Answer:
1.
a = 1 b = 3 c = 11
2.
a = 1 b = -7 c = -11
3.
a = 1 b = 4 c = -9
4.
a = 3 b = -1 c = 16
5.
a = 1 b = 0 c = -9
6.
a = 2 b = 5 c = 0
7.
a = -4 b = 0 c = -3
8.
a = 6 b = 0 c = 0
9.
a = -1 b = 1 c = 0
Hope this helps took me a long time to type
Answer:
55.95 ft²
Step-by-step explanation:
Circumference formula: C = 2πr => r = C / (2π)
Area formula: A = πr²
Substituting C / (2π) for r in the above equation, we get:
C 47 ft
A = π( ----------- )² = π ( -------------- )²
2π (2π)
or ...
π(47 ft)² 2209 ft²
A = ---------------------- = -------------------- = 55.95 ft²
4π² 4(3.14159)²
The answer is: 12.8 F
The solution: -10.6+14.2+11-1.8
Answer: 17
Step-by-step explanation: ok so first to find the mean you add all the numbers then divide by how many numbers there is so basically 18 plus 15 plus 20 plus 15 then divide by 4 because there is 4 numbers and once you do that it is 17
