Because p squared is equal to -25, the square root of -25 is equal to p.

Because of this, finding the square root of -25 will give us our answer.

$\sqrt{-25}$ = 5i

Therefore, p = 5i or p = $\sqrt{-25}$ .

<em>Hope this helped! :)</em>

Answer:

p = - 5i or p = 5i

Step-by-step explanation:

Noting $\sqrt{-1}$ = i

Given

p² = - 25 ( take the square root of both sides )

p = ± $\sqrt{-25}$ = ± $\sqrt{25(-1)}$ = ± 5i

Thus

p = - 5i or p = 5i

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:

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

3 (6+3n) = 5n + 18 + 3n

amid [387]

Answer:

n = 0

Step-by-step explanation:

Multiply parenthesis by 3 and get:

1.) 18 + 9n = 5n + 18 + 3n

Then cancel the equal terms:

9n = 5n + 3n

Collect like terms:

9n = 8n

Move variable to the left:

9n - 8n = 0

n + 0

Plugin the value of 0 into x:

3 (6 + 3 x 0) = 18

5 x 0 + 3 x 0 + 18 = 18

*If the plugged in value have the same result than the answer is correct because 18 + 18.

John and his son are building a boxcar for a group competition. According to the rules of the competition, the length of the car

kozerog [31]

Answer:

x ≥ y + 2

0.50 (x) (x+3) + 2.25 (4) (y) ≤ 50

Step-by-step explanation:

x = width of the car

x+3 = length of the car

y = radius of the car

The width must be at least 2 inches greater than the radius, so:

x ≥ y + 2

The total cost must be no more than $50, so:

0.50 (x) (x+3) + 2.25 (4) (y) ≤ 50
