Answers

Answer 1

Answer:

its B

x^2/680,625 - y^2/3,319,375 = 1

Answer 2

The equation that be used to determine possible locations of the origin of the sound [tex]\dfrac{ x^2}{680,625} - \dfrac{ y^2}{3,319,375 }= 1[/tex]

What is a system of equations?

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

What is the value of x?

Answer:

Step-by-step explanation:

Since UV is a tangent then ∠ WUV = 90°

WZ = WU = x - 1 ( both radii of the circle ) , then

WV = x - 1 + 2 = x + 1

Using Pythagoras' identity in the right triangle

WU² + UV² = WV² , that is

(x - 1)² + (2x - 4)² = (x + 1)² ← expand factors using FOIL

x² - 2x + 1 + 4x² - 16x + 16 = x² + 2x + 1

5x² - 18x + 17 = x² + 2x + 1 ← subtract x² + 2x + 1 from both sides

4x² - 20x + 16 = 0 ← divide through by 4

x² - 5x + 4 = 0

(x - 1)(x - 4) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 1 = 0 ⇒ x = 1

x - 4 = 0 ⇒ x = 4

But x ≠ 1 as radius x - 1 = 0

Thus x = 4 → B

help please HUREEEEYTTT

Answers

The answer is B. (7,-10).

Since A is moved down by 11 units and moved right by 4. We can use Point D’s coordinate to find where Point D1 will be.

Original coordinate of D: (3,1)

Coordinate of D1
= (3+4 , 1-11)

= (7,-10)

You plus 4 because it’s moved to right by 4 units. And minus -11 because it’s moved down by 11 units.

If the figure is,
- Moved up, we plus
- Moved down, we minus
- Moved right, we plus
- Moved left, we minus

For right and left, we use the x-coordinates. And for up and down, we use the y-coordinate.

Hope this helps!
