The growth of a new strain of bacteria is represented by y = 79.31(1.48)x, where x represents the number of days and y represents the number of bacteria. which is the best prediction for the number of bacteria on day 7?
a. 821 bacteria
b. 1234 bacteria
c. 1819 bacteria
d. 117 bacteria

821 bacteria

Step-by-step explanation:

You have that the growth of bacteria is represented by:

y = 79.31(1.48)x

N° Bacteria=79.31(1.48)(N° Days)

If you know that N° Days is 7, you need to replace x=7 in the Equation given.

Then:

N° Bacteria=79.31(1.48)(N° Days)

N° Bacteria=79.31(1.48)(7)

N° Bacteria=821,65

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
