In the standard equation for an ellipse, b is half the length of the _____ axis.Answer:
Multiply by 1/2 or Divide by 2
The Chinese use a method called "multiplication grid" or "Chinese lattice multiplication". It involves creating a grid and filling it in with the digits of the multiplicand and multiplier, then multiplying each digit and summing the results diagonally to get the final product. This method is a visual and systematic way to break down and solve multiplication problems.
We write .5 or 0.5 as the decimal for one half.
As an equation: 24 = x/2
1/2x=-5

X ÷ 2 = 14 or X/2 = 14 where the / means divided by.
Division by a number is the same as multiplication by its reciprocal (or inverse). So, division by a half is the same as multiplication by 1/half or two. Thus, the answer is 432 / (1/2) = 432*2 = 864

Yes, an isotope is still radioactive after one half life. There is simple one half of it left. And there will be one half of that half, i.e. one quarter left after a second half life, and half of that half, i.e. one eight left after a third half life, etc. The equation for half-life is ... AT = A0 2(-T/H) ... where A0 is the starting activity, AT is the ending activity at some time T, and H is the half-life in units of T. Sometimes, you see this equation in other forms, such as with e instead of 2, but there is another factor in the exponent. They are all the same. This equation, with the 2, makes the meaning of half-life clear because a negative power of 2 is simply 1/2, 1/4, 1/8, etc.
No, it cannot. The product of a rational and irrational is always irrational. And half a number is equivalent to multiplication by 0.5
Not exactly sure what you mean about "aluminum's half life equation." Exponential decay, from where we get the half-life equation from, has nothing to do with mass, atomic number, etc... and therefore has nothing to do with any particular isotope.
