$\: \: \: \:$

$= {a}^{2} \: {b}^{2} - {b}^{2} \: {c}^{2}$

Step-by-step explanation:

$(ab + bc)(ab - bc)$

use ( a + b ) ( a + b ) = a² - b² to simply the product

$(ab {)}^{2} - (bc {)}^{2}$

to raise a product to a power ,raise each factor to that power

$= {a}^{2} {b}^{2} - {b}^{2} {c}^{2}$

The equation c=0.09s gives the amount c (in dollars) of commission a salesperson receives for making a sale of s dollars.

hram777 [196]

Answer:

The independent variable is s

The dependent variable is c

Step-by-step explanation:

Identify the independent and dependent variables:

The equation c = 0.09s gives the amount c (in dollars) of commission a salesperson receives for making a sale of s dollars.

c = 0.09s

Where

c = commission the salesperson makes

s = amount of sales

The variables in the equation are c and s

The independent variable is s

The dependent variable is c because it's value is determined by the amount of sales of the salesperson

Suppose the graph of a cubic polynomial function has the same zeroes and passes through the coordinate (0, -5). Write the equati

amid [387]

In this we know all three zeros and one point from which the graph pass.
So we will let specific cubic polynomial function of the form
$f(x) = a(x - x_1)(x-x_2)(x-x_3)$

As we know zeros are that point where we will get value of function equal to zero. So it is basically in form $(x_n , 0)$

SO in given question zeros are (2 , 0) , (3, 0) and (5,0)
So we can say $x_1 = 2 , x_2 = 3 , x_3 = 5$

So required equation is
$f(x) = a (x-2)(x-3)(x-5)$
              $= a[(x^2 - 2x - 3x + 6)(x-5)]$
              $= a[(x^2 - 5x+6)(x-5)]$
              $= a(x^3 - 5x^2 + 6x- 5x^2 + 25x - 30)$
              $= a(x^3 - 10x^2+31x-30)$
Now we have one point (0 , -5) from which graph passes.
So we say at x = 0 , f(x) = -5
$-5= a (0-0+0 - 30)$
$-5 = -30a$
$a = \frac{-5}{-30} = \frac{1}{6}$
So required equation of cubic polynomial is
$f(x) = \frac{1}{6}(x^3 -10x^2+31x-30)$

For finding y - intercept we simply plugin x = 0 in given equation.
As we know at x = 0 , value of function is -5.
So y - intercept is -5.
