Answer:

$4.40

Step-by-step explanation: First you divide 73.20 by 6 to get 12.2. Thats how much each costs with tax. Then you have to take tax off so 12.2-7.80=4.4. So $4.40.

The equation x ^ 2 - 2x + y ^ 2 - 4y = 20 defines a circle in the xy-coordinate plane What is the radius of the circle?
Helga [31]

Answer:

I'll set up the problem and you can do the calculation

Step-by-step explanation:

we need to complete the squares to get the equation in the general form:

{(x - h)}^{2}  +  {(y - k) }^{2}  =  {r}^{2}

where h = the x coordinate of the center

k = the y coordinate of the center

r = the radius

so looking at

{x}^{2}  - 2x

we can see that if use -1 as the constant we have

{(x - 1)}^{2}  =  {x}^{2}  - 2x   + 1

doing the same for y

{y}^{2}  - 4y

we can use -2 as the constant (basically you that the s

quare of the y coefficient )

{(y - 2)}^{2}  =  {y}^{2}  - 4y   + 4

so now we have to add or subtract the constant on the RHS to see what the square of the radius is according to the general form of the equation at the top

20 +1+4=25

Take the square root and you have the radius

german

Answer:

11/381

Step-by-step explanation:

Not sure what the ? after each number means but I'm going to assume they aren't there

so we need find the number of tokens in all which is

44+1414+66=1524

P(red)=44/1524 now reduce giving P(red)=11/381
