Im supposed to solve this equation using logarithms but I don't know how.

Given:

To find:

The solution of the given equation.

Solution:

We have,

It can be written as

Taking log on both sides.

Putting values of logarithms, we get

Divide both sides by -0.097.

Therefore, the value of x is -2.289.

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.

you should go to the second answerthey explain it very well, give me a like
