Write the general equation for the circle that passes through the points (-5,0), (0.4), and (2,4).
Advocard [28]

Answer:

(x-1)^2+(y+19/8)^2=2665/64

Step-by-step explanation:

The general equation of a circle is

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

Substituting the values of the 3 given points:

(-5 - h)^2 + (0 - k)^2 = r^2

(0 - h)^2 + (4 - k)^2 = r^2

(2 - h)^2 + (4 -k)^2 = r^2

Subtracting the second equation from the first:

(-5-h)^2 - h^2 + k^2 - (4 - k)^2 = 0

25 + 10h + h^2 - h^2 + k^2 - 16 + 8k - k^2 = 0

10h + 8k = -9  ------------ (A).

Subtract the third equation for the second:

h^2 - (2 - h)^2 + 0 = 0

h^2 - 4 + 4h - h^2 = 0

4h = 4

h = 1.

Substituting for h in equation A:

10 + 8k = -9

8k = -19

k = -19/8

So r^2 = (-5-1)^2 + (0 + 19/8)^2 =

36  + 361/ 64

= 2665/64

If AD is the altitude to BC, what is the slope of AD?
anygoal [31]

Answer:

Option (C)

Step-by-step explanation:

If AD is the altitude to BC, both the segments AD and BC will be perpendicular to each other.

By the property of perpendicular lines,

m_1\times m_2=-1

where m_1 is the slope of the line AD and m_2 is the slope of BC.

m_2=\frac{y_2-y_1}{x_2-x_1}

     =\frac{8+2}{3-7}

     =-\frac{5}{2}

Now from the given property,

m_1\times (-\frac{2}{5})=-1

m_1=\frac{5}{2}

Therefore, slope of altitude BC = \frac{5}{2}

Option (C) will be the answer.
