Round 9,614,018,007 to the nearest ten million.

  1. We are rounding to the nearest ten million.
    9,614,018,007, with the first 1 labeled, ten millions position.
  2. Observe the digit immediately to the right of the ten millions position. It is 4. Since 4 is less than 5, we round down by replacing 4 and all the digits to its right with zeros.
    9,610,000,000

Thus, 9,614,018,007 rounded to the nearest ten million is 9,610,000,000.

Round 148,422 to the nearest million.

  1. Since we are rounding to the nearest million, we'll have to imagine a digit in the millions position. We'll write 148,422 as 0,148,422.
    0,148,422, with the 0 labeled, millions position.
  2. The digit immediately to the right is 1. Since 1 is less than 5, we'll round down by replacing it and all the digits to its right with zeros.
    0,000,000
    This number is 0.

Thus, 148,422 rounded to the nearest million is 0.

Round 397,000 to the nearest ten thousand.

  1. We are rounding to the nearest ten thousand.
    397,000, with the 9 labeled, ten thousand position.
  2. The digit immediately to the right of the ten thousand position is 7. Since 7 is greater than 5, we round up by replacing 7 and all the digits to its right with zeros and adding 1 to the digit in the ten thousands position. But 9 + 1 = 10 and we must carry the 1 to the next (the hundred thousands) position.
    400,000

Thus, 397,000 rounded to the nearest ten thousand is 400,000.

20/(×-6^2)
Salomon
okay, so you have 6 raised to the power of 2. what is that part of your answer
ninjadapaul
I don't understand what the A with approx sign and the boxed x mean
ninjadapaul
it think it's written 20/(X-6)^2 so it's 20 divided by X-6 squared
Salomon
I'm not sure why it wrote it the other way
Salomon
I got X =-6
Salomon
ok. so take the square root of both sides, now you have plus or minus the square root of 20= x-6
ninjadapaul
oops. ignore that.
ninjadapaul
so you not have an equal sign anywhere in the original equation?

hmm

The answer is neither. The function, 2 = 0 cannot exist. Hence, the function is undefined.

Prasenjit Reply
At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.
