The slope of the parallel line is -6/7
the slope of the perpendicular line is 7/6
the slope of the line = -6/7
the gradient of two parallel lines are equal
the product of the gradient of two perpendicular lines is -1
: the gradient m1*m2 = -1
m2= -1(-6/7)
m2= 7/6
Answer:
Step-by-step explanation:
The cotangent function can be rewritten by trigonometric relations, that is:
(1)
By taking approach the periodicity properties of the cosine and sine function (both functions have a period of 360°), we use the following equivalencies:
(2)
(3)
By (2) and (3) in (1), we have following expression:
If we know that 
and 
, then the result of the trigonometric expression is:
Answer:

Step-by-step explanation:
If f(x) is an even function, then
f(x) = f(- x)
f(- x) = (- x)³ + 5(- x) + 1 = - x³ - 5x + 1 ≠ x³ + 5x + 1
Thus f(x) is not an even function
-2m^4 - 6m^2 +4m +4
standard form for polynomials is written with the highest degree first followed by second highest and so on from there.
