How to write 1,948,447 in a expanded notation

Answer:

Intersection points (1,2) and (-3,-6)

The y-coordinates of the points of intersection from smallest to largest is -6 to 2.

Step-by-step explanation:

Given : A system of equations and  

To find : Write the y-coordinates of the points of intersection?

Solution :  

Let,

and  

Now, we plot these two equations.

The graph of  is shown with red line.

The graph of  is shown with blue line.

The solution to this system will be their intersection point.

The intersection points of these graph are (1,2) and (-3,-6).

Refer the attached graph below.

Therefore, The y-coordinates of the points of intersection from smallest to largest is -6 to 2.

Answer:

The radius of circle is 4

Step-by-step explanation:

Given as :

The equation of circle is given as :

x² + y² = 16

Now The standard equation of

( x - h )² + ( y - k )² = r²

where h , k are center of circle

         r is the radius of circle

From given circle equation x² + y² = 16    can be written as

     ( x - 0 )² + ( y - 0 )² = (4)²

So, The center of this circle is ( h , k ) = ( 0 , 0 )  And radius of circle = 4

Hence The radius of circle is 4    Answer

Answer:

C 4

Step-by-step explanation:

well 4x2 + 4x2 = 16

and radius is 1/2 of diameter so 1/2 of 8 is 4

There are 4 quarts in one gallon:

1 gal = 4 qt

Then, we want to find the number of quarts in 19 gallons. We can write a proportion:

1/4 = 19/x

Cross multiply:

x = 76 quarts.

There are 76 quarts in 19 gallons.

76 quarts in 19 gallons
