The length of BC would be 6ft
Remember, SF= new/old. On shape 2, the side with the length 3 corresponds to the length of 9 on shape 1. (SF=3/9)=0.3333333....
Notice that each day the number of kernels doubles, then we can model that behavior with the following equation:

Where N is the number of kernels on the nth day.
Evaluating the above function at n=26 we get:

Answer: 33554432.
Answer:
The answer is a =3/4 and 5/18
Step-by-step explanation:
When you are trying to figure this out put them into a list vertically. Remember, ONE X CAN'T HAVE TO Y's BUT ONE Y CAN HAVE MULTIPLE X's, But dont worry about the y's right now. Lets focus on the x's.
Ask yourself, Are there 2 or more x's that are the same value?
Yes) Continue to next step
No) It's a function :)
If there are 2 or more of the same x value, ask your self now if those x's have different y Values.
Yes) It is not a function, one x can not have more that 1 y value
No) Its a function :)
