Rationalize the following

IRINA_888 [86]

Step-by-step explanation:

$\frac{1}{ \sqrt{2} + 1 }$

(On Rationalizing )

$= \frac{1}{ \sqrt{2} + 1} \times \frac{ \sqrt{2} - 1}{ \sqrt{2} - 1 }$

$= \frac{ \sqrt{2} - 1 }{( { \sqrt{2} )}^{2} - {(1)}^{2} }$

$= \frac{ \sqrt{2} - 1}{2 - 1}$

$= \frac{ \sqrt{2} - 1}{1}$

$= \sqrt{2} - 1(ans)$

What would the answer for this question be

777dan777 [17]

Answer:

Step-by-step explanation:

The only one you can eliminate on sight is C. You are going to get an x^3 somewhere along the line.

You can eliminate D on sight as well. The x^3 term is 12x^3 not 7x^3

Doesn't leave much does it?

(3x + 2)(4x^2 - 2x - 7)

3x: 12x^3 - 6x^2 - 21x

2 : 8x^2 - 4x - 14

======================= Add

12x^3 + 2x^2 - 25x - 14

Tell whether the data in the table can be modeled by a linear equation. Explain.

Ludmilka [50]

Answer:

The table cannot be modeled by a linear equation.

Step-by-step explanation:

The data cannot be modeled by a linear equation because the rate of change is not constant.

If grab two set of points from the given data:

Let (x1, y1) = (1, 18)

(x2, y2) = (2, 15)

Plug these values into the slope formula:

$m = \frac{y2 - y1}{x2 - x1} = \frac{15 - 18}{2 - 1} = \frac{-3}{1} = -3$

Compare this slope with another set of ordered pairs:

(x1, y1) = (4, 12)

(x2, y2) = (8, 9)

$m = \frac{y2 - y1}{x2 - x1} = \frac{9 - 12}{8 - 4} = \frac{-3}{4}$

As you can see, the rate of change (slope) is not constant. Therefore, the given set of data cannot be modeled by a linear equation.
