IMPORTANT:
What type of variation does this formula represent?

anonymous · Answer

well what formula is it?

anonymous · Answer

The formula for final velocity of an object starting from zero and undergoing constant acceleration is $$v=\frac{ 1 }{ 2}at^2$$ What type of variation does this formula represent?

Combined variation, inverse variation, direct variation or joint variation?

whpalmer4 · Answer

you have $v$ varying somehow with $t^2$ right?

by the way, that formula Is NOT correct!

anonymous · Answer

Yeah, I remember from what you told me earlier ): It surprises me that they'd put an incorrect formula on A Plus.

whpalmer4 · Answer

direct variation of x with y:  y = kx
indirect variation of x with y:  y = k/x or xy = k
joint variation of z with x and y:  z = xy
combined variation is just any mixture of the above, such as 

z = xy/r^2  which would be joint variation of x and y with inverse variation with r^2
