Answer: B. 130% increase
Step-by-step explanation:
Given function :
If x represents the number of years, we have to determine the two values of y in consecutive terms to determine if the value of y increases or decreases after a year.
This function is equivalent to the exponential growth function
, where A=0.35 and (1+r)=2.3, [A= initial amount , r=annual percent increase]
Thus,
Hence, the annual percent increase is 130%.
Part A: Scatter plot with best-fit line attached. You'll find the line to have equation (approximately)
The positive slope suggests that test scores and study time are directly are proportional.
Part B: Same as in a previous question you had posted. Pick two points on the provided line and compute the slope as best you can. For example, I might pick (2, 30) and (4, 40), which gives a slope of
and assuming the line passes through (2, 30) exactly, it would have equation
