Answer:

3 $x^{4}$ - 10x³ - x² - 11x + 6

Step-by-step explanation:

Each term on the upper row is multiplied by each term on the lower row.

This can be expressed as

3x²(x² - 5x + 2) + 2x(x² - 5x + 2) + 3(x² - 5x + 2) ← distribute parenthesis

= 3 $x^{4}$ - 15x³ + 6x² + 2x³ - 10x² + 4x + 3x² - 15x + 6 ← collect like terms

= 3 $x^{4}$ - 10x³ - x² - 11x + 6

G(x) = -2x^3 – 15x^2 + 36x

shusha [124]

Consider the function $G(x) = -2x^3 - 15x^2 + 36x.$ First, factor it:

$G(x) = -2x^3 - 15x^2 + 36x=-x(2x^2+15x-36)=\\ \\=-x\cdot 2\cdot \left(x-\dfrac{-15-\sqrt{513}}{4}\right)\cdot \left(x-\dfrac{-15+\sqrt{513}}{4}\right).$

The x-intercepts are at points $\left(\dfrac{-15-\sqrt{513} }{4},0\right),\ (0,0),\ \left(\dfrac{-15+\sqrt{513} }{4},0\right).$

1. From the attached graph you can see that

function is positive for $x\in \left(-\infrty, \dfrac{-15-\sqrt{513} }{4}\right)\cup \left(0,\dfrac{-15+\sqrt{513} }{4}\right);$
function is negative for $x\in \left(\dfrac{-15-\sqrt{513} }{4},0\right)\cup \left(\dfrac{-15+\sqrt{513} }{4},\infty\right).$

2. Since

$G(-x) = -2(-x)^3 - 15(-x)^2 + 36(-x)=2x^3-15x^2-36x\neq G(x)\ \text{and }\neq -G(x)$ the function is neither even nor odd.

3. The domain is $x\in (-\infty,\infty),$ the range is $y\in (-\infty,\infty).$

Ten minus One-third of a number is 4

zloy xaker [14]

Ok, so you automatically know that you are subtracting 6 from 10 to get 4. So, in order to figure out how it is 1/3 of that number, it is going to be multiplied by 3, getting 18. So, the number would be 18.

W = p ( y -z ) Please solve this for z.

11111nata11111 [884]

w = p(y - z)

divide p on both sides

$\frac{w}{p} = y - z$

Subtract y on both sides

$\frac{w}{p} - y = -z$

Divide -1 on both sides

$-\frac{w}{p} +y=z$

What is the value of h in the equation 8h = 60

irga5000 [103]

Answer:

h= 7.5

Step-by-step explanation:

8h=60

One solution was found :

h = 15/2 = 7.500

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

8*h-(60)=0

Step by step solution :

Step 1 :

Pulling out like terms :

1.1 Pull out like factors :

8h - 60 = 4 • (2h - 15)

Equation at the end of step 1 :

Step 2 :

Equations which are never true :

2.1 Solve : 4 = 0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

2.2 Solve : 2h-15 = 0

Add 15 to both sides of the equation :

2h = 15

Divide both sides of the equation by 2:

h = 15/2 = 7.500

One solution was found :

h = 15/2 = 7.500
