PLEASE HURRY?! Which graph represents the parametric equations x = 3t and y = 1/2t^3-1 where -2< or =t< or=3?

step-by-step explanation:

i use my brain for prombles like this maybe you could try it

step-by-step explanation:

move it to the other side

step-by-step explanation:

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
