The description for a certain brand of house paint claims a coverage of 460 ft2/gal. (a) express this quantity in square meters
Angelina_Jolie [31]

Given 460 ft^2/gal

a) convert it into m^2/l

=> It means ft^2 -> m^2 and gal -> l

1 ft = 0.3048 m

1 ft^2 = 0.092903 m^2

1 gal = 3.78541 l

460ft^2= [tex]460\frac{ft^2}{gal} = \frac{42.7354m^2}{3.78541l} = 11.2895m^2/l m^2[/tex].

b.  11.2895\frac{m^{2} }{l} *1000\frac{l}{m^3} =11289.5 m^{-1}

c.Given=  460\frac{ft^2}{gal}

To find inverse, divide it by 1.

Inverse- \frac{1}{460} \frac{gal}{ft^2}

Write the cubic polynomial function f(x)in expanded form with zeros −6,−5,and −1, given that f(0)=60
RSB [31]

Answer:

f(x)=2x^{3}+24x^{2}+82x+60

Step-by-step explanation:

we know that

The roots of the polynomial are the values of x when the value of the polynomial f(x) is equal to zero

The roots of the polynomial function are

x=-6 -----> (x+6)=0

x=-5 -----> (x+5)=0

x=-1 -----> (x+1)=0

The equation of the cubic polynomial is

f(x)=a(x+6)(x+5)(x+1)

where

a is the leading coefficient

Remember that

f(0)=60

That means ------> For x=0 the value of f(x) is equal to 60

substitute the value of x and the value of y in the function and solve for a

60=a(0+6)(0+5)(0+1)

60=a(6)(5)(1)

60=30a

a=2

so

f(x)=2(x+6)(x+5)(x+1)

Applying the distributive property

Convert to expanded form                  

f(x)=2(x+6)(x+5)(x+1)\\\\f(x)=2(x+6)(x^{2}+x+5x+5)\\\\f(x)=2(x+6)(x^{2}+6x+5)\\\\f(x)=2(x^{3}+6x^{2}+5x+6x^{2}+36x+30)\\\\f(x)=2x^{3}+24x^{2}+82x+60
