What is the radius of a circle whose equation is x^2+y^2-10x+6y + 18=0

rjkz [21]

Answer:

Explanation:

We must write this equation in the form

(

−

)

(

−

)

Where

(

)

are the co ordinates of the center of the circle and the radius is

So the equation is

−

Complete the squares so add 25 on both sides of the equation

−

(

−

)

Now add 9 on both sides

(

−

)

(

−

)

(

)

This becomes

(

−

)

(

)

So we can see that the centre is

(

−

)

and the radius is

The pressure applied to a leverage bar varies inversely as the distance from the object. If 150 pounds is required for a distanc

AlexFokin [52]

Answer:

500 pounds

Step-by-step explanation:

Let the pressure applied to the leverage bar be represented by p

Let the distance from the object be represented by d.

The pressure applied to a leverage bar varies inversely as the distance from the object.

Written mathematically, we have:

$p \propto \dfrac{1}{d}$

Introducing the constant of proportionality

$p = \dfrac{k}{d}$

If 150 pounds is required for a distance of 10 inches from the object

p=150 pounds
d=10 inches

$150 = \dfrac{k}{10}\\\\k=1500$

Therefore, the relationship between p and d is:

$p = \dfrac{1500}{d}$

When d=3 Inches

$p = \dfrac{1500}{3}\\\implies p=500$ pounds$

The pressure applied when the distance is 3 inches is 500 pounds.
