Question

As we know a tree or a plant needs both soil and water along with sunlight to
grow. It will have the necessary nourishment in both water and sun to make its
leaves green and fruit to grow. A rural Indian school Gardner planted some
trees on his school at certain distances from the water body following a sequence.
There are 25 trees at equal distances of 5 meters in a line with a well, the
distance of the well from the nearest tree being 10 meters. A gardener waters
all the trees separately starting from the well and he returns to the well after
watering each tree to get water for the next.

(i) Distance travelled to water nearest tree and back to the well is:
(ii) Progression so formed in the above condition is
(iii) Distance travelled to water 25th tree.
OR
The total distance the gardener will cover in order to water all the trees.

Answer

(i) 20m
(ii) 20, 30, 40, 50 .....
(iii) 260m OR 3500m

Smita always finds it confusing with the concepts of tangent and secant of a circle. But this time she has determined herself to get concepts easier. So, she started listing down the differences between tangent and secant of a circle, along with their relation. Here, some points in question form are listed by Smita in her notes. Try answering them to clear your concepts also.
  1. A line that intersects a circle exactly at two points is called:
  2. Number of tangents that can be drawn on a circle is:
  3. Number of tangents that can be drawn to a circle from a point not on it, is:
    Or
    Number of secants that can be drawn to a circle from a point on it is:

The angle of elevation of the top of a chimney from the top of a tower is 60º and the angle of depression of the foot of the chimney from the top of the tower is 30º. If the height of the tower is 40m, find the height of the chimney. According to pollution control norms, the minimum height of a smoke emitting chimney should be 100m. State if the height of the above mentioned chimney meets the pollution norms. What value is discussed in this question?
