If theta is an acute angle such that sin theta=5/13, what is the value of sin2 theta

cosӨ= 12/13 sin 2Ө= 2 sinӨcosӨ = 2 (5/13)(12/13) = 120/169-sin(2a) = 2sin(a)cos(a) now since a is acute and cos(a)= sqrt(1 - (5/13)^2) => cos(a) = 12/13 => sin(2a) = 2sin(a)cos(a) = 2 * (5/13) * (

How do you convert mol/dm^3 into g/dm^3 and give an example please? :)

you have dm^3 in both units so that does not change, you need to convert mol into g m=M*n m=mass [g] M=molar mass [g/mol] n=number of moles [1]-multiply it by the number on the periodic table! (the o

2^ 2x+1 = 3(2^x) - 1 = 0 how to solve this

Do i let 2^2x = y so it would be: y^2 = 3y - 1?-2^(2x + 1) = 3*(2^x) - 1 2*2^(2x) - 3*(2^x) + 1= 0 2*2^(2x) - 2*(2^x) - (2^x) + 1 = 0 (2*2^(x) - 1)(2^x - 1) = 0 2^x = 1/2 --> x = -1 2^x = 1 --

Help how would I solve x^-1 = -7

x^-1 = -7 => 1/x = -7 => x = -1/7-1/x = - 7 x = - 1/7-1/x = -7 x = -1/7-x^-1 = -7 1/x = -7 x = -1/7-a^-1 means inverse i.e,1/a 1/a=x=>a=1/x-x=-7 -7^-1=1/-7

Can you please answer these 6 math problems? i will give 10 pts

Please help me verify this identity? tan²x - sin² = tan²x sin²x

Remember these identities. tan²x = sin²x / cos²x sin²x = 1 - cos²x = tan²x - sin²x = [sin²x/cos²x] - sin²x = (sin²x - sin²xcos²x) / cos²x = sin²x(1 - cos²x) / cos²x = tan²xsin²x (Verified) Have a go

If you wanted to estimate a population mean where you know the standard deviation of the population is 152,

what is the smallest sample size you can have in order to get a margin of error less than 4 for a confidence level of 90%? (Remember n needs to be an integer). so I know the formula for margin of err
