Vertical Curve Problem Given: Two tangents to a roadway profile intersect at an elevation of 100. The first tangent is at a 2% uphill grade and the second tangent is a -5% downhill grade. Calculate the equation ofa 200 ft parabolic curve connecting the two tangents and the elevation at themid point of the curve. Let the “x” origin be at the beginning of the curve. See More
"This is a great question. Common assessments can be done well or poorly.
The most effective way, in my experience, is to have a "lead" teacher for a particular course, (for the purpose of this discussion, I will use Geometry) or in a…"
"Working backwards, knowing that the height of the tower is 828 m, I calculate that it can be seen from about 102.7 km away (not 95 km). The Distance to Horizon Calculator's answer is consistent with this information. Using your value of 95 km,…"
"I got the same answer as Colin.
Tools for this solution:
45-45-90 right triangle relations
Area of a circle
Area of a square (half product of the diagonals, and side squared)
There are 3 squares:
The large one... let…"
Glad to see U here.
Welcome to Mathematics 24x7. The purpose of this network is to just talk about all possibilities in Mathematics .There are people who love this subject and at the same time there are ones who are struggling for it.
Let us join our hands and look for all possibilities to make it interesting for everybody.
Thanks for joining this network.
