Growth rate is the addend by which a quantity increases (or decreases) over time. For example, compound interest is a growth factor situation: If your investment yields 10% annually, then that means that each year, your total has multiplied itself by 110% (the growth factor is 1.10). 

I chose the Chrysler Building which is located in New York and is 1,045 ft. A domino is 5mm so I used the equation 5(1.5)^x.

1.5 is the size difference in each domino, So I did 5(1.5)^13.2 which is 1,055. That means it would take about 13.2 dominos to knock this tower down.

How dominos would it take to knock your building down?

 

 

Imagine All The Numbers

Complex does not mean complicated. A complex number is a combination of a real number and an imaginary number. Real numbers are basically any number you can think of and imaginary numbers when squared give you a negative result.

Ex) Add 3+5i and 4-3i

(3 + 5i) + (4 − 3i)
= 3 + 4 + (5 − 3)i
= 7 + 2i

An electromagnetic field, for example, requires imaginary numbers to measure because the strength of the field is determined by both electrical and magnetic components that must be combined into a single complex imaginary number to get an accurate measurement. Is my example helpful?
