Solving Exponential and Logarithmic Equations In Exercise, solve for x. In x = 3

Mathematics
1 answer:
mixer [17]3 years ago
7 0

Answer:

The solution is:

x = e^{3} = 20.09

Step-by-step explanation:

The first step to solve this equation is placing everything with the logarithmicto one side of the equality, and everything without the exponential to the other side. So

\ln{x} = 3

It already is in the desired format.

Now, we have that, since e and ln are inverse operations

e^{\ln{a}} = a

So, we apply the exponential to both sides of the equality

e^{\ln{x}} = e^{3}

x = e^{3} = 20.09

sveticcg [70]

Answer:

The maximum amount of the unauthorized purchases he is he liable for is: $50.

Step-by-step explanation:

Andre realizes that someone else has been using the card and reports it stolen.

So, the maximum amount of the unauthorized purchases he is he liable for is: $50.

There is a provision under the Truth in Lending Act, that if your card is stolen and any charges are incurred on it, and you report this to the card company, then you do not have to pay for that.

The most one will have to pay for unauthorized charges is $50, even if there is hundreds of dollars of bill.
