Answer:1) bacteria size = b(initial) * e^(r * t)
initial size = 300
final size = 1600.
Substituting the values into the main equation:
1600 = 300 * e^(r * 35 - 20)
solving for 'r'.
1600 = 300 * e^(r * 15)
1600/300 = e^(r * 15)
taking natural log on both sides to eliminate the power
ln(16/3) = ln[e^(r * 15)]
ln(16/3) = r * 15
r = ln(16/3) / 15
= 0.11159843
= 11.16%
To find the initial bacteria size,
Given: t = 20
300 = b * e^(0.1116 * 20)
Solving for b:
300 = b * e^2.232
b = 300/e^2.232
b = 32

Answer:
He should have drunk 28 gallons in 7 days
Step-by-step explanation:
This is pretty simple, so let's assume he drank 4 galloiljs of water a day. 4 gallons a day x 7 days
4*7
that is 28

The answer to this problem is 5/12.
Answer:
Step-by-step explanation:
g(x) = 3(x + 8).....find g(12).....what ur basically doing is subbing in 12 for x
g(12) = 3(12 + 8)
g(12) = 3(20)
g(12) = 60 <===
