Find an equation of the circle whose diameter has endpoints (1,-4) and (-3,6).

MAVERICK [17]

Answer:

$(x+1)^2+(y-1)^2=58$

Step-by-step explanation:

To find the equation of this circle, we must know the center and the radius.

We can find the radius by dividing the value of the distance formula by 2 (since $r=\frac{d}{2}$ ):

$d=\sqrt{(-3-1)^2+(6-(-4))^2}=\sqrt{116}\\r=d/2=\frac{\sqrt{116}}{2}$

We can then find the center of the circle by averaging the coordinates:

$\frac{1+(-3)}{2}=-1$

$\frac{-4+6}{2}=1$

Then, we substitute these values into the equation of a circle:

$(x-(-1))^2+(y-1)^2=(\frac{\sqrt{116}}{2})^2\\(x+1)^2+(y-1)^2=58$

What does it mean when we say that a formula models real-world phenomena?

Deffense [45]

A formula models real-world phenomena when it describes the relationship between the variables of a real life situation. We use formulas in our every day life, but maybe are not aware of it. Some examples of using math formulas in the real world are: - the most obvious example is that we use formulas in the grocery store (multiplication, estimation, percentages,...

- we use formulas while baking (measuring ingredients, understanding ratios and proportions,<span> converting metrics,...)</span>
