What is the relationship between interest rates and aggregate spending? A.
when interest rates increase, aggregate spending also increases
B.
when interest rates increase, aggregate spending decreases
OC. they do not have any relation
OD
both the factors are affected favorably by any external factor
O E.
both the factors are affected adversely by any external factor

B. when interest rates increase, aggregate spending decreases

Explanation:

Interest rates and aggregate spending have an inverse relationship. An increase in interest rates results in a decrease in aggregate expenditure. Interest refers to the cost of money, while aggregate spending is the total consumption in the economy.

When the cost of money is high, firms and households will stop borrowing, which reduces spending. It means businesses will not expand, and domestic consumption reduces. The net effect is a lower demand for goods and services, resulting in lower aggregate spending.

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.
