A population of bacteria is introduced into a culture. The number of bacteria P can be modeled by P(t) = 800 1 + 9t 90 + t2 , wh
love history [14]

Answer: Hello mate!

you know that the equation is (or at least i think this is):

p(t) = 800 + 9t/90 + t^2

You want to know the "rate of change" after 6 hours.

We know that the rate of change is the derivative of P(t) with respect to t; this is

\frac{dP(t)}{dt} = 9/90 + 2t

now we want the rate of change when t = 6, then we replace t by 6 in the derivate equation:

p(6)' = 0.9 + 2*6 = 12.9

so the rate of change after 6 hours is 12.9

where P'(t) = \frac{dP(t)}{dt}

If the equation is wrong ( because you write P(t) = 800 1 + 9t 90 + t2, and i don really know how to iterprete it) tellme and we can do the derivate again :D

12.6% of<br>RI 149 390bn​
galina1969 [7]

Answer: RI 18,823.14

Step-by-step explanation:

I guess that we want to find the 12.6% of Rl 149,390

First, we assume that Rl 149,390 is the 100%

Then we can write an equation like:

Rl 149,390 = 100%

Then if the amount X is the 12.6%, we also have the equation:

X = 12.6%

Then we have the two equations:

X = 12.6%

Rl 149,390 = 100%

If we take the quotient between these two equations we get:

(X/Rl 149,390) = (12.6%/100%)

Solving this for X we get:

X =  (12.6%/100%)*(Rl 149,390) = RI 18,823.14
