(4,7) cause its moving to the positive x side flipping on y axis the rule is (x,y) -> (-x,y) flipping over x axis the rule is (x,y) -> (x,-y) where - is opposite in each equation like a 5 turns into -5 or -3 turns into 3

Bashir works in a weather station and has launched a weather ballon. The height of the baloon is 4 kilometers and it is 1 kilome

andrew-mc [135]

<u><em>Answer:</em></u>

<u><em>Explanation:</em></u>

We are given that the height of the balloon is 4 km and that it is 1 km away from the station.

Setting up the diagram that describes the given scenario, we would end up with a right-angled triangle as the one shown in the attached image

<u>where:</u>

height of the balloon = 4 km represents one side of the triangle

distance between the base of the balloon and the station = 1 km represents the other side

distance between the balloon and the station is the length we want to find and it represents the hypotenuse of the triangle.

<u>To get the length of the hypotenuse, we will use the Pythagorean theorem</u>

$hypotenuse = +\sqrt{(side1)^2 + (side2)^2}$

<u>Substitute with the givens:</u>

$hypotenuse = +\sqrt{(4)^2 + (1)^2}$ = √17 ≈ 4.1 km

Hope this helps :)

There were 13426 eligible votes for a certain election.One day,8206 people cast their votes.What was the percent of voter turn o

coldgirl [10]

<h2>Greetings!</h2><h3>A way to do this is to divide the actual amount by the predicted amount:</h3>

8206 ÷ 13,426 = 0.6112

<h3>To change this back into a percentage simply multiply by 100:</h3>

0.6112 x 100 = 61.1

<h3>So the percent of voter turn out was 61.1%</h3><h2>Hope this helps!</h2>
