Answer:
All real numbers greater than zero.
Step-by-step explanation:
Any real number greater than zero but lesser than 1 lead to a negative number. When input is 1, the output is zero. Lastly, any real number greater than 1 leads a positive number. Hence, the domain of the natural logartihmic function is the set of all real numbers greater than zero.
Answer:
the answer is: -4.0,2 I just took the test and it was right
Step-by-step explanation:
A is perpendicular to n

Answer:
I think it is 3
Step-by-step explanation:
I'm not really familiar with this formatting but I believe you are trying to make like a multiplication like table, and you need to solve for x. if the first number is 2 then the next would be 3.
Answer:
a) R(r) = kr⁴
b) R(r) = 1.5625 r⁴
c) R = 126.56 cm³/s when r = 3 cm
Step-by-step explanation:
Rate of flow of a gas through a cylindrical pipe = R
radius of the pipe = r
a) R ∝r⁴
R(r) = kr⁴ where k is the proportionality constant.
R(r) means R is a function of r.
b) R(r) = kr⁴
R = 400 cm³/s, r = 4 cm
400 = k × 4⁴
k = 400/4⁴ = 400/256 = 1.5625 (cm.s)⁻¹
R(r) = 1.5625 r⁴
c) R(r) = 1.5625 r⁴
R = ?
r = 3 cm
R = 1.5625 × 3⁴ = 126.5625 cm³/s = 126.56 cm³/s
