I believe you meant: Use completing the square to determine the center and radius of the circle represented by this equation: <span>X^2+y^2-10x+6y=15
x^2 - 10x + 25 - 25 + y^2 + 6y + 9 - 9 = 15
Then:
(x-5)^2 + (y+3)^2 = 24 = 2sqrt(6)
This circle is centered at (5,-3) and has radius 2sqrt(6).</span>
15.49x = 13.99x + 6
15.49x - 13.99x = 6
1.50x = 6
x = 6 / 1.50
x = 4 <=== u can buy 4 DVD's for the same amount
15.49 * 4 = 61.96
13.99(4) + 6 = 61.96
The given figure can be drawn as,
From the figure,
Since angle of incidence will be equal to angle of reflection, 
Therefore, the height of cactus is 6 m.
Answer:
B
Step-by-step explanation:
Cube root 1000x^6 = 10x^2
Cube root of - 27 = 3
So the first part of the factorization process is 10x^2 - 3. There is no help here because all of the answers give this binomial as the first factor.
The second factor is (10x^2)^2 + (3)*10x^2 + 3^2)
Expanding you get 100x^4 + 30x^2 + 9
Be very careful when looking at 100x^4 because that is where the answer is found.
It has to be B
