Use the distance formula to determine the distance between (-8,10) and (-6,7)
hjlf

Answer:

Distance: \sqrt{13} units

Step-by-step explanation:

The distance formula is d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} where:

  • d is the distance between points (x_1,y_1) and (x_2,y_2)
  • (x_1,y_1) are the coordinates of the first point
  • (x_2,y_2) are the coordinates of the second point

We are given that:

  • (x_1,y_1)=(-8,10)
  • (x_2,y_2)=(-6,7)

To determine the value of our distance, d, we plug in our given information into the formula and solve for

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

d=\sqrt{(-6-(-8))^2+(7-10)^2}

d=\sqrt{(-6+8)^2+(-3)^2}

d=\sqrt{(2)^2+(-3)^2}

d=\sqrt{4+9}

d=\sqrt{13}

Therefore, the distance between (-8,10) and (-6,7) is \sqrt{13} units.

See the attached graph for a visual.

Joel has 59 songs on his MP3 player he equally divides them 7 groups how many songs will be in each group
Xelga [282]

Joel has 59 songs on his MP3 player he equally divides them 7 groups how many songs will be in each group

Total number of songs = 59

We need to divide them into 7 groups

so we divide 59 by 7

\frac{59}{7}=8.428571

Round the answer to nearest whole number

so 8.42857 rounded to 8

So 8 songs in each group

Find the distance between the points c ( 6, 5) and D(-3, 1),
svet-max [94.6K]

Answer:

see explanation

Step-by-step explanation:

Calculate the distance (d) using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (6, 5) and (x₂, y₂ ) = (- 3, 1)

d = \sqrt{(-3-6)^2+(1-5)^2}

  = \sqrt{(-9)^2+(-4)^2}

  = \sqrt{81+16}

  = \sqrt{97} ≈ 9.85 ( to 2 dec. places )
