Answer:
See below
Step-by-step explanation:
The function 
oscillates between -1 and 1, so the range is 
.
Ayanna is 17 and Brittany is 14.
To find this, let's write two equations using the given information.
a = b + 3
3b + 2a = 76
Now, just substitute the first equation into the second and solve.
3b + 2(b + 3) = 76
3b + 2b + 6 = 76
5b = 70
b = 14
If Brittany is 14, then Ayanna is 3 years older at 17.
Area = πr^2
π4^2 =16π
