Answer:

(D)Prove that opposite sides are congruent and that the slopes of consecutive sides are opposite reciprocals

Step-by-step explanation:

Let us verify the choosen option

In Quadrilateral ABCD with points A(-2,0), B(0,-2), C(-3,-5), D(-5,-3)

Using the distance formula

Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

|AB|=\sqrt{(0-(-2))^2+(-2-0)^2}=\sqrt{8}=2\sqrt{2}\\|CD|=\sqrt{(-5+3))^2+(-3+5)^2}=\sqrt{8}=2\sqrt{2}\\|BC|=\sqrt{(-3-0))^2+(-5+2)^2}=\sqrt{18}=3\sqrt{2}\\|AD|=\sqrt{(-5+2)^2+(-3-0)^2}=\sqrt{18}=3\sqrt{2}\\

Since |AB| is congruent to |CD| and |BC| is congruent to |AD|, we conclude that opposite sides are congruent.

Next, let us consider the slope.

Slope of |AB|= \frac{-2-0}{0-(-2)} =\frac{-2}{2}=-1

Slope of |BC|=\frac{-5+2}{-3-0} =\frac{-3}{-3}=1

Since the slopes of consecutive sides are opposite reciprocals, therefore ABCD is a rectangle.

<u>Option D is the correct option.</u>

What is the scientific notation of 0.00165?
Ierofanga [76]

Answer:

The answer is 1.65*10^{-3}

Step-by-step explanation:

when writing scientific notation, there must be one number to the left of the decimal point.

To achieve this in this problem, you need to move the decimal point 3 times to the right.

because you are moving the point to the right, the exponent will be negative.

*rule of thumb: moving the decimal to the left will give you a positive exponent, moving to the right will give you a negative exponent*

therefore you answer should be written as:

1.65*10^{-3}

hope this helps :)

Find inverse of f(x)=x^3-9<br>Not sure of my answer!​
Katyanochek1 [597]

as you may already know, to get the inverse of any expression, we start off by doing a quick switcheroo on the variables, and then solve for "y".

\bf \stackrel{f(x)}{y}=x^3-9\implies \stackrel{\textit{quick switcheroo}}{\underline{x}=\underline{y}^3-9}\implies x+9=y^3\implies \sqrt[3]{x+9}=\stackrel{f^{-1}(x)}{y}

You can draw a quadrilateral with two sets of parallel lines and no right angles?
bonufazy [111]
Yes you can. The quadrilateral that you would get is called parallelogram. It has 2 paris of parallel lines. and 2 pairs of equal angles. one pair is angles that are less than 90 degrees and other one is where 2 angles are greater than 90 degrees each. Therefore there isnt any right angle there and you got yourself quadrilateral. of these 2 parallel lines are of equal lenght than you get something called rhombus.
