Answer:
-2
Step-by-step explanation:
12=4<u>-4</u><u>x</u>
<u>4</u><u>x</u>=4-12
<u>4</u><u>x</u><u>=</u>-8 /:4
<h2>
<em><u>x</u></em><em><u>=</u></em><em><u>-</u></em><em><u>2</u></em></h2>
P= 3000 (1.21)^t, t= time in months
1 year = 12 months, and therefore, 1 month = 1/12 years
The equation showing yearly population growth changes to;
P=3000 (1.21)^t/12
The correct answer is equation [1].
3 divided by 64 is 0.046875
