D.A.V_ school of Delhi decided different types of tours for the students to educate them. So, in class IXth times the square of the total number of students planned to visit historical monuments, th times the total number 12 of students planned to visit old age homes while remaining 15 students decided to teach poor children.

(i) using above information, express the total numbers of students as a polynomial in term of x.
(a) 2+2x+15 12 7x² (c) ² + + +15x (b) + x + 10 (d) = -x + 19 x + 15

(ii) Write the coefficient of x in the polynomial representing above situation. (a) 7/12 (b) - 7/12 (c) 15 (d) 7/4

(iii) Write the coefficient of x ^ 2 in the polynomial representing above situation. (a) 1/12 (b) 7/12 (c) 15 ( 1) 1 /4

(iv) Value of the polynomial at x = 2 (a) 33/2 (b) 11/2 (C) 14/3; 22/3

(v) Value of the polynomial at x = - 1 (a) 19/2 (b) 29/2 (C) 9/2 * (d) * 39/2​

Answer 2

Answer:

• Torque is the measure of the force that can cause an object to rotate about an axis. ... Hence, torque can be defined as the rotational equivalent of linear force. The point where the object rotates is called the axis of rotation. In physics, torque is simply the tendency of a force to turn or twist.
