"He starts both trains at the same time. Train A returns to its starting point every 12 seconds and Train B returns to its starting point every 9 seconds". Basically, what you need to do is find the least common multiple. The least common multiple of 12 and 9 is 36, so the least amount of time, in seconds, that both trains will arrive at the starting points at the same time is 36 seconds.

I dont know how to find the orthocenter
AlladinOne [14]

Answer:

O = (3,3)

Explanation:

The <em>altitude</em> of a triangle is the perpendicular from a vertex to the opposite side.

The orthocentre (O) of a triangle is the point where the three vertices intersect.

We must find the equations for only two of the altitudes, because the third will also intersect at that point.

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

Your three points make a right triangle.

The altitude of B is side AC.

The altitude of C is sde AB.

Their point of intersection at A (3,3) is the orthocentre of thetriangle.

After putting 20% down on her $140,000 house, Esmeralda will be borrowing $112,000. The price of 2 points on that loan amount is 2%×$112,000 = $2,240. If Esmeralda applies that amount to the down payment, her loan amount will be $109,760 and her payment will be ...
  A = P*(r/n)/(1 -(1 +r/n)^(-nt))
  A = 109,760*(.0575/12)/(1 -(1 +.0575/12)^-360)
  A = 640.53

Esmeralda's monthly payment will be about $641.
