A diameter of a circle has endpoints P(-10,-2) and Q(4,6).

Olenka [21]

The equation for the midpoint is given by:
$P = (\frac{x1 + x2}{2} , \frac{y1 + y2}{2})$
Substituting values we have:
$P = (\frac{-10 + 4}{2} , \frac{-2 + 6}{2})$
$P = (\frac{-6}{2} , \frac{4}{2})$
$P = (-3 , 2)$
We can find the radius of the circle using the equation of distance between points:
$d = \sqrt{(x2-x1)^2 + (y2-y1)^2}$
Substituting values:
$d = \sqrt{(4-(-3))^2 + (6-2)^2}$
$d = \sqrt{(4+3)^2 + (4)^2}$
$d = \sqrt{(7)^2 + (4)^2}$
$d = \sqrt{49 + 16}$
$d = \sqrt{65}$
The equation of the circle is its standard form is:
$(x-xo) ^ 2 + (y-yo) ^ 2 = r ^ 2
$
Where,
(xo, yo): coordinates of the center of the circle
r: radius of the circle
Substituting values:
$(x + 3) ^ 2 + (y-2) ^ 2 = 65
$

Victoria is counting all of quarters and dimes from the family piggy bank for the month. If there are 12 times as many dimes are

saw5 [17]

Let number of quarters in family piggy bank = x

Let number of dimes in family piggy bank = y

Given that "there are 12 times as many dimes are there are quarters". so we can write equation:

y=12x...(i)

Given that " total change is worth $21.75".

We know that 1 quarter = $0.25 and 1 dime = $0.10

So other equation will be :

0.25x+0.10y=21.75...(ii)

Now we just need to solve both equations.

Plug (i) into (ii)

0.25x+0.10y=21.75

0.25x+0.10(12x)=21.75

0.25x+1.2x=21.75

1.45x=21.75

x=15

plug x=15 into (i)

y=12x=12*15=180

Hence final answer is given as:

Number of quarters in family piggy bank = 15

Number of dimes in family piggy bank = 180
