Answer:

x = -\dfrac{25}{13}

Step-by-step explanation:

\log_3{x + 4} - \log_3{x + 2} = \log_3 {27}

\log_3 \dfrac{x + 4}{x + 2} = \log_3 {27}

\dfrac{x + 4}{x + 2} = 27

x + 4 = 27(x + 2)

x + 4 = 27x + 54

-26x = 50

x = -\dfrac{50}{26}

x = -\dfrac{25}{13}

A graph displays point A (5, 3, 4) and point B (−4, 2, 6). Calculate the approximate distance each point is from the origin. Rou

Distance from the origin to the points  ≈ 0.41.

<h3>What is the distance between two points ( p,q) and (x,y)?</h3>

The shortest distance (length of the straight line segment's length connecting both given points) between points ( p,q) and (x,y) is:

D = √[(x-p)² + (y-q)²]  

Point A (5, 3, 4) and point B (−4, 2, 6) are located away from the origin (0,0,0), and the points from the origin to this points are expressed as OB - OA where;

Let OB is the distance from the origin to the point B

Let OA is the distance from the origin to the point A

Using the formula for calculating the distance between two points;

OA = √(z2-z1)²+(y2-y1)²+(x2-x1)²

OA = √(4-0)²+(3-0)²+(5-0)²

OA = √(16)+(9)+(25)

OA = √50

OA = 7.071

Similarly;

OB = √(6-0)²+(2-0)²+(-4-0)²

OB = √(6)²+(2)²+(-4)²

OB = √36+4+16

OB = √56

OB = 7.4833

Distance from the origin to the points = 7.4833 - 7.071= 0.4123

Distance from the origin to the points  ≈ 0.41

10.79/1200=.009
.009*1200=10.79 this is a double check to make sure our price per square foot is correct.

.009*4000=$36.00

It will cost $36.00 to seed the 4,000 square feet at that price.
