An advertising company designs a campaign to introduce a new product to a metropolitan area of population 3 Million people. Let
Advocard [28]

Answer:

P(t)=3,000,000-3,000,000e^{0.0138t}

Step-by-step explanation:

Since P(t) increases at a rate proportional to the number of people still unaware of the product, we have

P'(t)=K(3,000,000-P(t))

Since no one was aware of the product at the beginning of the campaign and 50% of the people were aware of the product after 50 days of advertising

<em>P(0) = 0 and P(50) = 1,500,000 </em>

We have and ordinary differential equation of first order that we can write

P'(t)+KP(t)= 3,000,000K

The <em>integrating factor </em>is

e^{Kt}

Multiplying both sides of the equation by the integrating factor

e^{Kt}P'(t)+e^{Kt}KP(t)= e^{Kt}3,000,000*K

Hence

(e^{Kt}P(t))'=3,000,000Ke^{Kt}

Integrating both sides

e^{Kt}P(t)=3,000,000K \int e^{Kt}dt +C

e^{Kt}P(t)=3,000,000K(\frac{e^{Kt}}{K})+C

P(t)=3,000,000+Ce^{-Kt}

But P(0) = 0, so C = -3,000,000

and P(50) = 1,500,000

so

e^{-50K}=\frac{1}{2}\Rightarrow K=-\frac{log(0.5)}{50}=0.0138

And the equation that models the number of people (in millions) who become aware of the product by time t is

P(t)=3,000,000-3,000,000e^{0.0138t}

Which value for x makes the open sentence true? 5⋅x+1=1+x2 5 4 3 2
Aleksandr-060686 [28]

Hey!

Let's solve this together.

5x+1 = 1+x2

Possible Answers: {5,4,3,2}

Lets start with 5.

5(5)+1 = 1+2(5)***

25+1 = 1+10

26 ≠ 11

So, 5 is NOT the answer.

Now, 4.

5(4)+1 = 1+(4)2

20+1 = 1+8

21 ≠ 9

So, 4 is NOT the answer.

Now, 3.

5(3)+1 = 1+(3)2

15+1 = 1+6

16 ≠ 7

So, 3 is NOT the answer.

Lastly, 2.

5(2)+1 = 1+(2)2

10+1 = 1+4

11 ≠ 5

So, 2 is NOT an answer.

So, the answer is: None of the above. None of them can be answers because none of them make the statement true.

***(In algebra, we start using parenthesis instead of the dot for multiplication when using numbers.)

Hope this helps!
