PLEASE HELP!! 99 POINTS!! I HAVE NOOOO IDEA!
Otrada [13]
This is x^3+x^2+1=-x in math terms, where x is the number. So x^3+x^2+x+1=0. We can write this: x^2(x+1)+(x+1)=(x^2+1)(x+1)=0. The only real solution is x+1=0, so x=-1.
Hopefully that makes sense

Identify the equation for the circle with center (3, 7) that contains the point (9, 11).
Finger [1]

Answer:

(x-3)^2+(y-7)^2=2\sqrt{13}

Step-by-step explanation:

The equation of a circle:

(x-h)^2+(y-k)^2=r^2

(h, k) - center

r - radius

We have the center (4, -3) and the point on the circle (9, -3).

The length of radius is equal to the distance between a center and an any point on a circle.

The formula of a distance between two points:

r=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Susbtitute:

r=\sqrt{(9-3)^2+(11-7)^2}\\\\=\sqrt{6^2+4^2}\\\\=\sqrt{52}\\\\=2\sqrt{13}

The center (3, 7) → h = 3, k = 7.

Finally we have:

(x-3)^2+(y-7)^2=2\sqrt{13}
