Answer: Choice D

==========================================================

Explanation:

It might help to turn the image sideways so that it is rotated 90 degrees. Have the triangle facing upward with (x1,y2) and (x1,y1) as the base points. The base has a length of (y2-y1) as this is the difference of y coordinate values. The x coordinate being the same indicates we simply subtract. 

The height is (x3-x1) which is the difference of the x coordinates for either left point and the right point

So,
area = (1/2)*base*height
area = (1/2)*(y2-y1)*(x3-x1)
which is why choice D is the answer

Which one of the following is true when ds/st =3t^2/2s
Zina [86]
Middle school math!  I actually know how to teach differential calculus to middle schoolers, but I wouldn't start with this example, where we're gonna have to integrate eventually.

We have

\dfrac{ds}{dt} = \dfrac{3t^2}{2s}

We have an odd mix of s and t on the right, which means this probably was an implicit derivative to begin with.  In other words, instead of s as a function of t, we have some equation of s and t that is satisfied.

We move the variables to their respective sides 

2s \ ds = 3t^2 dt

Integrating,

s^2 =t^3 + C

We only need one constant of integration.

I won't bother to write the square root. This is choice D.
