Gala2k [10]

Answer:

y = 30(2)^x

Step-by-step explanation:

Initial deer population = 30 (in 2010)

Every year, deer population doubles ; this means there is an 100% increase in the population every year ;

Hence, using the exponential growth relation :

Final = initial * (1 + rate)^year

Here,

Final population y ; x years after 2010

Rate = 100% = 1

Hence,

y = 30(1 + 1)^x

y = 30(2)^x

Find X and Y. can someone please help me with this question, thank you
Arturiano [62]

3<em>x</em> + 120° + <em>x</em> + 120° = 360°

4<em>x</em> + 240° = 360°

4<em>x</em> = 120°

<em>x</em> = 30°

<em>y</em> = 1/2 (3<em>x</em> - <em>x</em>)

<em>y</em> = 1/2 (90° - 30°)

<em>y</em> = 1/2 × 60°

<em>y</em> = 30°
