Find all solutions to the following equation

Mathematics
1 answer:
USPshnik [31]3 years ago
6 0

Answer:

x = -1

Step-by-step explanation:

-2/ ( x * (x+2)) = ( x+3) / ( x+2)

Using cross products

-2 ( x+2) = ( x+3) x* (x+2)

Divide each side by (x+2)   This means x cannot equal -2 because we are dividing by 0

-2 = x ( x+3)

Distribute

-2 = x^2 +3x

Add 2 to each side

0 = x^2 + 3x+2

Factor

0 = ( x+2) (x+1)

Using the zero product property

x+2 = 0  x+1 = 0

x = -2    x = -1

But above we said x cannot equal -2

so x = -1

Scientists studying dolphin echolocation simulate the projection of a bottlenose dolphin's clicking sounds using computer
lina2011 [118]

Step-by-step explanation:

The equation of a parabola with focus at (h, k) and the directrix y = p is given by the following formula:

(y - k)^2 = 4 * f * (x - h)

In this case, the focus is at the origin (0, 0) and the directrix is the line y = -1.3, so the equation representing the cross section of the reflector is:

y^2 = 4 * f * x

  = 4 * (-1.3) * x

  = -5.2x

The depth of the reflector is the distance from the vertex to the directrix. In this case, the vertex is at the origin, so the depth is simply the distance from the origin to the line y = -1.3. Since the directrix is a horizontal line, this distance is simply the absolute value of the y-coordinate of the line, which is 1.3 inches. Therefore, the depth of the reflector is approximately 1.3 inches.
