Write the standard equation of the circle with center (-14, -3) that passes through the point (-5,3),

grin007 [14]

Answer:

$(x + 14)^2 + (y + 3)^2 = 117$

Step-by-step explanation:

Equation of a circle:

The equation of a circle with center $(x_0,y_0)$ is given by:

$(x - x_0)^2 + (y - y_0)^2 = r^2$

In which r is the radius.

Center (-14, -3)

This means that $x_0 = -14, y_0 = -3$

$(x - x_0)^2 + (y - y_0)^2 = r^2$

$(x - (-14))^2 + (y - (-3))^2 = r^2$

$(x + 14)^2 + (y + 3)^2 = r^2$

Passes through the point (-5,3),

This means that when $x = -5, y = 3$ . We use this to find the radius squared. So

$(x + 14)^2 + (y + 3)^2 = r^2$

$(-5 + 14)^2 + (3 + 3)^2 = r^2$

$r^2 = 117$

So, the equation of the circle is:

$(x + 14)^2 + (y + 3)^2 = r^2$

$(x + 14)^2 + (y + 3)^2 = 117$

The Marquez family has 4/5 pint of ice cream, if each family member is served 1/5 pint of ice cream, how many people will get ic

julia-pushkina [17]

Answer: 4 people

Step-by-step explanation:

4 times 1/5= 4/5

The 4 goes on top ( numerator ) and the 5 would go on the bottom ( denominator )

Also another way to solve this is to use decimal form.

4 times 0.2 ( 0.2=1/5 )= 0.8
