Answer:

C. (-4x^2)+2xy^2+[10x^2y+(-4x^2y)

Step-by-step explanation:

A. [9-4x2) + (-4x2y) + 10x2y] + 2xy2 : in this polynomial the first term is not a like term, then this is incorrect.

B. 10x2y + 2xy2 + [(-4x2) + (-4x2y)] : in this polynomial, the terms that are grouped, are not like terms, then is incorrect.

C. (-4x2) + 2xy2 + [10x2y + (-4x2y)] ; This polynomial is the right answer because the like terms are grouped.

D. [10x2y + 2xy2 + (-4x2y)] + (-4x2): This polynomial is incorrect because one of the terms that are grouped is not a like term.

Can the Pythagorean Theorem be used to find a distance in the coordinate plane?

Studentka2010 [4]

Answer:

Derived from the Pythagorean Theorem, the distance formula is used to find the distance between two points in the plane. The Pythagorean Theorem, a2+b2=c2 a 2 + b 2 = c 2 , is based on a right triangle where a and b are the lengths of the legs adjacent to the right angle, and c is the length of the hypotenuse.

What is the slope and y-intercept of the equation represented by the following graph?

Solnce55 [7]

Referring the chart I attached, the slope is the ratio of rise to run

So we need to pick two points lying on the line to calculate the slope.

They would be (4,0) and (0,2)

$slope= \frac{rise}{run} = \frac{\Delta y}{\Delta x}= 
\frac{y_2-y_1}{x_2-x_1} = \frac{2-0}{0-4} = -\frac{2}{4} = -\frac{1}{2} 
$

That is for the slope

The y-intercept is where the line touches\crosses\intersects the y-axis...

It is clear from the figure that the line crosses the y-axis at (0,2)
so the y-intercept is $y=2$

I hope that helps!

What is the interquartile range of the data set? {76, 22, 38, 95, 75, 60, 62, 92} Enter the answer in the box.

Naddik [55]

Hey!

I think before we solve this question we should know exactly what an interquartile rage is. The interquartile range is the difference between the third quartile and the first quartile in a data set. This gives the middle of the data set.

Now, the first step to solving this problem would be to set up our data from least to greatest.

Original Data Set :
76, 22, 38, 95, 75, 60, 62, 92

New Data Set {Old Data Set From Least to Greatest} :
22, 38, 60, 62, 75, 76, 92, 95

Now that that's done, we can go ahead and move on to our next step. The next step is to subtract quartile 3 from quartile 1.

New Equation :
Q3 - Q1 = IQ

Solution {New Equation Solved} :
35

So, now we know that the interquartile range of the data set you provided is 35.

Hope this helped!
