Answer:
27,000
Step-by-step explanation:
We have been given that after a dose of an antibiotic, the number of bacteria decreases. The equation is 
models this "decay" situation. We are asked to find the original number of bacteria.
We know that an exponential decay function is in form 
, where,
y = Final value,
a = Initial value,
b = Decay factor,
x = Time.
Upon looking at our given equation, we can see that initial value is 27,000, therefore, 27,000 represents the original number of bacteria.
Answer: 2/5m - 1/5
Step-by-step explanation:
2(1/5m - 2/5) + 3/5
2/5m - 4/5 + 3/5
2/5m - 1/5
The answer is a because set of probalitie
Answer:
see explanation
Step-by-step explanation:
Using the Addition/ Subtraction formulae for cosine
Consider the left side
cos(x - y) - cos(x + y)
= cosxcosy + sinxsiny - (cosxcosy - sinxsiny) ← distribute
= cosxcosy + sinxsiny - cosxcosy + sinxsiny ← collect like terms
= 2sinxsiny = right side ⇒ proven
