Answer:
4 feet
Step-by-step explanation:
4/3 times 15 is 20, 4/3 times 3 is 4
4, 7, 12, 19, 28
1st difference +3 +5 +7 +9
2nd difference +2 +2 +2
This is a geometric sequence
The form is:
an² + bn + c
2a is always = to the second difference
2a = 2
a = 1
3a + b = 2nd term - 1st term
3(1) + b = 3
3 + b = 3
b = 0
a + b + c = 1st term
1 + 0 + c = 4
1 +c = 4
c = 3
nth term of sequence {substitute all we have found}
1n² + 0 + 3
n² + 3
Add 11.7 and 2. The answer is 13.7 (quarts).
The answer is 2268pi ft^3
