Select the functions that have identical graphs . 1)y=cos x 2)y=cos (x- 5x 2 ) 3)y=sin x

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

answer: $13,622.84

step-by-step explanation: check the picture for info and stats : )

b

step-by-step explanation:

multiply terms on numerator/ denominator by (x - 1)

= ← distribute numerator/ denominator

= ← simplify

=

= → b

the easiest way to do these would be to solve the equations. if you can solve the equation than you can solve these problems.
