The x intercept means that F(x) = 0
sin(4x)/2x=0
Which means that sin 4x=0
4x E {(-1)^n arcsin 0 +npi | nE Z}
x E {npi/4}
For x between 0 and pi means that x E {0, pi/4, pi/2, 3pi/4, pi}.

Answer:
18
Step-by-step explanation:
1) 90 --- 100%
x --- 20%
x = 90*20/100 = 18
2)
20 % = 20/100 = 0.2
20 percent (0.2) of (*) 90 = 0.2*90 = 18
Take the tax (6$) and divide it by the pretax(75$) and take that number and multiply it by 100 and you get your percentage (8%)
The answer is tenth. It goes tenth, hundredth, thousandth... Etc.
