Answer:

f(x) = 2x³ - 12x² - 2x + 60

Step-by-step explanation:

Given that the zeros are x = - 2, x = 3, x = 5 , then the factors are

(x + 2), (x - 3), (x - 5)

The polynomial is then the product of the factors, that is

f(x) = a(x + 2)(x - 3)(x - 5) ← a is a multiplier

To find a substitute (6, 48) into the polynomial

48 = a(8)(3)(1) = 24a ( divide both sides by 24 )

a = 2 , thus

f(x) = 2(x + 2)(x - 3)(x - 5) ← expand the last 2 factors using FOIL

     = 2(x + 2)(x² - 8x + 15) ← distribute the parenthesis

     = 2(x³ - 8x² + 15x + 2x² - 16x + 30)

     = 2(x³ - 6x² - x + 30) ← distribute by 2

     = 2x³ - 12x² - 2x + 60

Using the factor theorem, it is found that the polynomial function is given by:

[tex]p(x) = 2(x^3 - 6x^2 - x + 30)[/tex]

-----------------------------

Factor theorem:

Given a polynomial f(x), this polynomial has roots [tex]x_{1}, x_{2}, x_{n}[/tex] such that it can be written as: [tex]a(x - x_{1})*(x - x_{2})*...*(x-x_n)[/tex], in which a is the leading coefficient.

-----------------------------

The polynomial is given by:

[tex]p(x) = a(x - x_1)(x - x_2)(x-x_3)[/tex]

[tex]p(x) = a(x - (-2))(x - 3)(x - 5)[/tex]

[tex]p(x) = a(x + 2)(x - 3)(x - 5)[/tex]

[tex]p(x) = a(x^2 - x - 6)(x - 5)[/tex]

[tex]p(x) = a(x^3 - 6x^2 - x + 30)[/tex]

-----------------------------

[tex]p(x) = a(x^3 - 6x^2 - x + 30)[/tex]

[tex]48 = a(6^3 - 6(6)^2 - (6) + 30)[/tex]

[tex]24a = 48[/tex]

[tex]a = \frac{48}{24}[/tex]

[tex]a = 2[/tex]

Thus, the polynomial is given by:

[tex]p(x) = 2(x^3 - 6x^2 - x + 30)[/tex]

Answer:

Joey sold 6 cars

Step-by-step explanation:

Joey earns $350 per week + $200 per car he sells

The number of cars that he sold last week is unknown, so represent it with a variable, x.

Write an equation

$350 + $200x = $1,550

Subtract $350 from both sides of this equation

$200x = $1200

Divide both sides of the equation by 200

x = 6

Joey sold 6 cars

Answer:

6.2 meters

Step-by-step explanation:

I got it right on a test.

So the right answer is 8 1/8 ft^2.

look at the attached picture

Hope it will help you..

Good luck on your assignment..

Answer:

8 1/8 ft^2

Step-by-step explanation:

The area of a rectangle is found by

A = l*w

A = 3 1/4 * 2 1/2

Change to improper fractions

3 1/4 = (4*3+1)/4 = 13/4

2 1/2 = (2*2+1)/2 = 5/2

A = 13/4 * 5/2 = 65/8

Changing back to a mixed number

8 goes into 65 8 times (8*8=64) with 1 left over

65/8 = 8 1/8 ft^2

Answer: A,B,D,E

Step-by-step explanation: All of them either have a base and height of 4, or if its E, it is 8 by2. The formula for solving a triangle is base x height divided by 2. In this case, the two sides have to equal 16, as the area is 16/2, or 8

the triangles that have an area of 8 square units in the picture are

A, B, D  and E

Given :

The graph of 4 triangles are given

We know that the area of the triangle formula is

[tex]\frac{1}{2} \cdot base \cdot height \\[/tex]

Lets find out the area of each triangle .

(A) base =4  and height =4

[tex]Area=\frac{1}{2}\cdot 4 \cdot 4=8 \; square \; units[/tex]

(B) base =4, height =4

[tex]Area=\frac{1}{2}\cdot 4 \cdot 4=8 \; square \; units[/tex]

(C) base = 3 and height =5

[tex]Area=\frac{1}{2}\cdot 5 \cdot 3=\frac{15}{2} \; square \; units[/tex]

(D) base =4  and height =4

[tex]Area=\frac{1}{2}\cdot 4 \cdot 4=8 \; square \; units[/tex]

(E) base = 8 and height =2

[tex]Area=\frac{1}{2}\cdot 8 \cdot 2=8 \; square \; units[/tex]

the triangles that have an area of 8 square units in the picture are

A, B, D  and E

Answer:

[tex]f(x)=89x+1800[/tex]

Step-by-step explanation:

$1800 is spent on a washing machine. This number never changes, so we just need to add that to our annual total

$89 is spent every year. This means that this number needs to be with our variable, x, as it is dependent on the number of years that occur. When we put these two things together, we get the following equation:

Step-by-step explanation:

Answer:

280

Step-by-step explanation:

each of those squares are 100 and each bar is 10

add up the squares and you have 200

add up the bars and you have 80

add 200 and 80 and you have your answer. 280

Answer:

D

Step-by-step explanation:

Well, the bars, if you count them are ten for each column.

There are 8 bars on the right, so that is 280 - 80 = 200

There are two squares that are ten by ten, so that is 200 - 100 * 2 = 0

Answer:

-2.17 and -7.83

Step-by-step explanation:

[tex]4(x+5)^2=32[/tex]

Divide both sides by 4:

[tex](x+5)^2=8[/tex]

Take the square root of both sides:

[tex]x+5=\pm 2\sqrt{2}[/tex]

Subtract 5 from both sides:

[tex]x=-5\pm 2\sqrt{2}\approx -2.17, -7.83[/tex]

Hope this helps!

Answer:

-92(I think I am wrong, now that I think of it.)

Step-by-step explanation:

4(x+5)^2= 32= 4x+20^2= 32= 4x+400= 32= 4x= -368= -92

20^2= 400

32-400= -368

Answer:

$64

Step-by-step explanation:

Since the store buys the racket for $40 then marks it up, the store is selling it for 160% of the wholesale price. X is the price we are looking for - the price after it was marked up.

40 / x = 100/160

(40/x) * x = (100/160) * x      

40 = 0.625 * x  

40/0.625 = x

64 = x

x = 64

Answer:

Θ = 0, π, [tex]\frac{7\pi }{6}[/tex], [tex]\frac{11\pi }{6}[/tex]

Step-by-step explanation:

Using the identity

cos2Θ = 1 - 2sin²Θ, then

sinΘ + 1 = 1 - 2sin²Θ ( subtract 1 - 2sin²Θ from both sides )

2sin²Θ + sinΘ = 0 ← factor out sinΘ from each term

sinΘ(2sinΘ + 1) = 0

Equate each factor to zero and solve for Θ

sinΘ = 0, hence

Θ = [tex]sin^{-1}[/tex] (0) = 0, π, 2π

2sinΘ + 1 = 0 → sinΘ = - [tex]\frac{1}{2}[/tex] , thus

Θ = [tex]sin^{-1}[/tex] ( - [tex]\frac{1}{2}[/tex] ) = - [tex]\frac{\pi }{6}[/tex]

Since sinΘ < 0 then Θ is in third/ fourth quadrants, thus

Θ = π + [tex]\frac{\pi }{6}[/tex] = [tex]\frac{7\pi }{6}[/tex] or Θ = 2π - [tex]\frac{\pi }{6}[/tex] = [tex]\frac{11\pi }{6}[/tex]

Solution is

Θ = 0, π, [tex]\frac{7\pi }{6}[/tex], [tex]\frac{11\pi }{6}[/tex] for 0 ≤ Θ < 2π
