A park started with 12 oak trees, and the number of oak trees increased at a rate of 25% each year. Write the function that mode
Helen [10]

Answer:

The function which models the situation is as The number of oak trees increase after n year = 12 ×  (1+\frac{25}{100})^{n}

Step-by-step explanation:

Given as :

The number of oak trees planted in park = 12

The rate at which number of tree increase each year= 25%

Now,

The number of oak trees increase after n year = Present numbers of tree × (1+\frac{Rate}{100})^{n}

Or,

The number of oak trees increase after n year = 12 × (1+\frac{25}{100})^{n}

Hence The function which models the situation is as The number of oak trees increase after n year = 12 × (1+\frac{25}{100})^{n}  Answer
