I think it depends on the depends on what result you are looking for if it is the exponential model used in the problem. In this problem, it does show how someone gets this results. Both the exponential growth and decay can be used in exponential functions.
pretty sure its 0.125 and 0.0625 but let me know!
(1/2) / (1 + 2/3) = (4) / (B ) simplify
(1/2) / ( 5/3) = 4 /(B) cross-multiply
B(1/2) = (5/3)(4)
B(1/2) = 20/3 multiply both sides by 2
B = 40/3 cups of B = 13 + 1/3 cups of B
Answer:9%
360,000 / 4000000=.09
.09x100= 9%
Part A: y-intercept = 12 miles
Part B: Find the average rate of change: 36 - 20/2 = 16/2 = 8 mph
This tells us that the bird can travel long distances.
Part C: 172 - 12 = 160 miles at a rate of 8 mph
160 mi ÷ 8mph = 20 hrs
Domain of function = 0 ≤ x ≤ 20
