Answer:
0.79 ft ≈ For 30 feet
Step-by-step explanation:
This is even a tricky question for me, I am pretty sure this would be around 0.79 feet. But I am not too sure so I am very sorry if I am incorrect.
I hope this helps, if it doesn't then just message me and ill be more than happy to help :)
Answer:
two real, unequal roots
Step-by-step explanation:
This is a quadratic equation. The quadratic formula can be used to determine how many and what kind of roots may exist:
Find the discriminant, which is defined as b^2 - 4ac, if ax^2 + bx + c = 0. In this case, a = 1, b = -2 and c = -8, so that the discriminant value is
(-2)^2 - 4(1)(-8), or 4 + 32 = 36.
Because the discriminant is real and positive, we know for certain that we have two real, unequal roots
0.45 Isn't Equal To Any Of These Fractions But It Is Equal To 45/100
Circumference = 2 x radius x Pi
Circumference = 2 x 0.8 x pi
Circumference = 1.6pi or 5.024 yards
area = r^2 x pi
Area = 0.8^2 x pi
Area = 0.64pi or 2.0096 square yards
