When a bactericide is added to a nutrient broth in which bacteria are​ growing, the bacteria population continues to grow for a​
baherus [9]

Answer:

a)  1296 bacteria per hour

b) 0 bacteria per hour

c) -1296 bacteria per hour

Step-by-step explanation:

We are given the following information in the question:

The size of the population at time t​ is given by:

b(t) = 9^6 + 6^4t-6^3t^2

We differentiate the given function.

Thus, the growth rate is given by:

\displaystyle\frac{db(t)}{dt} = \frac{d}{dt}(9^6 + 6^4t-6^3t^2)\\\\= 6^4-2(6^3)t

a) Growth rates at t = 0 hours

\displaystyle\frac{db(t)}{dt} \bigg|_{t=0}= 6^4-2(6^3)(0) = 1296\text{ bacteria per hour}

b) Growth rates at t = 3 hours

\displaystyle\frac{db(t)}{dt} \bigg|_{t=3}= 6^4-2(6^3)(3) = 0\text{ bacteria per hour}

c) Growth rates at t = 6 hours

\displaystyle\frac{db(t)}{dt} \bigg|_{t=6}= 6^4-2(6^3)(6) = -1296\text{ bacteria per hour}

The normal temperature range for Yuma, AZ on January 11 is at least 48 degrees but no higher than 64 degrees Fahrenheit. Which i
WITCHER [35]

Answer: Our required interval for temperature is 48\leq x\leq 64

Step-by-step explanation:

Since we have given that

The normal temperature range for Yuma, on Janurary is atleast = 48 degrees

and the highest temperature on that day is no higher than 64 degrees.

Let the temperature in Yuma be 'x'.

So, we know that for atleast means it can 48 degrees or more, and no higher than means it should be equa to or less than 64 degrees.

Mathematically, it is expressed as

48\leq x\leq 64

Hence, our required interval for temperature is 48\leq x\leq 64
