What is the length of a radius of the circle represented by the equation below?

MakcuM [25]

Answer:

Step-by-step explanation:

Given the circle: $x^2 + y^2 - 4x - 4y + 4 = 0$

To determine the length of the radius, we complete the square.

Step 1: Subtract 4 from both sides

$x^2 + y^2 - 4x - 4y + 4 -4= 0-4\\x^2 + y^2 - 4x - 4y = -4$

Step 2: Divide the coefficient of x and y by 2, square it and add it to both sides

$x^2 - 4x+(-2)^2+ y^2 - 4y+(-2)^2 = -4+(-2)^2+(-2)^2$

Step 3: Factorize the Left Hand side and simplify the Right Hand side.

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

Comparing with the standard form of the equation of a circle

$(x-h)^2+ (y-k)^2 = r^2$

r=2

Therefore, the radius of the circle is 2.

5(x+y)-3(y/x) plz help me

Contact [7]

Answer:

$\large\boxed{5(x+y)-3\left(\dfrac{y}{x}\right)=5x+5y-\dfrac{3y}{x}}$

Step-by-step explanation:

$5(x+y)\qquad\text{use the distributive property}\ a(b+c)=ab+ac\\\\=5x+5x\\\\3\left(\dfrac{y}{x}\right)=\dfrac{3y}{x}\\\\5(x+y)-3\left(\dfrac{y}{x}\right)=5x+5y-\dfrac{3y}{x}$

During the calendar year of 1971 a total of 171 deaths were caused by influenza in a city of 450,000 persons. The temporal distr

masha68 [24]

Answer and Step-by-step explanation:

The computation of annual and quarterly mortality rates per 100,000 population is shown below:-

Quarterly mortality rates are

$= \frac{Deaths}{Population\ in\ the\ city}\times Population$

For the first quarter

$= \frac{54}{450,000}\times 100,000$

= 12 death per 100,000 population

For the second quarter

$= \frac{43}{450,000}\times 100,000$

= 9.5 death per 100,000 population

For the third quarter

$= \frac{35}{450,000}\times 100,000$

= 7.7 death per 100,000 population

For the fourth quarter

$= \frac{39}{450,000}\times 100,000$

= 8.6 death per 100,000 population

Now the annual mortality is

$= \frac{Deaths}{Population\ in\ the\ city}\times Population$

$= \frac{171}{450,000}\times 100,000$

= 38 death per 100,000 population

K is the midpoint of JL. If: JK = 5x + 1 and KL = 7x - 3. Find JL

kodGreya [7K]

IF K is the midpoint of JL then JK = KL, so...
5x + 1 = 7x - 3
5x = 7x - 4
-2x = -4
x = 2

JK = 5(2) + 1 = 11
JL = 2 * JK = 2 * 11 = 22
