Homework Help: Math

Posted by Walt on Monday, February 13, 2012 at 7:38pm.

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.

b. Write down two equations for P and a, one when t = 4 and the other when t = 8.
c. Use these two equations to compute a and P. Round your values to three significant
digits, but be sure to store the more precise values for further calculations


My equations:
Pa^4 = 5600
Pa^8 = 362000

My rounded values:
P=86.1
a=2.84

Thank You For Checking
