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

Evan went to the park and saw four animals.
dsp73

Answer:

He saw <u>1 duck</u> and <u>3 dogs</u>.

Step-by-step explanation:

Given:

Evan went to the park and saw four animals.

Each animal was either a duck or a dog.

He saw a total of 14 legs.

Now, to find the number of each animal he had seen.

Let the number of duck be x.

And the number of dog be y.

So, total number of animals:

x+y=4\\y=4-x

Now, the total number of legs he did see:

<em>As we know the legs of a duck are 2 and a dog are 4.</em>

2x+4y=14\\2x+4(4-x)=14\\2x+16-4x=14\\-2x+16=14

Adding both sides by -16 we get:

-2x=-2

Dividing both sides by -2 we get:

x=1

The number of duck = 1.

Now, putting the value of x in above equation we get:

y=4-x

y=4-1\\y=3.

The number of dogs = 3.

Therefore, he saw 1 duck and 3 dogs.
