Given :
A line 2x + 1 =0 .
To Find :
The slope of the given line .
Solution :
We know , slope of line is given by the tangent of the angle between the x-axis and the line .
Now, for line 2x + 1 =0 i.e 
.
The line is perpendicular to x-axis and cuts the x-axis at 
.
Therefore , the angle between the line and x-axis is 
.
So , slope 
i.e undefined .
Therefore , the slope of given line is not defined .
Hence , this is the required solution .
The drawbridge will be at an incline of 10.56 degrees. That is 5.56 degrees more than it's initial incline of 5 degrees.
If you draw a picture of this situation, you will see that you can write a sine ratio with the 11 and 60 (opposite over hypotenuse)
sin(x) = 11/60 Solve the equation for x
x = 10.56
Answer:
1.9x10^-2
hope this helps
Step-by-step explanation:
D. 7
e. 4
f. 5
g. 11
Get these by adding/subtracting the number at the end (use the opposite operation) and then divide the coefficient from both sides.
