Answer:

132v^2, -v
24v^6, -2v^3
18v^12, 7v^6
-56v^14, -15v^7
3v^20, -2v^10

Step-by-step explanation:

The product is the product of the numbers, multiplied by the product of the variable factors. The variable is the same in every term, so the product of the variable factors will have an exponent that is the sum of the exponents.

The difference will have a coefficient that is the difference of the coefficients.

(11v)(12v) = 132v^2 . . . . 11v -12v = -v

(4v^3)(6v^3) = 24v^6 . . . . 4v^3 -6v^3 = -2v^3

(9v^6)(2v^6) = 18v^12 . . . . 9v^6 -2v^6 = 7v^6

(-8v^7)(7v^7) = -56v^14 . . . . -8v^7 -7v^7 = -15v^7

(-3v^10)(-v^10) = 3v^20 . . . . -3v^10 -(-v^10) = -2v^10

Predict how many times you will roll a number less than 3 if you roll a standard number

Korvikt [17]

Answer:

about 117 times

Step-by-step explanation:

No. of possible outcomes of a cube: 6

2 out the 6 possible outcomes are less than 3,

and therefore, No. of favorable outcome: 2

P(less than 3)= No. of favorable outcome / No. of possible outcomes

=2/6 => 1/3

if you roll a standard number cube 350 times then,

Prediction= number of rolls x (P(less than 3))

=350 x 1/3

≈117 times.

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

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

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

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

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

PLEASE HELP WILL GIVE BRAINLIEST!!!The table below represents the closing prices of stock ABC for the last five days

irakobra [83]

Answer:

A. $y=-8.583x+475.215$

Step-by-step explanation:

We are given,

The table representing the closing prices of stock for the last five days is,

Day Value

1 472.08

2 454.26

3 444.95

4 439.49

5 436.55

Using the linear regression calculator, we have that,

<h3>The linear equation that best fits the data is $y=-8.583x+475.215$ </h3>

Thus, option A is correct.
