A square with diagonals is shown. the distance from one point to the middle point is x. the length from the center point to anot

Rina8888 [55]

The approximate value of x in the square that the diagonals meets to form four right angles is 5.7 units

<h3>Properties of a square.</h3>

All the sides are equal.
Opposite sides are parallel to each other.
The diagonal intersects at right angle.

Using Pythagoras theorem the value of x can be found as follows:

c² = a² + b²

where

c = hypotenuse
a and b are other legs

Therefore,

8² = x² + x²

64 = 2x²

x² = 64 / 2

x = √32

x = 5.65685424949

x = 5.7 units

Based on the graph, what is the dependent variable, the equation relating the two variables, and how far will the dragonfly trav

ivann1987 [24]

Answer:

<h2>The dependent variable is distance, the equation is y = 20x, and the dragonfly will travel 480 miles.</h2>

Step-by-step explanation:

According to the graph, the dependent variable is Distance in miles, because it's on the vertical axis. Additionally, the independent variable is time in hours, because it's on the horizontal axis. However, you always put time as independent, because nothing affects time.

To find the equation, we just need to find the slope, using two points (0,0) and (2,40).

$m=\frac{y_{2} -y_{1} }{x_{2} -x_{1} }=\frac{40-0}{2-0}=20$

Therefore, the equation is $y=20x$ , which shows a direct proportion between variables.

Now, in 24 hours, it would travel

$y=20(24)=480$

It would travel 480 miles.

Therefore, the right answer is the second choice.
