Answer: it’s 6:00 pm
Step-by-step explanation:
Answer:
Really? The pattern is that this is probably influenced by is a negative exponential function. The pattern is that the exponent is decreased by one.
Step-by-step explanation:
Take the logarithm of both sides. The base of the logarithm doesn't matter.


Drop the exponents:

Expand the right side:

Move the terms containing <em>x</em> to the left side and factor out <em>x</em> :


Solve for <em>x</em> by dividing boths ides by 5 log(4) - log(3) :

You can stop there, or continue simplifying the solution by using properties of logarithms:



You can condense the solution further using the change-of-base identity,

Answer:
