In 2008, there were 6.7 * 10^9 people living on earth. what is that number in standard
notation?

6,700,000,000

Step-by-step explanation:

Standard Notation is the normal way of writing numbers.

Scientific notation of 6.7 * 10^9  would mean we need to move the decimal point "9" units "to the right" and arrive at our normal standard form of the number.

So, we move 1 decimal place and create 67. Then with the next 8 moves (to the right), we add 8 more zeros, so the number actually becomes:

6,700,000,000

This is 6 billion, 700 million.

This is the normal standard way (standard notation) of writing numbers.

2 x^2 -3x+p

sum of roots = 3/2

let other root be x

3+ x = 3/2

x= 3/2 - 3 = -3/2

product of roots = p/2

3× -3/2 = p/2

-9 = p

⭐⭐

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
