Answer:
Step-by-step explanation:
If a point (x, y) lies on a straight line, coordinates of the point will satisfy the equation.
Slope of a line passing through two points C(4, 5) and D(8, 10),
m = 
m = 
m = 
Equation of the line passing through C(4, 5) and slope m =
y - y' = m(x - x')
y - 5 = 
y = 
y = 
If point B(4, 0) lies on the line CD,
0 = 
0 = 5
Which is not true.
Therefore, point B doesn't lie on line CD.
The cotangent function is defined as the ratio between cosine and sine of a given angle, i.e.
Since you can't have zero at the denominator, the cotangent function is not defined when the sine is zero.
Let's look at your option:
, so the cotangent is defined here
, so the cotangent is not defined here
, so the cotangent is defined here
, so the cotangent is defined here
Assuming that all tiles must stay whole it would be:
1×54
2×27
3×18
6×9
If the number is 5 or greater you round it up
if its four or less you round down
0 bcz modulas function every negative no. in positive
therefore it becomes 6 - 6 I.e equal to 0
