Answer:
n = 2
Step-by-step explanation:
2n - 8 = -2 (-3n + 12) + 8
2n - 8 = -(-6n + 24) + 8
2n - 8 = 6n - 24 + 8
2n - 8 = 6n - 16
-4n = -8
Divide each side by 4
n = 2
This can be expressed as exponential growth of the form:
f=ir^t, f=final amount, i=initial amount, r=common ratio (rate), t=time
In this case we are given the point (2, 6500) and i=5000 so we can solve for the rate...
6500=5000r^2 divide both sides by 5000
1.3=r^2 take the square root of both sides and note that we know r>0
r=1.3^(1/2) so our equation becomes:
f=5000(1.3)^(1/2)^t and knowing that (a^b)^c=a^(b*c) we can say:
f=5000(1.3)^(t/2) so for t=18
f=5000(1.3)^9
f≈53022 (to nearest whole bacteria)
Answer: 75% of 6th Grade Students
Step-by-step explanation:
This sample makes the most sense because it is a majority of everyone, not just a majority of certain people. Also, Mountain School would get fewer complaints from other people if they went with a majority of 75%. Finally, running sports usually cost less then other sports.
