Answer:
+ 15 is the integer measure.
Step-by-step explanation:
We have given yard that means the length since, yard is unit measure.
Integer are those numbers which do not have fractional part.
They are not in the form of rational number that is not in the form of 
Yard is a unit of linear measure.
Yard is equal to 3 feets.
Answer:
a. an = -1 • 4^(n - 1)
Step-by-step explanation:
It's easy see that each term is multiplied by 4 to get the next term, so the common ratio will be 4, that reduces the choices to answers A and B (since C and D use -1 as common ratio). Also, normally a geometric progression uses "n-1", so we'll first try with A to see if it works.
a1 = (-1) * 4^0 = -1 * 1 = -1
a2 = (-1) * 4^1 = -1 * 4 = -4
a3 = (-1) * 4^2 = -1 * 16 = -16
Yes, it works... so the answer is an = -1 • 4^(n - 1)
Answer: 200
Step-by-step explanation:
You have 2000 and 1/10 is the same as divide by 10 so:
2000/10 = 200
