A radioactive isotope is decaying at a rate of 15% every hour. Currently there are 150 grams of the substance. Write an equation that will represent the number of grams present after n hours. How much will be left one day from now?A radioactive isotope is decaying at a rate of 15% every hour. Currently there are 150 grams of the substance.

The equation that will represent the number of grams present after n hours is

3.035 grams will be left one day from now.

Step-by-step explanation:

Exponential equation for the amount of a substance:

The exponential equation for the amount of a substance is given by:

In which A(0) is the initial amount and r is the decay rate, as a decimal, and t is the time period.

A radioactive isotope is decaying at a rate of 15% every hour.

This means that

Currently there are 150 grams of the substance.

This means that

Write an equation that will represent the number of grams present after n hours.

How much will be left one day from now?

One day is 24 hours, so this is A(24).

3.035 grams will be left one day from now.

the nearest power is 1.651.

means 7482 to the 1.651th power is almost equal to 2489287
