Although the actual amount varies by season and time of day, the average volume of water that flows over the falls each second

lutik1710 [3]

Given that <span>the average volume of water that flows over the falls each second is $4.8 \times 10^5$ gallons.

There are 3,600 seconds in one hour.

Thus, in one hour, $4.8 \times 10^5\times3600=17280\times10^5=1.728\times10^9$ gallons of water </span><span>flows over the falls.

</span>Therefore, the amount of water that flows over the falls is <span> $1.728\times10^9$ .</span>

Use the properties of logarithms to prove log, 1000 = log2 10.

Leto [7]

Given:

Consider the equation is:

$\log_81000=\log_210$

To prove:

$\log_81000=\log_210$ by using the properties of logarithms.

Solution:

We have,

$\log_81000=\log_210$

Taking left hand side (LHS), we get

$LHS=\log_81000$

$LHS=\dfrac{\log 1000}{\log 8}$ $\left[\because \log_ab=\dfrac{\log_x a}{\log_x b}\right]$

$LHS=\dfrac{\log (10)^3}{\log 2^3}$

$LHS=\dfrac{3\log 10}{3\log 2}$ $[\because \log x^n=n\log x]$

$LHS=\dfrac{\log 10}{\log 2}$

$LHS=\log_210$ $\left[\because \log_ab=\dfrac{\log_x a}{\log_x b}\right]$

$LHS=RHS$

Hence proved.
