Answer:
28.26ft
Step-by-step explanation:
A=πr^2
π*3^2=28.27433
28.26
The answer would be 78 because 10% of 60 is 6. 6 x 3 = 18 60+18=78
Discriminant = b^2 - 4ac, where a, b and c come from the form of the quadratic equation as ax^2 + bx + c
Discriminant = (4)^2 - 4(1)(5)
= 16 - 20
= -4
-4 < 0, therefor there are no roots
(If the discriminant = 0, then there is one root
If the discriminant > 0, there are two roots, and if it is a perfect square (eg. 4, 9, 16, etc.) then there are two rational roots
If the discriminant < 0, there are no roots)
Your answer is x² + 2x + 1
