Given the arithmetic sequence an=4-4(n-1), what is the domain for n?
m_a_m_a [10]

The domain for n is  -\infty

Explanation:

The arithmetic sequence is    

To determine the domain of the sequence, let us consider  a_n as  f(n)  

Thus, the sequence becomes,  f(n)=4-4(n-1)  

The domain of the function is the set of all x-values for which the function is real and well defined.

Since, the function has no domain constraints or undefined points. Therefore, the domain of the function is

Thus, the domain of the arithmetic sequence  a_n=4-4(n-1) is  -\infty

18. Given the following four lines, pick the true statement.
Sav [38]

Answer:

Lines 2 and 4 are perpendicular

Step-by-step explanation:

Line 2: 4y=3x-4

y=3/4x - 1

Line 4: 4x+3y=-6

3y=-6-4x

y=-2 - 4/3x

The two lines are perpendicular since -4/3= - (inverse of 3/4)
