Certificate of deposit typical interest rate

This question is too broad because there are many factors that determine the interest rate of a CD, such as the amount you are investing, the length of time, and the banking institution.

Certificate of deposit typical interest rates are usually higher than savings account interest rates. CD's (certificate of deposits) are bound to terms regarding the length someone has to keep their funds in the CD. Unlike a savings account where a person can withdraw their money at just about anytime, a CD has a set time when someone can withdraw money without penalty.

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.
