Answer:
<h2>radius of 8</h2>
Step-by-step explanation:
step one :
Given that the equation of the circle is described as
![x^2 + y^2 = 64](https://tex.z-dn.net/?f=x%5E2%20%2B%20y%5E2%20%3D%2064)
To correctly identify the center of the circle we have to place the equation in the standard form.
the standard equation for a circle is
![(x-h)^2+(x-k)^2= r^2](https://tex.z-dn.net/?f=%28x-h%29%5E2%2B%28x-k%29%5E2%3D%20r%5E2)
step two :
let us re-write the given equation so that we can compare it with the general equation of circle
![(x-0)^2+(x-0)^2= 8^2](https://tex.z-dn.net/?f=%28x-0%29%5E2%2B%28x-0%29%5E2%3D%208%5E2)
step three:
From this above equation in step two we can see that the circle has a radius of 8
Answer:
1 2
2 6
3 12
Step-by-step explanation:
pattern number is input
tiles number is output.
pattern number 1 has two tiles (first coordinates are (1,2))
pattern number 2 has 6 tiles (second coordinates are (2,6))
pattern number 3 has 12 tiles (last coordinate is (3,12))
answer:
1 2
2 6
3 12
g(x) = 4x−8, find g(1/2)
Replace x with 1/2 and solve.
4(1/2) - 8
= 2 - 8
= -6
The answer is -6
The pythagroean theorem says a² + b² = c² and we're given a and c in this case
12² + b² = 13²
144 + b² = 169; subtract 144 from both sides
b² = 25; square root both sides
b = 5 so the length of side AB is C) 5
