Hello! Let's look at the two parts of this question.

Complete the table:

In this case, you just substitute the value of "hour" into the equation, for the value of t. For example:

P(0) = 120 (2)^{0}

P(0) = 120 (1)

P(0) = 120

Therefore, the number of bacteria for hour 0 is 120.

You can do this for the next ones. Hour 1 = 240, hour 2 = 480, and so on. (In this case, you can keep multiplying by 2)

Estimate when there will be more than 100,000 bacteria:

Set the final value of P(t) = 100,000, then solve.

100,000 = 120 (2)^{t}

833.33 = (2)^{t}

t = log_{2}833.33

t = 9.702744108

So your answer would be around 9.7 years, or, around 10 years.

Hope this helps!

N(2x+y) = x +1 

Differentiate both sides, using the Chain Rule on the left side. 
(1 / (2x + y)) * d(2x + y)/dx = 1 
(1 / (2x + y)) * (2 + dy/dx) = 1

Need help on question please!!
Zepler [3.9K]

you'd use the pythagorean theorem.

a^2+b^2=c^2

a is the first leg, b is the second leg, and c is the third leg.

10^2+13^2=c^2

100+169=c^2

269=c^2

take the square root of both sides

16.4=c

16.4cm is your answer!

IgorLugansk [536]

Answer:

\sqrt{21}\ km or  4.58\ km  

Step-by-step explanation:

we know that

Applying Pythagoras' Theorem, calculate how many kilometers eastward Santos walked

so

Let

x----> quantity of kilometers eastward that Santos walked

x^{2}=5^{2}-2^{2}

x^{2}=21

x=\sqrt{21}\ km ----> exact value

\sqrt{21}=4.58\ km  -----> approximate value
