(x^2 + 4)^2. and - (x^2 + 4)^2
Prime factors: 99999 = 3^2*41*271
This pattern could also be represented by:
a(n) = (1/2)(n-1)^3 - (3/2)(n-1)^2 + 4(n-1) + 2
in which case a(41) = 29766
In general there are an infinite number of ways of representing these simple series!
The surface area of the curved part of a cylinder is given by pi*diameter*height
Unfortunately, there is no store on the calculator on the home page here.
5.3*10^-5
As follows:
.
The range will be given by the difference between the square root of the largest number and that of the smallest number.
The probability is given by p = nCr(5,2)*(1*1*6*5*4)/(12*11*10*9*8) → 10*1/792 → 5/396 ≈ 0.013
Not on the calculator, but LaTeX is available on the question/answer edit page:
