Answer:
700 foundations is the answer
Answer:
5,000,000,000 or 1,953,125,000,000,000
Depends on what you mean
Step-by-step explanation:
If (5*10)^9
(50)^9
1,953,125,000,000,000
Or if 5 * (10)^9
5 * 1,000,000,000 = 5,000,000,000
Answer:
slope= 3/5 y int=-2 equation y = 3/5 -2
Step-by-step explanation:
slope= rise over run
y int = where the y axis and the line meet
equation= y =mx+b
m=slope
b = y int
Answer: Hello there!
We know that the culture has 2000 bacteria initially (at t = 0 min), and it doubles when t = 40min, again at t = 80 min, and so on
And the rate of grouth is proportional to the population, then we can obtain an expression of the form:
P(t) = 2000*k(t) where k(t) is the factor that defines the growth of the population:
we know that:
p(0) = 2000*k(0) = 2000
p(40) = 2000*k(40) = 2000*2 = 4000
p(80) = 2000*k(80) = 2000*2*2 = 8000
etc
then we can see that k(t) = 2^(t/40)
where k(0) = 1, k(40) = 2, k(80) = 2*2, etc
then the function that models the population of the culture is:
p(t) = 2000*2^(t/40)
where t is in minutes.
Take the Square root of both sides
(nearest tenth)
