An arithmetic sequence is that in which the consecutive terms share or have the same difference commonly referred to as the "common difference". The terms in the arithmetic sequence always starts with the term 0 or the initial value. In this item, the value of n should be greater than or equal to. Therefore the answer is the second choice. 

If we are to get the first term of the arithmetic sequence, it will become,
                     first term:
           a0 = (-1) + 7(0 - 1) = -8

Therefore, the first term is equal to -8.

Answer:

  17 -4i

Step-by-step explanation:

You do this the same way you would if i were a variable.

  8-(-4+5i)-(-5-i) = 8 +4 -5i +5 +i = (8 +4 +5) +(-5i +i) = 17 -4i

H(x)= (x^2 -36)/x +6 explain why the following function is not continuous at x=-6
sergeinik [125]

You can solve this problem through factoring.

First, you have the equation,

h(x) = \frac{x^2-36}{x-6}

Then, you can factor the numerator.

h(x) = \frac{(x+6)(x-6)}{x-6}

You can cancel out the x-6 in both the numerator and the denominator because they would equal to just 1.

You are left with h(x) = x+6

The function is removable noncontinuous at x=6 because if you plug in 6 in x-6, your denominator would be undefined.

If ADAB ACBA,<br> ZD = 132° and ZC = x + 18
d1i1m1o1n [39]

Answer:

x = 114

Step-by-step explanation:

since the triangles are congruent then corresponding angles are congruent, then

∠ C = ∠ D , that is

x + 18 = 132 ( subtract 18 from both sides )

x = 114
