There are 20 parrots at the animal sanctuary. Their population is increasing at a rate of 15% per year. There are also 24 snakes
worty [1.4K]
For the answer to the questions above,
A) Parrots are following a Geometric Progression of 15% increase.

20(1.15),  20(1.15)², 20(1.15)³,

Function  = 20(1.15)^n      Where n is at the end of year, n =1, 2, 3, ..

Snakes are increasing by 4.

28, 32, 36,....

Function =  24 + 4n          n = number of end year,      n =1, 2, 3,...

<span>B) After 10 years:              </span>
Parrot =  20(1.15)¹⁰    = 80.91115471

Snakes =  24 + 4(10) = 64

<span>C) After what time they are the same: </span>
We use trial and error:


Test:  n                             20(1.15^n)                        (24 + 4n)
          1                                    23                                   28
          2                                    26.45                              32
<span>          3                                    30.41                             36    </span>
          4                                    34.98                              40
          5                                    40.23                              44
          6                                    46.26                              48
          7                                    53.20                              52
          8                                    61.18                              56
          9                                    70.36                              60

After year 7, the Parrots increases far more.
<span>At year 7 they are roughly the same.</span>

What is the value of x?<br> Enter your answer in the box.
hram777 [196]

Answer:

Both the angles are equal and opposite angles and are of 52°

Step-by-step explanation:

The two angles are equal and opposite angles.

So,

        (3x-14)°=[4(x-9)]°

         3x-14=4x-36\\\\4x-3x=36-14\\\\x=22

Putting the value of 'x', the angles are:

3(22)-14=66-14=52°

4(22-9)=4(13)=52°

Both the angles are equal and opposite angles and are of 52°
