The line segment AB is a chord of a circle centre (2,-1) where A and B are (3,7) and (-5,3) respectively. AC is a diameter of the circle. Find the area of ABC?

Area ABC = 59.9998 The best way to tackle this problem is to draw the question on a graph and plot each point. Once you’ve done this you’ll notice that AO is the radius (or half a diameter). Using coordinates, AO is (-1,-8). In triangle form this means that one length of the triangle AO is 8 and the other is 1. By using a^2=b^2+c^2, AO is the square root value of 8^2 + 1^2 which is 8.06226. This... more

Increase £14120 by 4%. Give your answer rounded to 2 decimal points?

The basic way is to find 4% of £14,120 and then add the amount to £14,120. £14,120 x 4% = £564.80 Increase of £14,120 by 4% = £14,120 + £564.80 = £14,684.80

How do you work out what the equation of the parallel line to my=2x+3 and passes through (0,7) is?

Parallel lines have the same gradient so the coefficient of x must still be 2. We know one set of x and y values so we can substitute in to get 7=0*2+c and rearrange to get c=7 Thus the equation of the parallel line is y=2x+7.
