Which transformation from the graph of a function f(x) describes the graph of 5f(x)? Part A: vertical or horizontal?
Part B: stretch or shift?
Part C: right, by a factor of, up, left, or down?

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

the answer would be a 24

step-by-step explanation:

c=2πr=2·π·3=24
