<span>A shape has Rotational Symmetry when it still looks the same after a rotation.</span>
Answer:

Step-by-step explanation:
Cylinder volume formula is 




well the formula to reflecting across the x-axis is (x,-y).so the final points are A'(2,-2) B'(3,-7) C(5,-5) ANSWER
additional information
By the way the -y in the formula does not mean every number will always be negative it means switch the sign so if the point is (5,-7) than reflecting across the x-axis it would be (5,7)
<span>To solve it, use the quadratic formula with (½)(-32.174 ft/s²) = a, 38 ft/s = b, and 30 ft = c. There are two answers; the only positive answer is t = 2.986 s </span>
