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

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!

Find the area of the circle then, multiply that by the height of the cylinder.

Area of a circle = PI x r^2

Area = PI x 8^2 = 64PI

Volume = 64PI x 11 = 704PI in^3

Answer:

x=9

Step-by-step explanation:

.5x+.7 = .3x+2.5

-.7 -.3x

.2x=1.8

/.2 /.2

x=9

.5(9)+.7=5.2

.3(9)+2.5=5.2

Easy points..........

IRINA_888 [86]

Answer:

38°; 142°; 308°

Step-by-step explanation:

The solution of each question is self-explanatory.

<u>Used properties</u>

Vertical angles are congruent
Angle sum property of circle
Central angle is same as intercepted arc measure

mED = mAB = mAC - mBC = 90° - 52° = 38°

mEA = mBCD = mBC + mCD = 52° + 90° = 142°

mBDC = 360° - mBC = 360° - 52° = 308°
