15 because there are 10 of the 25. if you add an additional 75 people approx 10 more play disc golf so 5 of those have a personalized disc
Simply take the derivative of s(t),
s'(t) = -6
Since the velocity is constant, v(t) = s'(t) = -6 at any given time t.
For the equation of the line expressed as Ax + By + C = 0, the value of the slope (m) is calculated by -A / B. For perpendicular lines, the slope of one should be the negative reciprocal of the other. From the choices given, the lines that are perpendicular is Option A.
No - It is a function.
