Which of the following is an equation of a circle in

DaniilM [7]

Answer:

$x^2 + (y - 4)^2 = \dfrac{25}{9}$

Step-by-step explanation:

The equation of a circle with center at (h, k) and radius r is

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

You have center (0, 4).

We get:

$(x - 0)^2 + (y - 4)^2 = r^2$

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

To find the radius, we use the distance formula to find the distance from the center of the circle to the given point on the circle.

$r = d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

$r = \sqrt{(\dfrac{4}{3} - 0)^2 + (5 - 4)^2}$

$r = \sqrt{(\dfrac{4}{3})^2 + 1^2}$

$r = \sqrt{\dfrac{16}{9} + \dfrac{9}{9}}$

$r = \sqrt{\dfrac{25}{9}}$

We need r^2 in the equation of the circle, so

$r^2 = \dfrac{25}{9}$

The equation of the circle is

$x^2 + (y - 4)^2 = \dfrac{25}{9}$

At a soccer match , 60% of the spectators are men and the rest are women and children .The number of children is 2/3 of the wome

Aneli [31]

Answer:

Step-by-step explanation:

We need a series of equations to be able to sub back and forth into one another in order to get this down to one variable, s for spectators. This is what we know from the info (in algebraic expression/equation form):

.6s = men (60% of the spectators are men)

.4s = women + children (40% of the spectators are women and children)

# of children = 2/3 women

# of men = women + 252 (There are 252 more men than women) and

# women = men - 252

Those are the equations we need to solve for the number of spectators.

Start at the top with

.6s = men. We know that the number of men = women + 252, so

.6s = women + 252.

.4s = women + children. We know that the number of children is 2/3 the number of women, so

.4s = women + 2/3 women. If the number of men = women + 252, then

.4s = men - 252 + 2/3(men - 252) which simplifies to

.4s = 3/3 men - 252 + 2/3 men - 168 and

.4s = 5/3 men - 420 and

.4s = s - 420 and

-.6s = -420 so

s = 700
