Write the simplest polynomial function for each set of zeros<br><br> Zeros = -2, 5, -1

deff fn [24]

Answer:

The polynomial is ;

x^3 -2x^2 -13x - 10

Step-by-step explanation:

Given the zeros, we set them to equal zero so as to get the linear factors

Mathematically, that will be as follows;

x = -2

x + 2

x = 5

x-5

x = -1

x + 1

So we have the polynomial as;

(x + 1)(x + 2)(x-5)

= (x -5)(x^2 + 3x + 2)

= x^3+ 3x^2 + 2x -5x^2 -15x - 10

= x^3 -2x^2 -13x - 10

A collector has 120 movie posters and 100 band posters. She wants

Juliette [100K]

Answer:

She should sell 20 band posters from total 80 to keep the maintain the same ratio.

Step-by-step explanation:

The total number of movie posters collector has = 120

The total number of band posters collector has = 80

The current ratio of movie poster : band poster = 120 : 100

or, reducing the ratio further, we get

ratio of movie poster : band poster = 6 : 5 ...... (1)

Now, the number of posters she wants to sell = 24

So, the remaining movie poster left = 120 - 24 = 96

Let us assume she sells m band posters to keep the ratio equal.

So, the number of band posters she is left with = 100 - m

⇒The ratio of movie poster left : band poster left = 96 : 100 - m .. (2)

Now here as the ratio remains same after selling m band posters, so

$\frac{6}{5} = \frac{96}{100 - m} \\\implies 100 - m = 96 \times\frac{5}{6} = 80\\or, 100 - 80 = m\\\implies m= 20$

or, m = 20

Hence, she should sell 20 band posters from total 80 to keep the maintain the same ratio.
