59
Step-by-step explanation:
To find f(3), substitute 3 for x:

Answer:

Step-by-step explanation:
A quadratic needs 2 solutions, but since you only have 1, I am to assume that x = -8 twice (or multiplicity of 2). If x = -8, then in factor form, it's (x + 8). Muliplying that by itself twice:
(x + 8)(x + 8):

Simplifying gives you:

Answer:
sample size at the beginning was 40 bacteria.
Step-by-step explanation:
Given that a sample of bacteria experienced 5% daily growth compounded continuously for 14 days
Let C be the initial amount of bacteria.
C grows continuously compounding at the rate of 5%
The equation representing the number of bacteria at time t days would be

Now we have t = 14 days and P = 80.
Substitute to get

Approximately 40 bacteria were present at the beginning.
