38.1 seconds I believe simply divide 4m/s into 152.4 m and you will have 38.1 seconds
So i believe you need to round the whole number, if so than 8 * 3 = 24 and 20 * 3 = 60
1) True that line x = 0 is perpedicular to y = -3. Because x = 0 is parallel to the y-axis and y = -3 is parallel to the x-axis.
2) True that all the lines that are parallel to the y-axis are vertucal lines (the y-axis is vertical)
3) False that all lines perpendicular to the x-axis have a slope o 0. Their slope trends to infinity.
4) False that the equation of the line parallel to the x-axis that passes through the point (2, –6) is x = 2. The right equation is y = - 6
5) True thath the equation of the line perpendicular to the y-axis that passes through the point (–5, 1) is y = 1
Yes, any question that involves numbers would be a statistical question.
