An=12Cn*x^(12-n)*y^n, n=0,1,2,3,...,12 A6=12C6*x^6*y^6 12C6=924 BTW, mCn=m!/(n!(m-n)!)
The present value An of the annuity=10,000 An=p*(1-(1+i)^-n)/i 10000=750*(1-1.05^-n)/0.05 500=750*(1-1.05^-n) 2/3=1-1.05^-n 1.05^-n=1/3 1.05^n=3 n=ln3/ln1.05=22.51708531
(1+ nominal rate)= =(1+ inflation rate)(1+ risk free rate)
I mean cos(-0.000000001)/sin(-0.000000001)= =-999999999
sin(-0.000000001)=-0.000000001 cos(-0.000000001)=0.999999999 sin/cos=-999999999
Consider the geometric method. b(b>0)- is the leg in a isosceles rectangular triangle with height=6 6^2+6^2=b^2
Draw two tangents to the circle x^2+y^2=6^2 parallel to the line y=x in the second and fourth quadrants. b is y-intercept of these tangents. Сonsider the algebraic method. Find the coordinates of common points of the line and circle: x^2+(x+b)^2=36 2x^2+2bx+b^2-36=0 Sinc...

If you say a system is consistent, it means that it can be solved. If you say a system is inconsistent, it means that the system has no solution. If a system is dependent, it has infinite solutions and if it is independent, it has a unique solution. Both dependent and independ...
