Answer:

if you look at the graph closely it has the y axis (top circle limit) on 5 and bottom -6

Same on the x axis to the left -5 to the right circle 6

total amount from onside to another is 11 which make the diameter 11.

Radius? divide the diameter which is 11/2 = 5.5

it says it has been dilated. If it has been re-sized smaller then it B. 2.75

5.5 divided by 2 = 2.75

Step-by-step explanation:

Given bi-quadratic equation is:

$x^4+95x^2 -500=0$

Substituting $x^2=a,$ given bi-quadratic equation reduces in the form of following quadratic equation:

$a^2 +95a -500=0\\$

Let us factorize the above quadratic equation:

$a^2 +95a -500=0\\\therefore\: a^2 +100a -5a-500=0\\\therefore\: a(a +100) -5(a+100)=0\\\therefore\: (a +100)(a -5)=0\\\therefore\: (a +100)=0\:\: or \:\: (a -5)=0\\\therefore\: a = - 100\:\: or \:\: a = 5\\\\CASE\: (1)\:\\When\: a = - 100 \implies x^2 = - 100\\\therefore x=\pm \sqrt{-100}\\$
