A cell tower is located at and transmits a circular signal that covers three major cities. The three cities are located on the c

Lelu [443]

Answer:

$(x+8)^2 +(y-4)^2 = 25$

Step-by-step explanation:

Assuming this complete problem: "A cell tower is located at (-8, 4) and transmits a circular signal that covers three major cities. The three cities are located on the circle and have the following coordinates: G (-4, 7), H (-13, 4), and I (-8, -1). Find the equation of the circle"

For this case the generla equation for the circle is given by:

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

From the info we know that the tower is located at (-8, 4) so then h = -8 and k = 4, so then we need to find the radius. So we have the equation like this: $(x+8)^2 +(y-4)^2 = r^2$

If the 3 points are on the circle then satisfy the equation. We can use the first point (-4,7) and if we replace we can find the value for $r^2$

$(-4+8)^2 +(7-4)^2 =25= r^2$

So then $r = \sqrt{25}=5$

And if we replace the second point we got this:

$(-13+8)^2 +(4-4)^2 = 25 =r^2$

And for the third point we have:

$(-8+8)^2 +(-1-4)^2 = 25 =r^2$

And we got the same result.

So then our final equation is given:

$(x+8)^2 +(y-4)^2 = 25$

If Triangle ABC has vertices A (-1,1), B (4,4) and C (-5,6), and is dilated by the rule (4x, 4y) what would the coordinates of A

olasank [31]

Answer:

(-4,4)

Step-by-step explanation:

So since the rule is (4x, 4y) all you have to do is multiply. -1 x 4 = -4 and 1 x 4 = 4.

If line b is perpendicular to line a, and line c is perpendicular to line a, what is the slope of line c ?

Shalnov [3]

To answer this question, we must find the slope of line b.
We have then:
b = (3 - (- 2)) / (2 - (- 3))
b = 5/5
b = 1
Since the lines b and c are parallel, it follows that their slopes are equal.
Then
mc = b = 1
Answer:
The slope of line c is:
mc = 1
