Reflect the point (-20,4)

Firdavs [7]

Refrection of (-20, 4) across x-axis gives (-20, 4) = (-20, -4)

Refrection of (-20, 4) across y-axis gives (20, 4)

Refrection of (-20, 4) across y = -x gives (20, -4)

Refrection of (-20, 4) across y = 7 gives (20, 10)

Identify the center and the radius of each.<br><br> x^+y^+26x-22y+281=0

inessss [21]

Answer:

Center (-13,11) , radius 3

Step-by-step explanation:

The given circle has equation

$x^2+y^2+26x-22y+281=0$

We compare this to the general equation.

$x^2+y^2+2ax+2by+c=0$

where (-a,-b) is the center.

This implies that;

2a=26

$\Rightarrow a=13$

2b=-22

b=-11

The center is therefore (-13,11)

The radius is given by

$r=\sqrt{a^2+b^2-c}$

$r=\sqrt{13^2+(-11)^2-281}$

$r=\sqrt{9}$

The radius is 3

If f(x) = 3x2 1 and g(x) = 1 – x, what is the value of (f –

pychu [463]

F(x) = 3x^2 + 1
g(x) = 1 - x
(f - g)(x) = 3x^2 + 1 - (1 - x) = 3x^2 + 1 - 1 + x = 3x^2 + x
(f - g)(2) = 3(2)^2 + 2 = 3(4) + 2 = 12 + 2 = 14.
