finding x and y

A shop earned the profit $P at the end of the first year. In the second year, the company profit increased by $x, and in the third year it increased by $y. At the end of the third year, the company profit would be $P + ($x + $y). Find the equivalent..

Graph of y = sin x - Now let us construct the graph of y = sinx from x = 0 o to 360 o . The following table is readily constructed for intervals of 30 o . Plotting the points and drawing a smooth curve through them we have the curve as shown in figur..

As x increases from 180 o to 270 o , sinx decreases from 0 to -1 and as x increases from 270 o to 360 o , sinx increases from -1 to 0. The maximum absolute value of sin x = ..

A truck leaves at 9:00 A.M. from city X to go to city Y. The line graph represents the distance traveled by the truck, with respect to time. The distance between the two cities is 150 km. Find the time taken by the truck to go to city Y from city X...

Which is the closest to the value of the midpoint between points X and Y? => - 1 or 1 or 2 or 0..

Let AB represent the given line xcos a + ysin a = p. Let N' (x1, y1) be the given point. Through N', draw B'N'A'|| BA, so that OM produced will meet B'A' at N. Then, MN = M'N' = p'. ON = OM + MN = p + p' The equation of the line A'N'B' is xcos a + ysin a = p +..

∠ X is a supplement of ∠ Y and ∠ Y = 9°. Find ∠ X. => 81° or 181° or 79° or 171°..

Solve the system using Cramer's rule x - y + 6 = - z y + 1 = -z x + 1 = z => (- 2, 2, - 2) or (- 3, 1, - 2) or (- 4, - 1, - 3) or (1, 3, - 4)..

If y = 9 x sin -1 2 x , then find y′ => 9sin -1 2 x + 1 8 x 1 + 4 x ² or 9sin -1 2 x + 1 8 x 1 - 4 x ² or 9sin -1 2 x - 1 8 x 1 - 4 x ² or..

If y = ln tan 7 x , then find d y d x . => 7sec 7 x cosec 7 x or sec 7 x cosec 7 x or sec x cosec 7 x or 7sec 7 x cosec x..
