Answer:
f(1) = 8
Common ratio: 0.5
Step-by-step explanation:
f(1) means the firs term in a sequence.
In the function f(n), represented by 8, 4, 2, 1, .., the first term is 8.
f(1) = 8
To find the common ratio, divide any term by the term before it.
We can use any two of the given terms in the sequence EXCEPT for 8 because it is the first term and does not have a term before it.
I choose to divide the second term by the first term:
4/8 = 1/2 = 0.5
Answer: D) 12
The factors of 12 are: 1, 2, 3, 4, 6, 12
The factors of 36 are: 1, 2, 3, 4, 6, 9, 12, 18, 36
The greatest common factor is 12.
we are given
![25ft+25ft+20ft+20ft+2.5ft+2.5ft+8ft+13ft](https://tex.z-dn.net/?f=%2025ft%2B25ft%2B20ft%2B20ft%2B2.5ft%2B2.5ft%2B8ft%2B13ft%20)
Since, every value is in ft
so, we can take out ft
![=(25+25+20+20+2.5+2.5+8+13)ft](https://tex.z-dn.net/?f=%20%3D%2825%2B25%2B20%2B20%2B2.5%2B2.5%2B8%2B13%29ft%20)
now, we can add them
and we get
