One of the equations for a circle is (x - h)² + (y - k)² = r² where (h, k) are the center and r is the radius.
So after substitution:
(x + 6)² + (y - 2)² = 100
Notice the equation has the opposite of h and k and 100 is the result of squaring 10.
Answer:
-40
Step-by-step explanation:
A^2 + b^2 = c^2
C is your hypotenuse or the longest side of the triangle; you plug in your values and solve for the missing side:
15^2 + b^2 = 17^2
225 + b^2 = 289
*-225 on both sides to get b by itself*
B^2 = 64
*to get rid of the ^2; you take the square root*
B = sqrt 64
B= 8 <— final answer
Answer:
17+3/4
Step-by-step explanation:
Answer:
[g+2/3g-1] ÷ [g^2+2g/6g+2]
g+2/3g-1 × 6g+2/g^2+2g
g+2/3g-1 × 2(3g +1)/g(g+2)
1/ 3g-1 × 2(3g+1)/g
2(3g +1)÷ g(3g-1)
6g+2 ÷[3g^2-g]
