Answer:
None of the above
Step-by-step explanation:
According to the divergence test, if the limit of a sequence as n approaches infinity does not equal 0, then the series diverges. (Notice that if the limit does equal 0, the series doesn't necessarily converge).
According to the geometric series test, a geometric series converges if -1 < r < 1, and diverges otherwise.
The first series is a geometric series with r = -5/3. So it diverges.
The second series is also a geometric series:
3ⁿ⁻¹ / 2ⁿ = ⅓ (3ⁿ / 2ⁿ) = ⅓ (3/2)ⁿ
r = 3/2, so it diverges.
For the third series, the limit as n approaches infinity equals 1. This fails the divergence test, so this series also diverges.
For the fourth series, the limit as n approaches infinity equals 1. This fails the divergence test, so this series also diverges.
Answer:hello :
let : y = f(x)
you have : y = x² + 5
calculate : x
x² = y - 5
x exsit for : y - 5 ≥ 0
if : x ≥ 0 x = √( y - 5) so the inverse functio for f is : g(x) = √( x - 5)
if : x ≤ 0 x = - √( y - 5) so the inverse functio for f is :h(x) = - √( x - 5)
Answer: it is not a function if the x repeats
Step-by-step explanation: My teacher always says THE X DOES NOT REPEAT that is the easiest way to remember it
Answer:
V=785.4
Step-by-step explanation:
V=pi*r^2*h
V=pi*5^2*10
V=pi*25*10
V=pi250
V=785.39=785.4
