D. the perimeter of a regular n-gob is the area divided by the all them.
Answer:
x = 2k
is the solution of this equation.
Step-by-step explanation:
This question is related to trigonometric equations.
The given equation is,

We have to find the solutions of this equation.
Put 
+ 3cosx - 1 = 2
= 0
For this equation only cosx = 1 is possible solution.
Cosx = 1 happens when x is a multiple of 2
So x = 2k
is the solution of this equation.

Step-by-step explanation:
The distance between both lines is 2.24 units
Step-by-step explanation:
There is no straight method to find the distance between two lines. The distance can be found out by finding a point on one line and then finding the distance of that point from the other line. The y-coordinate of point is obtained by putting any value of x in equation . The x and y combined give us the point.
Given

We have to find the distance of this point from y=2x+5

The formula for finding distance of a point (x,y) from a line is:

A=2
B=-1
C=5
Putting the values in the formula

Rounding off will give: 2.24 units
The distance between both lines is 2.24 units
