C is not a linear function
Answer:
1/2
Step-by-step explanation:
Let's pick two points and find the slope inbetween them.
I'll pick (2,1) and (0,0).
Remember that slope = change in y / change in x.
slope = 1-0 / 2-0 = 1/2
Replace a and b with the given values:
3.14(3^2 + 3x4)
Simplify:
3.14(9 +12)
3.14(21)
Multiply:
3.14 x 21 =65.94
Answer:
Step-by-step explanation:
Remark
This is actually a six sided figure. That really doesn't matter, but it's interesting to observe. It goes a long way to explaining what is going on. The trick to exterior angles is that as long as the figure is convex ( a closed figure whose lines do not cross), the exterior angles add to 360.
Once you know that, then you know that this figure must have 6 exterior angles and no matter how they are made, their total is 360.
Equation
n + n + n + n + 90 + 90 = 360 Combine like terms.
Solution
4n + 180 = 360 Subtract 180
4n = 360 - 180
4n = 180 Divide both sides by 4
4n/4 = 180/4
n = 45

Not a simple problem. Thanks for posting
Answer:
B) 112°
Step-by-step explanation:
After the double reflection the point is effectively rotated by an amount that is double the angle between the lines of reflection:
2·56° = 112°
_____
In the attached, lines l and m are separated by 56°, as required by the problem statement.
