Step-by-step explanation:
((a+b)/b − a/(a+b)) ÷ ((a+b)/a − b/(a+b))
To find the domain, remember that any denominators can't be 0.
b ≠ 0
a + b ≠ 0
a ≠ 0
(5/(a+1) − 3/(a−1) + 6/(a²−1)) × (a+1)/2
Distribute the a+1.
(5 − 3(a+1)/(a−1) + 6/(a−1)) / 2
Factor out 1/(a−1).
(5(a−1) − 3(a+1) + 6) / (2(a−1))
Simplify.
(5a − 5 − 3a − 3 + 6) / (2a−2)
(2a−2) / (2a−2)

Answer:
904.8 cm rounded (904.78 cm^3) to the nearest tenth.
Step-by-step explanation:
V= 904.8 cm rounded (904.78 cm^3) to the nearest tenth.
Step-by-step explanation:
The volume of a sphere is given as 4/3πr^3
There is only one variable, the radius, which we are given in the problem.
since the radius is 6 cm, we can plug that in to the formula
4/3π6^3
Put this into the calculator, and we see that the volume is
904.8 cm rounded (904.78 cm^3) to the nearest tenth.
Those | | means that whatever the number inside is, will always be positive so it is equal
You multiply the exponent
Remember to MULTIPLY exponents (not add them) when you are raising a power to a power. In this case, (−3x3y2)4 = (−3)4(x3)4(y2)4 = −34 · x3·4 · y2·4.
