ANSWER

EXPLANATION

The given series

This is an arithmetic series with a common difference of

The first term of the series is:

The general term is given by:

The last term is 81

We can use this to determine the number of terms in the series.

The summation notation is:

45 minutes

step-by-step explanation:

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.
