Can anyone find the length of AO?
nika2105 [10]

Hello from MrBillDoesMath!

Answer:   2


Description. Create a line from point A perpendicular to the x axis. This line, with the radius (OA) , and x axis, form a right triangle. By Pythagoras,

     x-length             y-length                         hypotenuse squared

  ( 3 ^ (1/2) ) ^ 2    +  1 ^ 2             =  3 + 1    = 4


So, the square of the hypotenuse (or radius OA in this case) is 4. That means OA is the square root of 4 or 2.


Regards, MrB

REY [17]

The number of marriage licenses were issued in 2003 is 21586.

According to the statement

we have to find the number of marriage licenses were issued in 2003

and the given equation is y=3.405x^2-17674x+21533000

And in this equation x represent the time

And Y represent the number of marriage certificate issued.

So, in given equation

y=3.405x^2-17674x+21533000

we fill the value of X and find the value of Y means tne number of marriage license is issued in 2003

We know that X = 3 from 2000 to 2003

Then put X=3 in the given equation.

Then

This is the equation (1) represent the change

y=3.405(3)^2-17674(3)+21533000 -(1)

y = 30.645+53022+21533000

y = 21586052.645

On nearest hundred the value becomes 21586.

So, The number of marriage licenses were issued in 2003 is 21586.
