Apopulation of bacteria is introduced into a culture. the number of bacteria p can be modeled by p(t) = 800 1 + 9t 90 + t2 , where t is the time in hours since the bacteria was introduced. find the rate of change of the population (in bacteria per hour) after 6 hours. (round your answer to one decimal place.)

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

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

so the rate of change after 6 hours is 12.9

where

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

2/3x + 7 = 29

step-by-step explanation:

two thirds = 2/3

plus a number = x

at least 29 = 29

there for you should get 2/3x + 7 = 29

where is the graph, sweetheart?
