Answer:
Step-by-step explanation:
Add 1 and subtract 1, so that the expression won't change.
(a² - b²) = (a+b)(a - b)
Here a = x² - (1/x²) and b = 1
![= [ (x^{2}-\frac{1}{x^{2}})+ 1 ] [ (x^{2} -\frac{1}{x^{2}} - 1 ]](https://tex.z-dn.net/?f=%3D%20%5B%20%28x%5E%7B2%7D-%5Cfrac%7B1%7D%7Bx%5E%7B2%7D%7D%29%2B%201%20%5D%20%5B%20%28x%5E%7B2%7D%20-%5Cfrac%7B1%7D%7Bx%5E%7B2%7D%7D%20-%201%20%5D)
Answer: sincostan triggy
Step-by-step explanation:
Segment AB is a diameter of the sphere.
diameter = AB = 16 in.
radius = r = (16 in.)/2 = 8 in.
Volume of a sphere:
V = (4/3) * pi * r^3
V = (4/3) * (22/7) * (8 in.)^3
The water inside the bowl occupies half of the bowl, so the volume of the water is half the volume of the bowl.
Volume of water:
V = (1/2)(4/3)(22/7)(8^3) in.^3
Answer: Second choice.
Hello from MrBillDoesMath!
Answer:
The correct answer is p >= -5/3
but I don't see that answer as a provided choice (?)
Discussion:
Solve:
2(6p-5) >= 3(p-8) - 1 =>
2*6p - 2*5 >= 3*p - 3*8 -1 =>
12p -10 >= 3p - 24 - 1 => (subtract 3p from both sides)
12p-3p - 10 >= -25 => (add 10 to both sides)
9p >= -25 + 10 = -15 =>
p >= -15/9 = -5/3

MrB
