In 2010, tara used $50,000.00 from funds she had invested in certificates of deposit as a down payment to buy a house. what function did this portion of her investments serve when she made the down payment?
a. unit of exchange.
b. medium of exchange.
c. store of value.
d. unit of account.

B. medium of exchange.

Explanation:

Money as a medium of exchange is used to facilitate the selling and purchasing of goods and services between parties. Money is widely accepted as a standard of value by parties engaged in the exchange of commodities. It means that one party readily accepts an amount of money in exchange for a product or service that is believed to be worth the amount on offer.

Tara is exchanging her $50,000 for the house. Although the money is only a down-payment, it gives her the right to claim ownership of the house. Once she has fully paid for the house using money, she can only lay a claim on the house,  not the money.

don't use it that much

start by isolating the variable on one side by adding 43w^2 to both sides.   the equation will read:

25w^2+5=0

*subtract 5 from both sides*

25w^2=-5

*divide both sides by 25*

w^2=-1/5

*take the square root of both sides*

w=√(-1/5)

the square root of -1 is i.   the square root of 5 remains √5

the answer is i/√5.

hope this
