not including the widht of each pole, Check the picture below.
Answer:
y=6x-2 is perpendicular to the 6y=-x+7
y=6x+1 is parallel to the y=6x-2
Step-by-step explanation:
if product of two lines gradient is -1 than lines are perpendicular
gr y=6x-2
y=mx+c m=gradient
1)m=6
2)m=-1/6
3)m=6
if gradients of 2 lines are equal they are paralel
Answer:
Option d is correct.
Step-by-step explanation:
The point of inflection of a function y = f(x) at a pointy c is given by f''(c) = 0.
Now, the given function is

Differentiating with respect to x on both sides we get,

Again, differentiating with respect to x on both sides we get,

So, the condition for point of inflection at point c is
k''(c) = 0 = - sin c + 2 sin c cos c
⇒ sin c(2cos c - 1) = 0
⇒ sin c = 0 or 
⇒ c = 0 or
Therefore, option d is correct. (Answer)
