The center of a circle is the point (3, 2). if the point (6, −2) lies on this circle, find the standard equation for the circle.

garri49 [273]

Given
centre of circle O(3,2)=O(x0,y0)
point on circle P(6,-2)

Standard equation of circle:
(x-x0)^2+(y-y0)^2=r^2

r=radius of circle
= (distance OP)
= sqrt((6-3)^2+(-2-2)^2)
=sqrt(3^2+(-4)^2)
=sqrt(25)

=>
r^2=(sqrt(25))^2=25

Equation of circle
(x-x0)^2+(y-y0)^2=r^2
(x-3)^2+(y-2)^2=25 ............... standard equation of circle

Ella has 0.5 lbs of sugar. How much water should she add to make the following concentrations? Tell Ella how much syrup she will

muminat

Ella has 0.5 lbs of sugar. 75% syrup

Percent of mass = $\frac{mass of solute}{mass of solution} * 100$

Let the mass of solution is x

Given mass of solute = 0.5

percent of mass = 75

75 = $\frac{ 0.5}{x} * 100$

75x = 0.5 * 100

75 x = 50

x = 0.67

Mass of solution = 0.67

Mass of water = mass of solution - mass of solute (sugar)

= 0.67 - 0.5 = 0.17

So 0.17lb of water is added with 0.5lb of sugar to get 0.67lb of solution.

Answer:

Step-by-step explanation:

3 x 5 =15 + 3 = 18. so 18 over 5 divided by 2 over 5. you flip the 2nd fraction and multiply. the 5s cancel. 18 ÷2 = 9
