Answer:
P(x) = - 7x² + 12
Step-by-step explanation:
Given zeros x = 2, x = - 2, x = , x = -
Then the factors are (x - 2), (x + 2), (x - ), (x +
)
and the polynomial is the product of the factors, that is
P(x) = (x - 2)(x + 2)(x - )(x +
) ← expand in pairs using FOIL
= (x² - 4)(x² - 3) ← distribute
= - 3x² - 4x² + 12 ← collect like terms
= - 7x² + 12
Answer:
Principle should be $2,667
Step-by-step explanation:
We need $3000 for a vacation to Europe in 3 years.
Using amount formula,
Where, P is principle (P=?)
A is amount (A=3000)
r is rate of interest (r=0.04)
t is time (t=3)
Substitute the values into formula and solve for P
Hence, Principle should be $2,667
The correct option will be: A. 67%
<em><u>Explanation</u></em>
Given equation is: , where
is the length of the film in minutes and
is the percentage of people finish watching the film.
Here, the length of the documentary is given as 95 minutes. So, we will <u>plug into the above equation</u> and get....
<em>(Rounded to the nearest percent)</em>
So, the percentage of people in an audience who will finish watching a documentary that is 95 minutes long will be 67%
