Find the point on the x-axis which is equidistant from 2, â€” 5 and - 2, 9.

The chapter deals with an introduction to Arithmetic Progression with the help of simple daily life examples and gradually deals with the topic and its complexities. Find the zeroes of the following quadratic polynomials and verify the relationship between the zeros and the coefficients. Find the amount of each scholarship. In a retail market, fruit vendors were selling mangoes kept in packing boxes. Therefore, the given points are the vertices of a parallelogram. She uses the annual interest to give five scholarships to the students of a school for their overall performances each year.

In a classroom, 4 friends are seated at the points A, B, C and D as shown in the following figure. Download options are at the top of this page. Since , are two zeroes of the polynomial Let Squaring we get Let us divide p x by to obtain other zeroes. Page No: 170 Exercises 7. How much does a person have to pay for traveling a distance of 25 km? Prove that the area of an equilateral triangle described on one side of a square is equal to half the area of the equilateral triangle described on one of its diagonals. Find the number of students in the class.

Find the area of the triangle formed by joining the mid-points of the sides of the triangle whose vertices are 0, -1 , 2, 1 and 0, 3. AnswerLet the number of right answers and wrong answers be x and y respectively. Ans : i It is given that the sides of the triangle are 7 cm, 24 cm, and 25 cm. Therefore, they will not intersect each other and thus, there will not be any solution for these equations. According to the question, iv Places A and B are 100 km apart on a highway.

Page No: 53 Exercise 3. Using distance formula, find which of them is correct. A class teacher has the following absentee record of 40 students of a class for the whole term. Find the coordinates of the points of trisection of the line segment joining 4, -1 and -2, -3. Can you now find the distance between the two towns A and B discussed in Section 7.

Answer Let the ratio in which the line segment joining A 1, â€” 5 and B â€” 4, 5 is divided by x-axisbe. What is the distance between both the flags? Also please like, and share it with your friends!
