Question 1 2 Points 1 \\*-2 Chickens have the greatest population What is the value of x in the expression =5*+107 125 among the species of birds because they are used as poultry. Further, they are one of the basic sources of food for humans. Now, suppose there are O 40 billion chickens in 2014, and they continue to increase exponentially (at every instant) at a rate of 23% every year. If 77% of the population are consumed by humans every year, how -1 many chickens will there be at the start of the year 2024. A) 73 billion chickens -6 72 billion chickens 25 billion chickens 92 billion chickens D The growth of a certain savings account is described by the table below: A laboratory test confirms that 9 milligrams of a particular radioactive substance t (years) 0 1 2 decreases to 7 milligrams in 20 seconds. Determine the half - life of the substance. S(t) (amount int $3200 $3280 $3362 $3446.06 years) D 10.25 seconds Find the formula that describes the growth of this savings account. B 55.16 seconds A S(t) = 3200(1 + .069) C 40 seconds B S(t) = 4200(1 + .044) D 32.27 seconds C S(t) = 3200(1 +.025) D S(t) = 3200(1 + .042)
