What is the value of the coefficient 2x^3+18x^2-18x-162=2(x+k)(x-k)(x+9)

Answers

Answer 1

Answer: The polynomial
$2x^3+18x^2-18x-162=(2x^3+18x^2)-(18x+162)=$
$=2x^2(x+9)-18(x+9)=2(x+9)(x^2-9)=2(x+9)(x+3)(x-3)$ .
Then k=3.

Two fractions have the same denominator.which is the greater fraction with the greater numerator or the lesser numerator

Answers

The answer is-The fraction with greater numerator.

Let's understand this by an example.
Take denominator as 4.
And two numerators as 2 and 3 respectively.

Now, the numbers are 2/4 and 3/4
2/4 = 0.5
3/4 = 0.75

Which one is greater ?3/4
Therefore, 3/4 > 2/4

So, the fraction with greater numerator is greater

If f(x)=2x^2−3x+1 and g(x)=x+5, what is f(g(x))?

Answers

If $f(x)=2x^(2)-3x+1,$ then

$f(g(x))=2[g(x)]^(2)-3g(x)+1\n \n f(g(x))=2(x+5)^(2)-3(x+5)+1\n \n f(g(x))=2(x^(2)+10x+25)-3(x+5)+1\n \n f(g(x))=2x^(2)+20x+50-3x-15+1\n \n f(g(x))=2x^(2)+20x-3x+50-15+1\n \n \boxed{\begin{array}{c}f(g(x))=2x^(2)+17x+36 \end{array}}$

Positive fractions less than 1, with an interval of 1/8 between each pair.

Answers

Answer;

= (1/8), (2/8), (3/8), (4/8), (5/8), (6/8), and (7/8)

The positive fractions less than 1, with an interval of 1/8 between each pair are;

1/8, 2/8, 3/8, 4/8, 5/8, 6/8, and 7/8

-To represent these fractions on the number line, subdivide the interval between0 and 1 into eight smaller intervals

So,

Basically you are asking for all positive fractions that are less than 1.

$(0)/(8) , (1)/(8) , (2)/(8) , (3)/(8) , (4)/(8) , (5)/(8) , (6)/(8) , (7)/(8)$
