A) can be done using u-substitution .... Let u = x^2, du = 2x dx
C) can be done using trig identity ... cos(2x) = 1 - 2sin^2
B) can only be done using integration by parts. It is a product of 2 distinct functions and a u-sub does not simplify the integral.
Answer:
(0,6) is the answer.................
Answer:
Recall that gas will always take the shape and volume of its container.
Volume of sphere or gas = 4/3.πR³ = 4π/3 x 0.521³, V = 0.59 m³
Density of the gas, D = mass / volume = 107kg / 0.59m³ , D = 180.60 kg/m³
The density of the compressed gas = 180.60 kg/m³
I would say A but I’m not sure
