Answer:
<h2>D.
240 strands of bacteria</h2>
Step-by-step explanation:
Given a population culture modeled by the equation P(t) = 15(2)^t/4,
If the population culture begins with 15 strands of bacteria, at t = 0sec, P(t) = 15
if the population doubles after 4hours, this means a t = 4hrs, P(t) =2 * 15 = 30strands
We are to get P(t) when t = 16hours. Substituting t = 16 into the modeled equation we have;
P(16) = 15(2)^16/4
P(16) = 15(2)^4
P(16) = 15(16)
P(16) = 240 strands of bacteria.
Answer:
The answer is A
Explanation:
At first she is very happy holding the broken pieces of the doll but after learning it has a specific name she feels sorrow and regret
25 = -16t^2 + 40t
16t^2 - 40t + 25 = 0
(4t - 5)(4t - 5) = 0
4t - 5 = 0
t = 5/4 = 1.25 seconds.
