Which of the following equations would transform the tangent graph to the parent cotangent graph?

a) y=tan(x+pi/2)

b) y=-tan(x-pi)

c) y=-tan(-x-pi/2)

d) y=-tan(x-pi/2)

D

Step-by-step explanation:

First you need to make it either -tan(x) or tan(-x) to get it oriented correctly (Flipped over the x or y axis, either works) and then moved left or right by pi/2, again, either works.  You cannot have both tangent itself and x be negative though, like in C, because that just undoes the flipping.    just like a +pi/2 would undo a-pi/2.

answer: are you

step-by-step explanation:

answer: the answer is 30 miles per hour.

ft/s -> mphmph = ft/s 1.466667mph = 44 divided by 1.466667mph = 30.00000
