In a model, it is shown that an arc of a bridge is semi elliptical with major axis horizontal. If the length of the base is 9m and the highest part of the bridge is 3m from the horizontal, then the height of the arch, 2m from the centre of the base is (in meters)

In a model, it is shown that an arc of a bridge in semi-elliptical with major axis horizontal. If the length of the base is 9 m and the highest part of the bridge is 3 m from the horizontal, the best approximation of the height of the arch at 2 m from the centre of the base is

An arc of a bridge is semi-elliptical with the major axis horizontal.If the length of the base is 9m and the highest part of the bridge is 3m from the horizontal,then prove that the best approximation of the height of the acr 2m from the center of the base is (8)/(3)m.

If the horizontal distance of the boat from the bridge is 25 m and the height of the bridge is 25 m, then find the angle of depression of the boat from the bridge.

The base of a triangle is four times its height and its area is 50 m^(2) . The length of its base is

A ladder resting on the wall is grounded 3 meters away from the base of the wall. If the length of the ladder is 5 m, what is the highest at which it is resting on the wall?

An arc is in the form of a semi-ellipse.It is 8m wide and 2m high at the centre.Find the height of the arch at a point 1.5m from one end.

An arch is in the form of a semiellipse.It is 8 m wide and 2m high at the centre.Find the height of the arch at a point 1.5m from one end.

A stone is thrown from a bridge at an angle of 30º down with the horizontal with a velocity of 25 m/s. If the stone strikes the water after 2.5 sec then calculate the height of the bridge from the water surface-
