Answer:
D) 132
Step-by-step explanation:
y + 3x = 180 {Co interior angles}
y = 180 - 3x ------------(I)
7x + 20 = y {Vertically opposite angles}
7x + 20 = 180 - 3x {From equation (I)}
7x + 3x +20 = 180
10x + 20 = 180
10x = 180 -20
10x = 160
x = 160/10
x = 16
Plug in x = 16 in equation (I)
y = 180 - 3x
= 180 - 3*16
= 180 - 48
y = 132
Taken that y don't have f(sin, cos)
you aren't looking for fourier solution or midline like in AC voltage calculation and rather bulk median ?
amplitude can be found by derivating and zero points, but it has been years
The crucial point in this problem is the amount of the data usage. Since it's not given by reasoning with math logic we can find the correct answer. Let's find that if we spend 5$ in the first case, how much amount of data we would be able to use. By setting
0.002$_______1 KB
5$_______x and x=2500 KB or 2.5 MB
From this fact, we can yield that if you are willing to use more than 2.5 MB of data, it is mathematically correct to choose the second option since in this case you will save money.
Because of the Absolute Values, when x = -1 or -2, the overall range
is [-1, co)
