Answer:
When given a percentage of growth or decay, determined the growth/decay factor by adding or subtracting the percent, as a decimal, from 1. In general if r represents the growth or decay factor as a decimal then: b = 1 - r Decay Factor. b = 1 + r Growth Factor. A decay of 20% is a decay factor of 1 - 0.20 = 0.

Answer:
0.833 feets
Step-by-step explanation:
Given that:
Volume of box = 1600
Heigh of box (H) = 8 inches
Let:
Width of box (W) = x
Length of box (L) = 2x
Volume of box = (Height * width * length)
1600 = (8 * x * 2x)
1600 = 16x²
x² = 1600/16
x² = 100
x = sqrt(100)
x = 10 inches
Hence, width of box in feet:
1 inch = 0.0833 feets
10 inches = (10 * 0.0833) feets
= 0.833 feets
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%.
