Angle α (in radians) subtended at the centre of a circle of radius R by an arc of length A is α = A/R radians = 180A/πR degrees Example: Arc = π/2 m Radius = 3 m Angle = (π/2)/3 radian =π/6 radian

The molality is then M mol /(1000 g/kg /( m -10 g)
In scientific calculations, it is important to know how accurate you'd like your answers. If you see a number like 0.9864g/ml, it means 4 significant figures are expected, so you have to carry your calculations to at least 5 significant digits, and then round off to 4 for ...
To calculate the percentage, you would - divide part by total - multiply fraction by 100% - simplify For example, if you have 14 sums correct out of 20, then 14 is the "part", 20 is the "total", so - divide 14/20 = 7/10 - multiply by 100% : 7/10*100% - simp...
"mike runs for 5 of an hour " Please clarify 5 (what) of an hour, it could be 5%, 5 minutes, or one-fifth, ...
tom, chris, charls, TIM, lorra, lindy: please do not use different aliases. AB = A^B-(A+B) for 34, substitute A=3, B=4, rewrite the equation as: 34=3^4-(3+4)=81-7=74 You can do the same for 79. If you wish, you can post your answer for checking.
Calculate the present value of the investments using the compound interest formula over the past 10 years, or n=120 periods (t) at interest rate of i=0.0384/12=0.0032 per period. The monthly payment P=$625 per period, and therefore PV = present value FV = (i.e. future value fr...
Should read: y"=0+2sec(x)*(-1/cos²(x))(-sin(x)) =2sec²(x)tan(x)
y=x+tan(x) y'=1+sec(x)^2 y"=0+2sec(x)*(-1/cos²(x))(-sin(x)) =sec²(x)tan(x) => cos²(x)y"-2y+2x =2cos²(x)sec²(x)tan(x)-2(x+tan(x)+2x =2tan(x)-2x-2tan(x)+2x =0
There is no diagram posted, and not enough description to give a defined question. I am adding the following guesses. Check if they are correct. If they are not, post the complete description. AMB is a straight line such that AM=MB. Semicircles are drawn with AB,AM and MB as d...
