Which of the following assumptions made in deriving the simple deposit multiplier is unrealistic? the fed sets the required reserve ratio. the fed is able to affect the level of reserves in the banking system. banks loan out all of their excess reserves. the simple deposit multiplier is equal to 1 divided by the required reserve ratio.

Banks loan out all of their excess reserves.

Explanation:

It is virtually impossible for a bank to loan all the money it has (deducting required reserves) since loans are handed out every day and are also repaid every day. It is a constant flow, where clients are constantly getting new loans (or refinancing old loans) or repaying existing loans. The only way that a bank could loan all its available money would be that the bank has only a few clients that simultaneously get large loans, but that would carry huge risks.

bd = 9 cm

step-by-step explanation:

in a 30°-60°-90° triangle, the ratio of side lengths is 1 : √3 : 2. that is, the longest side (hypotenuse) is twice the length of the shortest side.

all of the triangles in your geometry are 30°-60°-90° triangles. ac is the hypotenuse of δacd, and the short side of δabc.

the short side ad of δacd will be half the length of ac, so 3 cm. the hypotenuse ab of δabc will be twice the length of ac, so 12 cm. segment bd is the difference of the lengths ab and ad, so is

bd = ab -ad

bd = 12 cm - 3 cm = 9 cm

comment on side length ratios

you can figure the ratios of side lengths in a 30°-60°-90° triangle by considering the trig ratios of the angles. or you can figure the length of the altitude of an equilateral triangle of side length 2 using the pythagorean theorem.

years agooo ahaha. but honestly they need to update ! : )
