<span>Part A. Functions. Parrots: it is a geometric progression: first year, 20 parrots; second year, 20 * 1.15; third year 20 * 1.15^2, fourth year, 20*1.15^3 => P(n) = 20 (1.15) ^ (n -1). Snakes: it is an arithmetic progression: first year, 24 snakes; second year, 24 + 4 snake; third year, 24 * 4(2) => S(n) = 20 + 4(n-1). Part B. Parrots after 10 years = P(10) = 20(1.15)^9 = 70 Parrots. Snakes after 10 years = S(10) = 20 + 4 (10-1) = 56.</span>
if they had spend 1500 total for goods and expenses 500 which is total 2000 and
revenue is 3000
1500 + 500 - 3000 = 1000 is profit for the business
Answer: B. |x-100| = 25
Explanation:
Draw out a number line. Mark 75, 100 and 125 on the number line as points A, B, and C in that order. Don't worry about the spacing.
The value of x represents where the train is. So if we had say x = 85, then it would be at location 85 on the number line. Writing |x-100| is the distance from x to 100. The absolute value ensures the distance is never negative. We want this distance to be 25 because after traveling 25 cm, the switch is turned, and the train goes the other way.
