I'm unsure on how to do 8,9, and 11.

1 answer:

8 0

X^2 - 16x + 56 = 0

= (x - 8)^2 - 64 +56= 0
= (x - 8)^2 - 8 = 0

x^2 - 8x + 11 = 0
(x - 4)^2 - 16 + 11
(x - 4)^2 - 5 = 0

(x + 15)(x + 5) = 96

x^2 + 20x + 75 = 96

(x + 10)^2 - 100 + 75 = 96
(x + 10)^2 = 96 +25 = 121
taking square roots:-

x + 10 = 11
x = 1

Area of a circle is:
A = (3.14)r^2

The picture shown is that the radius is 4

So,

A = (3.14)4^2

A = 50.2

The circle below is centered at the point 4, 1 and has a radius of length 2 what is its equation

Alisiya [41]

$\bf \textit{equation of a circle}\\\\ (x- h)^2+(y- k)^2= r^2 \qquad center~~(\stackrel{4}{ h},\stackrel{1}{ k})\qquad \qquad radius=\stackrel{2}{ r} \\\\\\ (x-4)^2+(y-1)^2=2^2\implies (x-4)^2+(y-1)^2=4$
