Anyone know the answer to this algebra 2 question?

The answer to your question is: I(dB) = 320

Step-by-step explanation:

Data

I(dB) = 10log()

I = intensity of a given sound

Io = hearing intensity

if I = 10³²(Io) find I(dB)

Process

Substitute the value of I in the equation given and simplify using logarithms rules.

                     l(dB) =

Eliminate Io

                    I(dB) = 10 log (10³²)

Use the rule of powers in logarithms

                   I(dB) = 10(32)log(10)

                   l(dB) = 320(1)

                   I(dB) = 320                

-18

step-by-step explanation:

because mean value defines that total sum value over total number of set

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.
