A circle has a diameter with endpoints (-8, 2) and (-2, 6).<br> What is the equation of the circle?

choli [55]

Answer:

Step-by-step explanation:

Alright, lets get started.

We have given two points that are end point of diameter.

So, the center point will be :

x co-ordinate : $\frac{-8-2}{2}=-5$

y co-ordinate : $\frac{2+6}{2}=4$

Hence the center is : (-5,4)

Now the distance between these two end points :

$d=\sqrt{(6-2)^2+(-2+8)^2}$

$d=\sqrt{16+36}$

$d=\sqrt{52}$

So radius will be half of this diameter.

$r=\frac{\sqrt{52} }{2}$

Plugging these values in standard equation of circle

$(x-x_{1} )^2+(y-y_{1} )^2=r^2$

$(x+5)^2+(y-4)^2=\frac{52}{4}$

$(x+5)^2+(y-4)^2=13$ .................................. This is the answer

Hope it will help :)

Jake went on a riverboat tour. After returning from the tour, he was curious to know the speed at which the boat was going. Duri

atroni [7]

I'm sorry I'm too lazy to read all of that. However, I did get the main point. The river was going at 3 mph. Since he wanted to travel 10 miles upstream and downstream, you would have to subtract 20 by 3. This would mean he was going at a speed of 17 mph.

How would you solve this? x^2 = 169

pashok25 [27]

Answer: x = 13

Step 1:

To get rid of the ^2 on the x you need to square root it and what you do to one side you need to do to the other so: √x^2 = √(169)

Step 2:

The square root of 169 is 13 so x = 13

I hope this helped :)
