Sunlight pole height problem

The Relation between the height of the plant (y in cm) with respect to exposure to sunlight is governed by the following equation y=4x-1/2x^(2) where x is the numberof days exposed to sunlight. If the height of the plant is 7/2 cm, the number of days it has been exposed to the sunlight is ______ .

There are three poles, A, B and C. The height of pole C is (2)/(3) of pole B, the height of pole B is (4)/(3) of the pole A. Find the height of pole C, if the height of pole A is (97)/(3)m .

A vertical pole and a vertical tower are on the same level ground in such a way that from the top of the pole the angle of elevation of the top of the tower is 60^(@) and the angle of depression of the bottom of the tower is 30^(@) . Find : the height of the tower, it the height of the pole is 20 m ,

The horizontal distance between two poles is 15m. The angle of depression of the top of the first pole as seen from the top of the second pole is 30^@ . If the height of the second pole is 24 m, find the height of the first pole. (sqrt(3)=1. 732)

The horizontal distance between two poles is 15m. The angle of depression of the top of the first pole as seen from the top of the second pole is 30^o . If the height of the second pole is 24 m, find the height of the first pole. (sqrt(3)=1. 732)

The horizontal distance between two poles is 15 m. The angle of depression of the top of first pole as seen from the top of second pole is 30°. If the height of the second pole is 24 m, find the height of the first pole. Use v3 =1.732)

The horizontal distance between two poles is 15m. The angle of depression of the top of first pole as seen from the top of second pole is 30. If the height of the second pole is 24m, find the height of the first pole.Use v3=1.732)

A pole broken by the storm of wind and its top struck the ground at the angle of 30^(@) and at a distance of 20 m from the foot of the pole. The height of the pole before it was broken was
