The pair of triangles below have two corresponding parts marked as congruent. What additional information is needed for a SSS congruence correspondence?

True, but now it isn't a little more than  $5,000, it's more than $10,000 due to inflation, higher taxes, and bad economy.

You're asking in the ap section, so i'll give the ap calculus-style answer. alternatively, you can find the vertex of the parabola and use the "y"-coordinate as the answer.

the maximum height can occur at a critical number, that is, a number  such that  .

the derivative of  can be calculated as follows:



find a value of  that is a zero of the derivative:


this is parabola that is opening downward; we can assume there is a maximum at  .

to find that maximum, calculate  .
