<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>
Answer:
3 packages
Step-by-step explanation:
each package has 3
if she buys 1, she has 3 party favors
buys 2, has 6
buys 3, has 9
she can't buy 2 packages, then one friend doesn't get a party favor. so she will have to buy 3 packages, use 7, leave 2 extra.
please give thanks :)
If you are going to claim SAS congruence, you need to show the sides on either side of the angle are congruent. One of those sides is AB; the other is AC.
Selection D is appropriate.
Answer:
x = -6
Step-by-step explanation:
Step 1 :
Pulling out like terms :
1.1 Pull out like factors :
-2x - 12 = -2 • (x + 6)
Equation at the end of step 1 :
Step 2 :
Equations which are never true :
2.1 Solve : -2 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation :
2.2 Solve : x+6 = 0
Subtract 6 from both sides of the equation :
x = -6
One solution was found :
x = -6
