If the federal reserve buys a treasury bond from a bank, what will be the effect on the interest rate the bank charges its customers for a loan? a. the interest rate will increase since there are fewer available funds for the bank to loan. b. the interest rate will increase since there are more available funds for the bank to loan. c. the interest rate will decrease since there are fewer available funds for the bank to loan. d. the interest rate will decrease since there are more available funds for the bank to loan.

D.

the federal reserve injects money into banks to give them peace of mind to lower their interest rates. the lower the interest rate, the more people will loan from the bank. this increases the funding to the bank when the loans are paid off so the bank can pay back the reserve while having increased profit

answer; i believe that the correct answer );

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.
