ohexploitable u good with trig? maybe u can help me with just q18. on this post http://community.boredofstudies.org/13/mathematics-extension-1/243891/sigh-more-3d-trig.html

your solving part was right but the part wer u write wer x lies got mixed up but thanks x\leq -1, 0<x<1, x\geq \frac{3}{2}

question in the second line\frac{-1}{2} but then the on the third line its \frac{1}{2} how come the minus is gone?

Not sure how to use Latex Solve the inequality x-3 ------- >=-2 x^2-x btw. the >= stands for greater than or equal to

wen i first got the sheet the question werent that hard but now with only 3 questions left its doing my brain in 17. The side of a hill faces due south and is inclined to the horizon at an angle a (alpha). A straight railway upon it is inclined at an angle B (beta) to the horizon. If the...

very nice thanks for the sketchin+provin

not too sure the teacher photocopied out of some text book as cambridge dont have 3d trigonometry it says (problems on Heights and Distances - 3 Dimensions) on top and thats all and the exercise is EXERCISE SET 1E

ohexploitable got it right but i still dont get how the sketching would look like

AT TWO POINTS A AND B, 400 METRES APART, ON A STRAIGHT HORIZONTAL ROAD, he summit of a hill is observed. At A it is due N with an elevation of 40 degrees; at B it is due W with an elevation of 27 degrees. Find the height of the hill to the nearest 0.1 metre.

mm sorry ill make it more easier the brakets didnt occur to me ok 8. (3^2n + 25^(2n-1))/15^n-1 9.a) 4^-2 x 6^3 x 8^4 x 12^-2 b) (15^(n+1) x 25 x 5^(3n-4))/9^(n-1) x 25(n-2) Find x so that each of its true 11. (3 x 5^x -1)/5^x + 2=2

Simplify the following expressing them with positive indices (q8 and 9) 8.a) 3^2n/15^n-1 + 25^2n-1/15^n-1 9.a) 4^-2 x 6^3 x 8^4 x 12^-2 b) 15^n+1/9n-1 x 25^n-2 x 25/9n-1 x 25^n-2 x 5^3n-4/9n-1 x 25^n-2 find the value of x that makes each of the following true: 11.i) 3/5^x+2 x...

thanks was stuck in dat question only 1 person in the class acutually got the answer by themselves but still thanks really appreciated

Cambridge mathematics 3unit year 11 Exercise 1G 11.g) A certain tank can be filled by two pipes in 80minutes. The larger pipe by itself can fill the tank in 2 hours less then smaller pipe by its self. How long does each pipe take to fill the tank on its own. Any help would be appreciated Thanks
