A circle is centered at the point (5, -4) and passes through the point (-3, 2).

zepelin [54]

Answer:

(x-5)^2+(y+4)^2=100

Step-by-step explanation:

As we know the given points

Center = (5, -4)

and

Point on circle = (-3,2)

The distance between point on circle and center will give us the radius of circle

So,

The formula for distance is:

$\sqrt{(x_{2}-x_{1} )^{2}+(y_{2}-y_{1})^{2}}\\Taking\ center\ as\ point\ 1\ and\ the\ other\ point\ as\ point\ 2\\d=\sqrt{(-3-5)^{2}+(2-(-4))^{2}}\\d=\sqrt{(-8)^{2}+(2+4)^{2}}\\d=\sqrt{(-8)^{2}+(6)^{2}}\\\\d=\sqrt{64+36}\\d=\sqrt{100} \\ d=10\\So\ the\ radius\ is\ 10$

The standard form of equation of circle is:

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

where h and k are the coordinates of the center. So putting in the value:

$(x-5)^{2}+(y-(-4))^{2}=(10)^{2}\\(x-5)^{2}+(y+4)^{2}=100$

A company makes 140 bags.

Igoryamba

Answer: 41/75 or 54.67%

Step-by-step explanation:

Buttons --- yes, zips --- yes = 45 (compute as 150 - 37 - 45 - 23)

Buttons --- yes, zips --- no = 37

Buttons --- no, zips --- yes = 45

Buttons --- no, zips --- no = 23

Therefore, 82 out of 150 bags have buttons so probability = 82/150 = 41/75

At Gas ‘n’ Wash, gasoline sells for $4.00 a gallon and a car wash costs $12. Helisa wants to have her car washed and keep her to

maks197457 [2]

Answer:

g = 12

Step-by-step explanation:

Inequality is 4g + 12 < 60

Solving for g,

4g < 60 - 12

4g < 48

Divide both sides by 4,

g < 48 / 12

g < 12

The total amount of gas she can buy is 12 gallons
