P is a point in rectangle ABCD. The distance from P to the 4 vertices of the rectangle are 7,15,24 and N in some order. If N is an integer, determine the value of N.

Physics
That's easy. From the given conditions, height= length/2

Math/Geometry
Two circles of radius r1 and r2 are extenally tangential to each other and are also externally tangential to a staight line l. Another circle of some unknown radius is externally tangential to both the circles and to the straight line l. Find the adius of that circle.

physics
We know how to calculate the total resistance of the cylindrical conductor given its length, radius, and resistivity. But how do we calculate the equivalent resistance when the resistivity is not constant? For example, say the resistivity at a particular point at a distance x ...

Geometry
Yes, solving gives HI^2= 792.
