OH I KNOW I KNOW TEACHER. its its wait im in middle school what the heck am i doing in here.
Answer:
parallel line: y=-3x+14
perpendicular line: y=1/3x +2/3
Step-by-step explanation:
For the parallel line, use the point-slope formula to find the equation of the parallel line (since the slope is the same as the given line and the point (4,2) is given. For the perpendicular line, use the opposite reciprocal of the slope of the given line and use the point-slope formula again. The point-slope formula is Y-Y1=m(X-X1)
The circumference is the perimeter of the circle that is equal with
P=2πr(where r is the half of diameter)
P=2π10ft
=20ft
hope it helps
