How many degrees are in an angle that turns through 3/4 of a circle?

1 answer:

8 0

The answer is 270 degrees.

Since a circle has a full degree measure of 360 degrees, we can multiply 360 by 3/4 to result in 270 degrees.

Hope this helps.

X²+y²-6x+14y-1=0<br> and please show your work so I can learn

Eva8 [605]

Hello there,

I hope you and your family are staying safe and healthy during this winter season.

$x^2 + y^2 -6x+14y-1=0$

We need to use the Quadratic Formula*

$x =\frac{-b+\sqrt{b^2}-4ac }{2a}$ , $\frac{-b-\sqrt{b^2} -4ac }{2a}$

Thus, given the problem:

$a = 1, b=-6, c=y^2+14y-1$

So now we just need to plug them in the Quadratic Formula*

$x=\frac{6+2\sqrt{(-6)^2-4(y^2+14y-1)} }{2}$ , $x=\frac{6-\sqrt{(-6)^2-4(y^2+14y-1)} }{2}$

As you can see, it is a mess right now. Therefore, we need to simplify it

$x=\frac{6+2\sqrt{10-y^2-14y} }{2}$ , $x = \frac{6-2\sqrt{10-y^2-14y} }{2}$

Now that's get us to the final solution:

$x=3+\sqrt{10-y^2-14y}$ , $x=3-\sqrt{10-y^2-14y}$

It is my pleasure to help students like you! If you have additional questions, please let me know.

Take care!

Is 4/6 greater than 9/12

Liono4ka [1.6K]

You start by cross multiplying.
4 x 12 = 48
Therefore, the value of 4/6 is equal to 48.
You do the same on the other side.
6 x 9 = 54
Therefore, the value of 9/12 is equal to 54.

No. 9/12 is greater than 4/6.
