HELP
Sam was asked to write the equation of a
parabola in class. He was given the
following information:
Focus: (5, 1) Directrix: y = -5
Opens upward
E
Sam wrote the equation 3(y + 2) = (x -
5)2. Which of the following best explains
if Sam was correct, or if he was
T
incorrect, the error that he needs to
correct.
A Sam is correct in his equation.
B Sam is incorrect. His equation should
reflect an h and k value that is the
same as the focus point.
C Sam is incorrect. His equation shows
the h and k values reversed and he
needs to square the y side of the
equation instead of the x side.
D Sam is incorrect. He forgot to multiply
the distance between the vertex and
focus points by 4.

At the olympic games, many events have several rounds of competition. one of these events is the men's 100-meter backstroke. the upper dot plot shows the times (in seconds) of the top 8 finishers in the final round of the 2012 olympics. the lower dot plot shows the times of the same 8 swimmers, but in the semifinal round. which pieces of information can be gathered from these dot plots? (remember that lower swim times are faster.) choose all answers that apply: a: the swimmers had faster times on average in the final round. b: the times in the final round vary noticeably more than the times in the semifinal round. c: none of the above.
