If there is 5/6 left and he plans to eat 1/6 you do 5/6-1/6=4/6 of the pie
Circumference = (pi) x (diameter) = 30 pi inches.
1 foot = 12 inches
1 mile = 5,280 feet = 63,360 inches
Number of revolutions in 1 mile = (63,360) / (30 pi) = <u>672.27...</u> revs (rounded)
Answer:
x = -6√3 or 4√3
Step-by-step explanation:
x² + 2√3 x − 72 = 0
Solve with quadratic formula, or completing the square.
To use completing the square, we first add 72 to both sides:
x² + 2√3 x = 72
Take half of 2√3, square it, then add to both sides.
x² + 2√3 + 3 = 75
Factor the perfect square:
(x + √3)² = 75
Solve for x:
x + √3 = ±√75
x + √3 = ±5√3
x = -√3 ± 5√3
x = -6√3 or 4√3
According to Vieta formula, the sum of the roots should equal b/a, and the product of the roots should equal c/a.
-6√3 + 4√3 = 2√3
-6√3 × 4√3 = -72
