Question

The size of a slow-growing bacteria strain increases continuously over time. This equation describes the predicted size of the bacteria strain, in square millimeters, after t minutes: y = 112(1.58)t. According to the equation, what will the approximate size of the bacteria strain be after 5 minutes?

Answer 1

Step-by-step explanation:

To find the size of bacteria in five minutes, substitute 5 for t in the equation and simplify:

y = 112(1.58)5

= 112 ∙ 9.85

= 1,103.2.

Round the answer to the closest integer to get 1,103.

Step-by-step explanation:

Answer 2

1102.8 mm^2

Step-by-step explanation:

We presume your equation is intended to be ...

y = 112(1.58)^t

Since t is in minutes, fill in the given value and do the arithmetic:

y = 112(1.58)^5 = 112(9.84658) ≈ 1102.8

The approximate size of the bacteria strain will be 1102.8 mm^2 after 5 minutes.
