We have the following function:
N (k):
Where, the indepent variable is k
The dependent variable is N
For the function:
k (n):
the independent variable is n
The dependent variable is k
Thus,
N (12) = 4
k (4) = 12

Step-by-step explanation:
The value of x in the triangle is 0.21
<h3>How to determine the value of x?</h3>
The given parameters are:
mA = 90°
cos(B) = 7x - 0.55
sin (C) = x + 0.71
Since the angle is a right triangle, then
C + B = 90
In a right triangle;
If C + B = 90, then
sin(C) = cos(B)
So, we have:
7x - 0.55 = x + 0.71
Evaluate the like terms
6x = 1.26
Divide both sides by 6
x = 0.21
Hence, the value of x in the triangle is 0.21

Step-by-step explanation:
Given the equation
Putting x = -2 in the equation
y = 2x + 3
= 2(-2) + 3
= -4 + 3
= -1
(x, y) = (-2, -1)
Putting x = -1 in the equation
y = 2x + 3
= 2(-1) + 3
= -2 + 3
= 1
(x, y) = (-1, 1)
Putting x = 0 in the equation
y = 2x + 3
= 2(0) + 3
= 0 + 3
= 3
(x, y) = (0, 3)
So the table chart of x and y values will be:
x y
-2 -1
-1 1
0 3

The recursive formula of the sequence is aₙ = aₙ₋₁ - 30
<h3>How to determine the
recursive formula of the sequence?</h3>
From the question, we have the following sequence that can be used in our computation:
67 ,37 ,7, -23, -53
In the above sequence, we can see that the 30 is subtracted from the previous term to get the current term
Using the above as a guide,
So, we have the following representation
aₙ = aₙ₋₁ - 30
The above represents the recursive rule
Hence, the recursive rule of the function is aₙ = aₙ₋₁ - 30
