How many times larger than 2x10^3 is 6x10^6?

Zielflug [23.3K]

Answer: 5,998,000

Step-by-step explanation:

2x10^3= 2,000

6x10^6= 6,000,000

In translation, Use 1 x The Initial SIG FIGS, or first numbers. 10x10 is 100, and notice how 10 and 10 have 2 zeros, so 1x1 = 1 +00 is a way to construct the number.

In this case, the 10^x, the x can represent the number of zeros after our first value.

So, 6 + six zeros, or 6,000,000

and, 2 + 3 zeros, or 2,000

To find the difference, subtract the numbers from eachother and extract the absolute value, (meaning the final answer won't be negative).

So, 6,000,000 - 2,000 = 5,998,000, which is the answer to the prompt!

Hope this Helped!

What is the lcm of 2x²and3y

zloy xaker [14]

Answer:

LCM(2x² , 3y) = 6x²y

Step-by-step explanation:

these two expressions 2x²and 3y have no common factor

Then

LCM(2x² , 3y) = 2x² × 3y

= (2×3)x²y

= 6x²y

An Archaeologist in Turkey discovers a spear head that contains 51% of its original amount of C-14. Find the age of the spear he

disa [49]

Use given half-life for C-14 of 5,730 years.

The exponential decay function:
$y = e^{-kt}$
plug in half life, solve for 'e^(-k)'
$0.5 = e^{-5730k} \\ \\ 0.5 = (e^{-k})^{5730} \\ \\ e^{-k} = (0.5)^{1/5730}$

Sub into original decay function, plug in 0.51 for 'y' and solve for 't'

$y = e^{-kt} = (e^{-k})^t \\ \\ 0.51 = (0.5)^{t/5730} \\ \\ ln(0.51) = \frac{t}{5730} ln(0.5) \\ \\ t = 5730 \frac{ln 0.51}{1n 0.5}$
