$1\ \text{billion}=1\times 10^9$

$1\ \text{million}=1\times 10^6$

Total amount of water left is

$8\ \text{billion ounces}\\ =8\times 10^9\ \text{ounces}\\ =(8\times 10^3)\times 10^6\ \text{ounces}\\ =8000\ \text{million ounces}$

Yearly consumption of water $13\ \text{million ounces}$

t = Years since 2018

The required function is in million ounces which is $V(t)=8000-13t$

The first term of an arithmetic sequence is-3 and the 15 term is 53. What is the common difference of the sequence?

Annette [7]

$a_2=a_1+d$
$a_3=a_2+d=a_1+2d$
$a_4=a_3+d=a_1+3d$
...
$a_{15}=a_1+14d$

Since $a_1=-3$ and $a_{15}=53$ , the common difference $d$ is

$53=-3+14d\implies d=4$

<h3>What is exponential Growth ?</h3>

Exponential growth is when the quantity increases according to the function

$P_t = P_0 e^{ kt}$

It is given in the question that

Initial number of Bacteria is 50

After 3 hours the bacteria has increased to 80

The bacterial growth is an exponential growth

$P_t = P_0 e^{ kt}$

$80 = 50 e^{ k * 3}$

Applying log on both sides

1.6 = 3*k

k = 1.6/3

k = 0.533

if this rate of growth continues, how much more time will it take for the number of bacteria to reach 1119

$1119 = 50e^{0.533* t}\\\\3.18 = 0.533 *t\\\\5.83 = t$

Therefore it will take 5.83 hours for the bacteria to reach 1119.
