Since i = 2% is the monthly rate, we multiply 2% x 12, the number of monthly periods in a year in order to determine the annual rate. In this case, Aaron needs to find an interest rate of 24% per year compounded monthly in order to reach his future value goal of $634 in one year.
Enamel is the thin outer covering of the tooth. This tough shell is the hardest tissue in the human body. Enamel covers the crown which is the part of the tooth that's visible outside of the gums. Because enamel is translucent, you can see light through it.But the main portion of the tooth, the dentin, is the part that's responsible for your tooth color -- whether white, off white, grey, or yellowish.lthough enamel is a hard protector of teeth, it can chip and crack. Enamel also insulates the teeth from potentially painful temperatures and chemicals. Unlike a broken bone that can be repaired by the body, once a tooth chips or breaks, the damage is done forever.
The good news is, cosmetic dentistry can rebuild broken and worn down teeth and restore them to their original length, shape and function.
