The equation of the circle whose centre is at point o' is x 2+32 x + y 2 - 24 y = 0 the coordinates of point a are (-34.794m. 18.840m). and those of point b are (-7.548m,30.126m). the tangents to the circle : line ac at a. and line bc at b intersect at point c. find the coordinates of point c to a precision of 1mm.

The equation x2 – 1x – 90 = 0 has solutions {a, b}. what is a + b?

Give all possible names for the line shown.calculation tip: lines can be written with either point first.

Finally, the arena decides to offer advertising space on the jerseys of the arena’s own amateur volley ball team. the arena wants the probability of being shortlisted to be 0.14. what is this as a percentage and a fraction? what is the probability of not being shortlisted? give your answer as a decimal. those shortlisted are entered into a final game of chance. there are six balls in a bag (2 blue balls, 2 green balls and 2 golden balls). to win, a company needs to take out two golden balls. the first ball is not replaced. what is the probability of any company winning advertising space on their volley ball team jerseys?
