Answer:
C
Step-by-step explanation:
Since CB is a tangent to the circle then ∠ ABC = 90°
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, thus
AC² = 5² + 8² = 25 + 64 = 89 ( take the square root of both sides )
AC = → C

Answer:
to complete the square, you add (b/2)^2 on both side. in this case, b is -6, half of -6 is -3, -3 squared is 9, so:
x^2-6x+9=-13+9
(x-3)^2=-4
This quadratic equation have unreal solutions
Step-by-step explanation:
There would be 474 groups because if you divide 4,736 by 10 you get 473.6 or 473 remainder 6 and you know you can't say you put 4,736 marbles in 473.6 or groups. Thats just funny so you add one more group for the 6 marbles marbles to get 474 groups. Hope this helped. :)
