Formula for Compound Interest
Amount = Principal * (1 + Rate/100)^Time
A = P * (1 + R/100)^T
P = A/((1 + R/100)^T) = 92000/((1 + 4.7/100)^16) = $44120.5503
Answer:
What kind?
Step-by-step explanation:
Yes the triangles are similar.
There is a common rate of dilation from the second triangle to the first. Each side can be multiplied/divided by three to find the other length.
I hope is helps.
When we divide complex numbers we divide their magnitudes and subtract their angles, so this isn't all that difficult:


Answer: 
That's probably what's called simplified polar form until you get to Euler's Formula. Since it's 30 degrees we can get a nice rectangular form:

Answer:
The perimeter is 42
Step-by-step explanation:
P=2L+2W is the formula for perimeter and if you use the numbers 42 is the answer
