State the radius of the circle of the equation

Eva8 [605]

Answer:

radius = √5 = 2.24 to nearest hundredth.

Step-by-step explanation:

(x + 3)^2 + (y + 3)^2 = 5 comparing with the standard form

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

-h = 2 so h = -3, -k = 3 so k = -3.

r^2 = 5 so r = √5.

Complete the square than convert to vertex form. y=2x^2+8x-9

8_murik_8 [283]

$y=2x^2+8x-9\\D=b^2-4ac\\D=64-4(2)(-9)\\D=64+72 > 0$

There are 2 roots so the only way to complete the square is,

$y=2x^2+8x-9\\y=2[(x^2+4x)]-9\\y=2[(x^2+4x+4)-4]-9\\y=2[(x+2)^2-4]-9\\y=2(x+2)^2-8-9\\y=2(x+2)^2-17$

Just factor 2 out of 2x^2+8x (just ignore the -9) then find the number that will make the terms be able to complete the square.

then complete the square and multiply 2 inside the brackets.

subtraction as you already get the vertex form and know how to complete the square.

Vertex Form: $y=2(x+2)^2-17$

8x + (2x - 14)= 7x + 3x -14

10x -14= 10x - 14

These equations are identical, so it would be the identity property and the answer would either be identity or the fancy 'R'.
