Answerthe distance to nearby stars;

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  .

the correct answer is:

b. substitution property.

if the circle m is with inscribed ∠kjl and congruent radii jm and ml then m = ∠mjl = (kl) because of the substitution property.
