Answer:
See below
Step-by-step explanation:
<h3>Given</h3>
- Initial population at 8:00 AM
- 3000000
- Growth rate = 10% = 1.1 times per 20 min
<h3>Solution</h3>
<u>1. Table</u>
<em>Note. I am not sure what are the last 3 rows. Just added next 3 terms.</em>
- 8:00 ≡ G(0) ≡ 3000000 ≡ 3000000
- 8:20 ≡ G(1) ≡ 3000000 *1.1 ≡ 3300000
- 8:40 ≡ G(2) ≡ 3000000 *1.1^2 ≡ 3630000
- 9:00 ≡ G(3) ≡ 3000000 *1.1^3 ≡ 3993000
- 9:20 ≡ G(4) ≡ 3000000 *1.1^4 ≡ 4392300
<u>2. Population at 10:00</u>
- Time passed since 8:00 is 2 hours = 2*3*20 min = 6* 20 min
- Population = 3000000*1.1^6 = 5314683
<u>3. Function to reflect the population growth</u>
- G(x) = 3000000*1.1^x
- G(x) - is dependent variable, population of bacteria
- x - is independent variable, time increment of 20 min
<u>4. Population after 5 hours</u>
- 5 hours = 5*3*20 min = 15*20 min
- G(15) = 3000000*1.1^15 ≈ 12531745
First dstribute the -5
-8p-5+5p=0
Add like terms
-3p-5=0, add 5 on both sides
-3p=5, divide -3 on both sides
p=-5/3
Answer:
b = 141
Step-by-step explanation:
b − –573 = 714
Subtracting a negative is adding
b + 573 = 714
Subtract 573 from each side
b − 573+573 = 714-573
b =141
Find the rate of growth
224=222(1+r)^(2001-1992)
Solve for r
R=0.000997 without %
P=224(1.000997)^(2004-2001)
P=224×(1.000997)^(3)
P=224.67 million
