Hope it helps have a good night :)))))))))))))))))
The given function is
f(x) = x⁵ ln(x)
Note that ln(x) is undefined as a real function for x ≤ 0.
Therefore the domain of the function is
0 < x <∞, or x = (0,∞).
Answer: x = (0, ∞) or 0 < x < ∞
33 times 24 is 792. There would be 792 apartments.
Answer:
16/81
Step-by-step explanation:
Given the expression, 81y'' = -16y where y = coskt,
We want to know the value of k that satisfies the expression
y' = -ksinkt
y" = -k²coskt
Substitute y and y" into the expression given;
81y'' = -16y
81(-k²coskt) = -16(kcoskt)
-81k = -16
Divide both sides by -81
-81k/-81 = -16/-81
k = 16/81
Hence the value of k is 16/81
