EleoNora [17]
From 2010 year to 2015 year 5 years passed, then t is equal to 5.
To find how many people attended the festival in 2015 we have to calculate y(5): 
y(5)=180,000(1.2)^{5}=180,000*2.48832=447,898
Answer: 447,898 p. attanded festival in 2015

A radioactive compound with mass of 260 grams decays at a rate of 3.8% per hour. Which equation represents how many grams of the
Dahasolnce [82]

The exponential equation that represents how many grams of the compound will remain after 8 hours is:

B: C=260(0.962)^8

<h3>What is an exponential function?</h3>

A decaying exponential function is modeled by:

A(t) = A(0)(1 - r)^t

In which:

  • A(0) is the initial value.
  • r is the decay rate, as a decimal.

A radioactive compound with mass of 260 grams decays at a rate of 3.8% per hour, hence the equation for the mass after t hours is given by:

A(t) = 260(1 - 0.038)^t

A(t) = 260(0.962)^t

After 8 hours, the amount is given by:

A(t) = 260(0.962)^8

Hence option B is correct.
