Question

The growth of a new strain of bacteria is represented by 7=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 6
A.833
B.117
C.704
D.647

Answer 1

Y (x)=79.31(1.48)^x
Y (6)=79.31×(1.48)^(6)
Y (6)=833

Answer 2

Answer:

A. 833

Step-by-step explanation:

Given:

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.

We need to find the number of bacteria on day 6.

So, here x = 6, we need to plug in x = 6 in the given function and find the answer.

[tex]y = 79.31(1.48)^6[tex]

Simplify the above expression, we get

y = 833.49

The bacteria cannot be in decimal form, let's round off the answer to nearest whole number.

y = 833

Therefore, answer is A. 833
