Acomputer is programmed to scan the digits of the counting numbers. for example, if it scans 1 2 3 4 5 6 7 8 9 10 11 12 13 then it has scanned 17 digits altogether. if the computer begins its task and scans the first 1392 digits starting at 1, what is the last counting number scanned?

I believed it is "401"

1-9 = 9 digits

10-99 = 90 which is 180

100-200 = 100 which is 300 digits

9+180= 189

1392-189= 1203

1200÷300=400 which 1200 digits

401 is the 1392 number scanned

p(x)= 8 x³ - 36 x² + 54 x - 27

q(x) = 2 x -3

you can check your mistake and then you can choose the correct option.

dividend =   8 x³ - 36 x² + 54 x - 27

divisor = 2 x -3

if you want to find quotient, proceed as follows

q(x)= 0

2 x - 3=0

x =

now , i have used division method , to find quotient and remainder

b and c are the correct answers.

good luck on the quiz! : d
