In a laboratory experiment, the population of bacteria in a petri dish started off at 160 and is growing exponentially at 6% per

hour. Write a function to represent the population of bacteria after t hours, where the rate of change per minute can be found from a constant in the function. Round all coefficients in the function to four decimal places. Also, determine the percentage rate of change per minute, to the nearest hundredth of a percent.

The exponential function is given by y = 160(1.06)ˣ

<h3>Exponential function</h3>

An exponential function is in the form:

y = abˣ

where a is the initial value of y, b is the multiplier, y, x are variables.

Let y represent the amount of bacteria after x hours.

Given an initial 160 bacteria, hence a = 160.

Also b = 100% + 6% = 106% = 1.06

The exponential function is given by y = 160(1.06)ˣ

If the side length is greater than 11.11 cm then it will not overflow.

Otherwise, it will overflow.

If Joe tips the bucket of water in a cuboid container and the water is not overflowing then the cuboid container must be of volume greater than 1370 cm³.

We find the cube root of 1370 cm³.

\sqrt[3]{1370} \approx11.11

Then the cuboid container should have a side of length greater than 11.11 cm.

Here the statement  "If I tip my bucket of water in the cuboid container, it will never overflow" is correct or wrong based on the information that the container has a side length lesser or greater than 11.11 cm.

If the side length is greater than 11.11 cm then it will not overflow.

Otherwise, it will overflow.

An investor has an account with stock from two different companies. Last year, his
Lesechka [4]
22.7%

Given that last year stock for company A was $7200
The stock for company B last year was worth $3510
Stock in company A decreased by 24%
This means the new value of stock for company A became;
(100-24)/100 *$7200
76/100*$7200
0.76*7200 =$5472
Stock in company B decreased by 20%
This means the new value of stock for company B became;
(100-20)/100 *$3510
80/100*$3510
0.8*$3510
$2808
Original investors stock value was = $7200+$3510 =$10710
New investors stock value is = $5472+$2808=$8280
Decrease in value of stock = $10710-$8280 =$2430
percentage decrease in stock value = decrease in stock/original value of stock *100%
=2430/10710 *100 =22.689
=22.7%

stich3 [128]
Quantity of farmland owned by Pam = 7.5 square miles.
The other important information given in the question is the equation relating square miles and acres. Using that information, the answer to the question can be easily reached.
a = 640s
   = 640 * 7.5 acres
   = 4800 acres.
From the above deduction, we can conclude that the correct option among all the options that are given in the question is the third option or option "C".
