According to the Fundamental Theorem of Algebra, the number of roots of a polynomial is equal to the degree of the polynomial. The degree of the polynomial is the highest exponent of a term in the polynomial.
Looking at the function, the term with the highest exponent is 8x7. The exponent is 7; therefore, the function has 7 roots.

According to the Fundamental Theorem of Algebra, the roots exist for the polynomial function f\left( x \right) = 8{x^7} - {x^5} + {x^3} + 6 x is \boxed7.

Further explanation:

The Fundamental Theorem of Algebra states that the polynomial has n roots if the degree of the polynomial is n.

f\left( x \right) = a{x^n} + b{x^{n - 1}} +\ldots  + cx + d

The polynomial function has n roots or zeroes.

Degree is highest power of the polynomial function.

Given:

The polynomial function is f\left( x \right) = 8{x^7} - {x^5} + {x^3} + 6.

Explanation:

The polynomial function f\left( x \right) = 8{x^7} - {x^5} + {x^3} + 6 has seven zeroes as the degree of the polynomial is 7.

According to the Fundamental Theorem of Algebra, the roots exist for the polynomial function f\left( x \right) = 8{x^7} - {x^5} + {x^3} + 6 is \boxed7.

Which expression is equal to x + (y + z)?
arsen [322]
X+(y+z) is equal to saying (x+y)+z

This is called the cumulative property when order doesn’t matter or doesn’t change the equation. As in 1+2 is the same as 2+1. No matter which way we get the same answer. This only works with multiplication and addition though. Hope this helps. Any questions please just ask!! Thank you so much!!

Answer:

The following is an income statement using the Contribution format.

...........................Income Statement for Rivieremia Corp................................

Sales ........................................................................$1,500,000

Less Variable Costs................................................<u>($1,200,000)</u>

Contribution Margin..............................................$300,000

Less Fixed Costs....................................................<u>($200,000)</u>

Operating Income .................................................$100,000

Less Tax...................................................................<u>.($10,000)</u>

Net Income...............................................................$90,000

Tax = 10% * 100,000 = $10,000

Proving breakeven is $1,000,000.

The breakeven point for a company can be calculated by dividing the Fixed cost by the contribution margin ratio.

Contribution margin ratio = Contribution margin / Sales

= 300,000/1,500,000

= 20%

= Fixed Cost/ Contribution Margin ratio

= 200,000/20%

= $1,000,000

Degree of Operating Leverage = Contribution Margin/ Operating Income

= 300,000/100,000

= 3

The scale of a model train is 1 inch to 13.5 ft. One of the cars of the model train is 5inches long. What is the length in feet
aleksklad [387]

Answer:

The length of the actual train's car is <u>67.5 feet.</u>

Step-by-step explanation:

Given:

The scale of a model train is 1 inch to 13.5 ft.

Now, to get the length of the actual car of the train.

Let the length of actual train's car be x.

And, the length of the car of model train = 5\ inches\ long.

<em>According to the scale of the model train, 1 inch is equivalent to 13.5 ft. </em>

<em>Thus, 5 inches is equivalent to </em>x.<em />

Now, to get the length of actual train's car using cross multiplication method:

\frac{1}{13.5} =\frac{5}{x}

By cross multiplying we get:

x=67.5\ feet.

Therefore, the length of the actual train's car is 67.5 feet.
