A) cone
cone has no parallel bases all the others do
Answer:

Step-by-step explanation:
We want to find the equation of the line tangent to the graph of:

So, we will find the derivative of our equation first. Applying the chain rule, we acquire that:

Simplify:

We can factor out the denominator within the square root:

Simplify:

So, we can find the slope of the tangent line at <em>x</em> = 5/2. By substitution:

Evaluate:

We will also need the point at <em>x</em> = 5/2. Using our original equation, we acquire that:

So, a point is (5/2, π/6).
Finally, by using the point-slope form, we can write:

Distribute:

Isolate. Hence, our equation is:

There is a formula to find the slope (m)
(y2 - y1) / (x2 - x1)
So we now have y = mx + b where m is the value you just calculated
The y intercept (b) = y - mx
Plug in the x,y values for one of your points into this formula
