Gaurav Seth 4 years, 10 months ago

Find the critical points, here they are 1 and 3.
solve for x<1,
-(x-1)-(-(x-3))≥0
-x+1+x-3≥0
-2≥0 (not possible)
Thus, x should be greater than 1
For 1 ≤ x ≤ 3
(x-1)-(-(x-3))≥0
2x-4≥0
x≥2
So one solution set is 2≤x≤3
For x>3
(x-1)-(x-3)≥0
2≥0
Therefore from above two results,
x≥2

Gaurav Seth 4 years, 10 months ago

Answer:

Sum = 5 + 55 + 555 + …. n terms.
= 5/9 [9 + 99 + 999 + …. n terms]
= 5/9 [(10 – 1) + (100 – 1) + (1000 – 1) + … n terms]
= 5/9 [10 + 100 + 1000 ….. – (1 + 1 + … 1)]
= 5/9 [10(10ⁿ – 1)/(10 – 1) + (1 + 1 + … n times)]
= 50/81(10ⁿ – 1) – 5n/9

Sia ? 4 years, 6 months ago

The graph of modulus function is continuous having a corner at x=0. It means that graph is differentiable at all points except at x=0 (we can not draw a tangent at a corner). Since graph is symmetric about y-axis, modulus function is even function. We also see that there are pair of x values for non-zero values of y.
