Hello,
f(1)=160
f(2)=160*(-2)
f(3)=160*(-2)²
f(4)=160*(-2)^3=-1280
f(n)=160*(-2)^(n-1)
3 times the 6th power of 10
Lets step by step convert the word form to an expression
You have to multiply 3 by the 6th power of 10, so
3 * 6th power of 10
In the 6th power of 10, 10 is the base and it is to the power of 6, so it can be reworded to 10 to the 6th power
or 
We have to multiply it by 3
So the written expression is
3 *
Not sure sorry edit : oh sorry I was suppose to add this in the comment section
Answer:
Variable A and variable B have a negative linear association.
Step-by-step explanation:
We are asked to find which best describes the association between variable A and variable B.
From the scatter plot we could clearly see that as the value of variable A are increasing the corresponding value of variable B is decreasing.
Also we could see that the points are linear.
Hence, the relationship that best describes variable A and variable B is:
Negative linear Association
