If you write down all the numbers from 1 to 500 what will be the 1000th digit that you write? ?

Step-by-step explanation:

The numbers 1 to 9 are 9 digits

The numbers 10 to 99 are 90*2 = 180 digits.

You have written 189 digits and must write another 1000 - 189 = 811 digits.

Every number from 100 to 500 have 3 digits.

811/3 = 270 1/3

So you write 270 numbers: 100 to 369

And then you will write the first number from 370 (the 1000th digit). This digit is 3.

Y and x are not constants, so you don’t have to find the value of them.

On the other hand, you do have to find m and b. M is the slope and B is where the y-axis is crossed, or what her balance was at week 0.

To find slope: (y1-y2)/(x1-x2) or the rise over run.
130-280= -150
2-8= -6
-150/-6= 25= m
This means she adds $25 each week.

To find the y-intercept: this is where x=0 and y is some unknown value. We are given the amount at the end of 2 weeks, so we just need to go back 2 weeks. She adds $25 each week. -2 weeks • 25 = -$50
130-50= 80 = b, or the initial amount in the account.

We need to plug b and m into the equation.
y=25x+80
