Find the distance between the pair of points. give an exact answer, and, where appropiate, and apporximation to two decimal plac
atroni [7]
  • Distance Formula: \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}
  • Product rule of radicals: √ab = √a x √b

Using our two points, we can solve for the distance as such:

\sqrt{(4-(-6))^2+(3-(-1))^2}\\ \sqrt{(10)^2+(4)^2}\\ \sqrt{100+16}\\ \sqrt{116}

Now our exact answer may be √116, however using the product rule of radicals we can further simplify the radical as such:

√116 = √4 x √29 = 2√29.

  • Exact Answer: <u>√116 or 2√29</u>
  • Approximate Answer: <u>10.77</u>

A boat is anchored 2.2 km due south of a lighthouse. Along the shore, the town of Beachton is 16.8 km due east of the lighthouse
Pavlova-9 [17]
Distance from the boat to the town:
d² = 2.2² + 16.8²
d² = 4.84 + 282.24
d² = 287.08
d = √287.08
d = 16.9434 ≈ 16.9 km

URGENT WILL MARK BRAINLIEST
DiKsa [7]

Answer:

x=2, y=2

Step-by-step explanation:

3x + y = 8

2x + 4y = 12

Multiply the first equation by -4

-12x -4y = -32

Then add to the second equation

-12x -4y = -32

2x + 4y = 12

------------------------

-10x + 0y = -20

-10x = -20

Divide by -10

-10x/-10 = -20/-10

x =2

Now find y

3x+y = 8

3(2)+y = 8

6+y = 8

y = 8-6

y =2

Y = -9x - 2; (4, -37)
Karo-lina-s [1.5K]

Answer:

B. No the ordered pair does not satisfy the equation

Step-by-step explanation:

y = -9x - 2

Substitute the point in and see if it is true

-37 = -9(4) -2

-37 = -36 -2

-37 = -38

This is not true so the point is not a solution
