   if the bank will not process a check she writes, then even if she had a million $$ in her account, she couldn't use any of it.   the amount she has in her account is not the problem.   and if i may suggest, she might as well close her checking account, and put the money where it'll work for her.   it's not doing her a bit of good in a checking account, since she can't write any checks.

justin can't pay the full balance:

a. he can't even handle the credit limit he has now.   under no circumstances should he ask for a higher limit.

b.   he can ask for the grace period to be extended.   but that's no solution, the bank will almost certainly refuse anyway, and there are much better options.   he knew the rules of his credit card when he started using it.

c.   he definitely should pay the interest on the balance, plus as much of the balance as he can cover at the same time.

d.   he definitely should pay the minimum otherwise they could shut down his card.   he should also pay as much more as he possibly can.   he should also remember the awkward situation he's in, stop buying stuff on credit that he can't afford, and avoid adding any more debt.

i'd say that justin's best best option isn't on this list of choices.   what he has to do:   pay as much as he can at least the minimum payment plus as much more as he can and then avoid adding more debt.
