P = potato C = corn
3P + 4C = $40
5P + 2C = $34
Multiply -2 to the 2nd equation to get
-10P - 4C = -68
Add it to the 1st equation
3P + 4C = 40
-10P - 4C = -68
-----------------------
-7P = -28
Solve for P
P = $4
Substitute 4 into P(potato) to find what C(corn) is
Answer:
I think the answer is a 148 cm squared
Step-by-step explanation:
Using an exponential function, it is found that the population of bacteria in the culture after 13 hours is of 1,491,747.
An <em>exponential function</em>, with a <u>doubling time of d, after t hours</u>, is given by:
- In which A(0) is the initial amount.
In this problem:
- The doubling time is of 3 hours, hence .
- The initial population is of 74000 bacteria, hence .
Then:
After 13 hours:
The population of bacteria in the culture after 13 hours is of 1,491,747.
