Hi, is it better to do precipitation tests first or do flame tests first? I'm guessing that it would be better to do precipitation tests first then check with flame tests if suitable, since the flame test for Iron nitrate and Lead nitrate are toxic, however I just want to check. also, how do you...

For people that may look at this in the future, the final part is not the final answer. After doing that you have to sub x and y back into the volume equation to get the final answer of 21/1/3 cm^2

cool thanks!

Hi, this is completely unrelated to the question, but I was wondering how you got that formatting where you have actual fractions not use (8x19)/(x-7). Does advanced formatting for these posts have this function, do you use a website or ....? I'm sorry if it's a silly question.

Get Rich Bank P = $80 000 r = 0.075/12 = 0.0065 n = 12x10 = 120 A1 = 80 000(1.0065) - M A2 = 80 000(1.0065)2 - M(1+1.0065) A3 = 80 000(1.0065)3 - M(1+1.0065+1.00652) An = 80 000(1.0065)n - M(1+1.0065+1.00652+....+1.0065n-1) A120 = 80 000(1.0065)120 - M(1+1.0065+1.00652+....+1.0065119)...

Hi! Does anyone know how to do this question? A parabola with vertical axis has its vertex at the origin. Find the equation of the parabola if the line 12x − 4y + 3 = 0 is a tangent. Answer: y = -3(x^2) cambridge 9B q.12b Any help would be much appreciated!

Did you mean 1.5% monthly not 1.25% monthly? If so, I tried with r=0.015 and I got $513 which isn't the answer at the back of the textbook. It works with my original working out though. I think the authors worded the question poorly and meant '1.5%p.a. monthly'. Either that or I miraculously got...

Nope. So NSW Bank would be: T1=5000(1.0075) T2=5000(1.0075)^2 T3=5000(1.0075)^3 T4=5000(1.0075)^4 - M T5=5000(1.0075)^5 - M(1+1.0075) etc. etc. 2 year late reply for anyone that may be wondering this in the future.

2 years late but for those that are looking for the answer to this in the future, here's how to do it P = monthly repayment r = 0.015/12 = 0.00125 n = 5x12 = 60 Loan = $38 000 but, since they payed a 10% deposit, the amount that you work with is 38 000x0.9 = $34 200 A1 = 34 200(1.00125) - P...
