What are the center and radius of the circle with equation (−)+(−)=?Open x minus 4 close squared . Plus . Open y minus 9 close s

lbvjy [14]

Answer:

Center and radius of the circle of the equation ${(x - 4)^{2} + (y - 9)^{2} = 1$

center = ( 4,9) Radius = 1

Step-by-step explanation:

Given -

Equation of circle is $(x - 4)^{2} + (y - 9)^{2} = 1$

The equation of circle is represented by

$\boldsymbol{\mathbf{(x - a)^{2} + (y - b)^{2} = r^{2}}}$

where a and b are center of circle and radius r

Comparing these equation

then a = 4 and b = 9 and r = 1

Find the vertex of f(x) = 3(x-7)(x+5)

Inessa05 [86]

Answer:

The vertex is at (1, -108).

Step-by-step explanation:

We have the function:

$f(x)=3(x-7)(x+5)$

And we want to find its vertex point.

Note that this is in factored form. Hence, our roots/zeros are x = 7 and x = -5.

Since a parabola is symmetric along its vertex, the x-coordinate of the vertex is halfway between the two zeros. Hence:

$\displaystyle x=\frac{7+(-5)}{2}=\frac{2}{2}=1$

To find the y-coordinate, substitute this back into the function. Hence:

$f(1)=3((1)-7)((1)+5)=3(-6)(6)=-108$

Therefore, our vertex is at (1, -108).
