Thanks all for helping out, the questions for final part has the answer of 35.46 cm, so still thinking about it .

A give way sign with shape of an equilateral triangle has side length of 87 cm. The sigh is attached in two places to a metal pole. How far from the top of the sign should the holes be drilled if the top hole divides the vertical height of the sign in the ratio 1:9 and the bottom in the ratio...

how to find points of intersection of px + qy =1 and qx + py =1 and explain why the lines intersect on line y =x ?

How would you describe in words the process of back titrating? given two equations Stage 1: NH3 (aq) + HCl (aq) → NH4Cl (aq) Stage 2: 2HCl (aq) + Na2CO3 (aq) → 2NaCl (aq) + CO2 (g) + H20 (l)

When is back titration is the most effective technique to use in some chemical processes? I know some include the insoluble solids..

How did you figure out the curve was a circle?

Do you mean like this (y +2) (y-4) / (x-4) (x+4) = -1 which leads to y-2y = -1x +24?

Im thinking possibly perpendicular distance. however, didn't say on the question.

The points A (4,-2) , B (-4,4) and P (x,y) form a right angle at P. Form an equation in x and y. hence find the equation of the curve on which P lies? How to find the equation?

The overall heading of the exercise is gradients of intervals and lines. This chapter covers the perpendicular distance. It hints saying that the distance between two intercepts of one pair of lines must equal the distance between the y inc on other pair?

y= 2x+1 , y=2x -1 , y =3-1/2x , y =k-1/2x What are the possible values of K if the lines enclose a square?

How to divide the line segment of points A (1,7) and B(4,1) externally in ratio of 1:2 using the first principle method.??

Thankyou, Very Appreciated, your answer was more simple. :)

A rhombus with vertices A (1,6) B (6,6) C (-2, 2) and D (x, y) A rhombus with vertices A (1,6) B (6,6) C (-2, 2) and D (x, y) Find the coordinates of D? I attempted distance formula and simultaneous equations. But the xs and ys kept cancelling out.
