straight-line method

A particle moves along a straight line with the relation between the time and distance ( s ) in such a way that s = 9 - 5 t 2 + 10 t 3 . At what time will the acceleration be 230 units/sec 2 ? => 300 sec or 1 4 sec or 4 sec or 11 3 sec or 280 sec..

Let LM be a straight line parallel to y-axis at a distance k from the y-axis. Then, the abscissa (the x-coordinate), x=k. Hence, the equation of the line parallel to y-axis is x = k. ..

Let AB be a straight line passing through B (h, k) with slope m. Let P (x, y) be any point on the line. From the right-angled triangle BPC, we have ..

The distance S of a body moving along a straight line is related with its velocity v , traversed time t as S = vt + 2. What is the acceleration of the body at any time t in terms of v ? => V units or 0 or 2V units or V 2 units..

In ΔABC, AB = AC. Straight line L cuts AB ‾ and AC ‾ at P, Q and BC ‾ produced at R. What is the relation between AP ‾ and AQ ‾ ? => AP < AQ or AP = AQ or AP > AQ or cannot be determined with the given data..

To show that a homogenous equation of degree n in x and y represents n straight lines passing through the origi..

A teacher wishes to know whether there is any relationship between the hours of study and the test scores of the students. Ten students were selected randomly and were given a test. Test the hypothesis that there is a significant relationship between hours of study and test scores at α = 0.01..

Line segments AB ‾ and DC ‾ bisect each other at 90° as shown. What is the locus of the point A if AB ‾ makes a complete revolution with respect to E? => A straight line or A circle or An ellipse or A rectangle..

The position of a point in a plane is determined by two coordinates. The method is as follows: Two mutually perpendicular lines (straight lines) XX' and YY' are drawn as shown in the figure. These straight lines are termed as coordinate ax..

Rectangular coordinate system - The position of a point in a plane is determined by two coordinates. The method is as follows: Two mutually perpendicular lines (straight lines) XX' and YY' are drawn as shown in the figure. These straight linesh..
