Answer:

1) n^2 – 3 n + 8   4^2 – 3*4 + 8 = 12    

2)    (x^2 – 4 y) / 2      (16 + 12) / 2 = 14

3) 4 * |-7 – 2| = 4 * 9 = 36     Abs -9 = 9  

4) 19 – x^2 = 19 – 25 = -6     (-5)^2 = 25

5) S^2 t – 10 = -8^2 * ¾ -10 = 64 * ¾ - 10 = 38

6) 4 p^2 + 7 q^3 = 4 * 9 + 7 * (-8) =  - 20      (-2)^3 = -8

What is the distance between two points with coordinates (32,12,5) and (20,3,13) in space?​
lozanna [386]

The distance between two points with the given coordinates in space is;

<u><em>Distance = 17 units</em></u>

We are given the coordinates;

(32, 12, 5)

(20, 3, 13)

  • Formula for the distance between two points that have (x, y, z) coordinates is;

d = √((x₂ - x₁)² + (y₂ - y₁)² + (z₂ - z₁)²)

From the equation given to us, we can see that;

x₁ = 32

x₂ = 20

y₁ = 12

y₂ = 3

z₁ = 5

z₂ = 13

  • Using the <em>formula for the distance</em>, we have;

d = √((20 - 32)² + (3 - 12)² + (13 - 5)²)

d = √(144 + 81 + 64)

d = √289

d = 17

Thus, the <em>distance</em> between the two points is 17 units
