Answer:
- B: The pesticide DDT has a half-life of 15 years.
- C: March Madness has 64 teams in the bracket. Each round, half the teams are eliminated.
- D: After an antibiotic is added to a culture of bacteria, the number of bacteria is reduced by half every three hours.
Step-by-step explanation:
Exponential decay describes a situation in which the dependent variable is reduced by the same factor when the independent variable is increased by the same amount.
A — the population is increasing, not being reduced
B — the amount is cut in half when time increases by 15 years (exp. decay)
C — the number of teams is cut in half when the number of rounds increases by 1 (exp. decay)
D — the amount is cut in half when time increases by 3 hours (exp. decay)
E — the population is increasing, not being reduced

Answer:
It's C
Step-by-step explanation:
y = 7,595.96(1.02)x
the initial beginning value times .02 after adding 1 to it so you would get 1.02 instead since it's an increase raised by x which indicates how many years it was to reach the new value.
Hi there!
Since the slope of a lime that is parallel is always the same, the answer is a. -1.
Since the slope of this equation is -1, the slope of any other parallel line is the same (or else the lines would intersect and not new parallel anymore).
Hope this helps!
1100 miles
this is because u first have to find the miles she drove in january. since she drove 3 times as much in march than in january, u divide or 825 divided by 3 to get 275. since she drove 4 times as much in february of january, u multiply 275 by 4 to get 1100.
hope this helps! :)
