In the given figure, O is the centre of the circle. . Tangents at A and B meet at C.
It was an Indian scientist Aryabhatta, who coined the concept of zero. In what ratio does the point M P, -1 divide the line segment joining the points A 1,-3 and B 6,2? As observed from the top of a 100 m high light house, the angles, of depression of two ships approaching it are 30° and 45°. The ratio of the prices of two fans was 16: 23. Find the radius of the tube and the length of its cylinderical part. Mathematics has been dated back to ancient times and its applications are found in life's daily activities - from calculating taxes, calculating grocery bills, and finding its uses in more diverse applications like engineering solutions, computational process, and other systems. Students are given a pre-assessment test to test out their current problem-solving abilities and get insights on weak subject areas. State for each of the following statements whether it is true or false : a If x — a x — b 0.
If the tangents at P and Q intersect at point T; show that the points P, B, Q and T arc concyclic. With Vedantu's live mentorship sessions, pre-recorded lessons, and interactive digital online learning tools, students can interact with their mentors one-on-one and get their queries answered. A bag contains a red ball, a blue ball and a yellow ball, all the balls being of the same size. Vedantu gives you the competitive edge For those who require additional guidance, students can enrol at Vedantu, India's leading education platform. Use graph paper for this questions.
These Selina textbook solutions can be a core help for self-study and acts as a perfect self-help guidance for students. If you have any doubts while going through our Class 10 Mathematics Selina solutions, then you can go through our Video Tutorials for Mathematics. Two dice are thrown at the same time. It is in a very simple and conscience manner so that the readers are able to follow easily. A model of a ship is made to a scale of 1 : 160. Plot these points also on the same graph paper. By interacting with a Vedantu mentor, one can overcome these blocks of confusion and learn Maths in a simplified, easy-to-understand approach.
Calculate the area of the shaded portion. A cylindrical bucket 28 cm in diameter and 72 cm high is full of water. The tangents at B and D intersect each other at point P. Find : i the length of the ship, if the length of its model is 1. Find: i the length ii the volume of the wire Solution: Question 92. A common tangent touches the circles at P and Q. What is the probability that this bulb is defective? From the top of a light house, it is observed that a ship is sailing directly towards it and the angle of depression of the ship changes from 30° to 45° in 10 minutes.
The tutorials should help you better understand the concepts. Given points A l, 5 , B -3,7 and C 15,9. Now one bulb is drawn at random from the rest. Give reason in support of your answer. The water is emptied into a rectangular tank 66 cm long and 28 cm wide. Get the free view of Class 10 Mathematics chapter 12 Reflection and can use shaalaa. Find the radii of the three circles.
