Point Z is the circumcenter of ΔLMN. Point Z is the circumcenter of triangle L M N. Lines are drawn from each point of the triangle to point Z. Lines are drawn from point Z to each side to form right angles and line segments Z A, Z B, and Z C. Which must be true? Line segment A N is-congruent-to line segment L B Line segment N C is-congruent-to line segment B Z AngleBMZ Is-congruent-to AngleCMZ AngleZBM Is-congruent-to AngleZCM

i think is g(1)=-1.

hope that i can

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:

  ⇒

then, the solutions are: or

nothing extraneous has been found!

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
