The crowding-out effect refers to the possibility that: a. a deficit, financed by borrowing in the capital markets, will increase the interest rate and reduce investment in the private sector.
b. an increase in the supply of money will induce a decline in real spending.
c. when used simultaneously, expansionary fiscal and monetary policies are counter-productive.
d. the speculative demand for money varies inversely with the interest rate.

a. a deficit, financed by borrowing in the capital markets, will increase the interest rate and reduce investment in the private sector.

Explanation:

Crowding out effect is when government borrowing from the capital markets leads to an increase in interest rate. this makes it more expensive for private sector to borrow and this reduces investment by private sector

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.

answer; /// the above statement is (true); good luck
