C. y= [25,100]
you need brackets because the points actually touch the number
Answer:
5 1/6
Step-by-step explanation:
Note that - ( -7 1/3) = 7 1/3. The two ' - ' signs cancel each other.
Thus, the original expression becomes -2 1/6 + 7 1/3.
Here the LCD is 6. We re-write the above expression as -2 1/6 + 7 2/6.
Reversing the order of these terms makes the work a bit easier.
7 2/6 - 2 1/6 comes out to 5 1/6
For cosФ×sinФ =0, then either cosФ or sin Ф must be zero.
cos 90 = cos 270 = 0
sin 0 = sin 180 = sin 360 = 0.
So, the values that would give you 0 are:
1. cos 90 sin Ф
2. cos 270sin Ф
3. cos Ф sin 0
4. cos Ф sin 180 and
5 cos Ф sin 360.
