Answer:
B y+8 = 2(x-4)
Step-by-step explanation:
perpendicular slope is a negative reciprocal of the x
which is 2x
then use the formula
y-y1 = m(x-x1)
y + 8 = 2(x-4)
C=pid
Since d=9m and pi=3.142, C=3.142*9m=28.278
Rounded to 1 decimal point =28.3
Step-by-step explanation:
the first one is 4 and the second one is 11.6
