X^2+4x+y^2-10y+20=30 find the center of the circle by completing the square
swat32

Answer:

a). Center of the circle = (-2, 5)

b). Equation of the line ⇒ y = -\frac{4}{5}x+\frac{58}{5}

Step-by-step explanation:

Equation of the circle is,

x² + 4x + y²- 10y + 20 = 30

a). [x² + 2(2)x + 4 - 4] + [y²- 2(5)y + 25] - 25 + 20 = 30

   [x² + 2(2)x + 4] - 4 + [y² - 2(5)y + 25] - 25 + 20 = 30

   (x + 2)² + (y - 5)²- 29 + 20 = 30

   (x + 2)² + (y - 5)²- 9 = 30

   (x + 2)² + (y - 5)² = 39

By comparing this equation with the standard equation of a circle,

    Center of the circle is (-2, 5).

b). A point (2, 10) lies on this circle.

    Slope of the line joining this point to the center (-2, 5),

    m_{1}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

          = \frac{10-5}{2+2}

          = \frac{5}{4}

    Let the slope of the tangent which is perpendicular to this line is 'm_{2}'

    Then by the property of perpendicular lines,

          m_{1}\times m_{2}=-1

          \frac{5}{4}\times m_{2}=-1

                 m_{2}=-\frac{4}{5}

   Now the equation of the line passing though (2, 10) having slope m_{2}=-\frac{4}{5}

           y - y' = m_{2}(x-x')

           y - 10 = -\frac{4}{5}(x-2)

           y - 10 = -\frac{4}{5}x+\frac{8}{5}

                  y = -\frac{4}{5}x+\frac{8}{5}+10

                  y = -\frac{4}{5}x+\frac{58}{5}

Therefore, equation of the line will be, y = -\frac{4}{5}x+\frac{58}{5}

Can someone help me find the value of z? ⅔z + 1 = 13
sergey [27]

Answer:

z = 18

Step-by-step explanation:

Given: ⅔z + 1 = 13

Subtract one from both sides: ⅔z = 12

Multiply both sides by the inverse of 2/3, which is 3/2: z = 18

Have a nice day!

    I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)

Jim’s father is older than 40 but younger than 50.If you can divide his age by 2,4,5,8,or 10 ,there will be a remainder of 1. Ho
CaHeK987 [17]

Answer:

Step-by-step explanation:

all you have to do is divide each number by 4, 41, 42, 43, 44, 45, 46, 47, 48, 49 ,and 50 until you get a remainder of 1. what I mean is do 2 divided by all the number from 40 50 and do the same with 4,5,8 and 10 until you find one of them that has a remainder of 1. (is a lot of work sorry could't tell you the anwer)

murzikaleks [220]

Answer:

2/3 probability that the answer choice which rohit selects for question is wrong.

Step-by-step explanation:

Completing the question :- what is probability that the answer choice which rohit selects for question is wrong.

Answer :

Since there are 3 possible options provided out of which 1 is correct. So probability of correct answer is 1/3. probability of incorrect answer is 2/3.

So, there is 2/3 probability that the answer choice which rohit selects for question is wrong.

Adrian earns $3600 per month. he spends 1/4 of his income on rent, 2/5 on food, 1/9 on activities, and he saves the rest. how mu
murzikaleks [220]

he saves $860 per month

calculate each of his outgoings

rent = \frac{1}{4} × $3600 = \frac{3600}{4} = $900

food = \frac{2}{5} × $3600 = \frac{2(3600)}{5} = $1440

activities = \frac{1}{9} × $3600 = \frac{3600}{9} = $400

savings = $3600 - ( 900 + 1440 + 400 ) = $860
