Homework Help: Math

Posted by Walt on Tuesday, February 14, 2012 at 5:24pm.

Can you check my work Please?

Let N(t) be the number of bacteria after t days. Then N(t) = Pa^t for some constants P and a. Measurements indicate that N(4) = 5600 and N(8) = 362, 000

1. Write down the formula for N(t) using the rounded values of a and P. (But remember to use the more precise stored values when you use the formula!)
2. Evaluate N(7), N(9), and N(11). (Give answers to the nearest bacterium.)

1. My formula: 86.6(2.84)^t (these are rounded values)

2. (Using non Rounded Values I got the following)
N(7) = 17667 N(9) = 1026452 N(11) = 8252755
