The question is really quite easy. You just have to find the distance between the sea level and the point down the water. Make an illustration about the problem to visualize it better. The picture is shown in the attached picture. The distance we want to get is denoted as x. The solution is as follows:

x = 4.7 - 0.5 = 4.2 m

Hope this helps!

The following tables each show the inventory of a warehouse and the number of orders for four different products which have been
snow_lady [41]
Orders: x
Inventory: y

1) First table
x2-x1=6-3→x2-x1=3
y2-y1=1920-1960→y2-y1=-40

x3-x2=9-6→x3-x2=3=x2-x1
y3-y2=1900-1920→y3-y2=-20 different to y2-y1=-40. The table does not represent a linear relationship.

2) Second table
x2-x1=7-5→x2-x1=2
y2-y1=1860-1900→y2-y1=-40

x3-x2=9-7→x3-x2=2=x2-x1
y3-y2=1820-1860→y3-y2=-40=y2-y1

x4-x3=11-9→x4-x3=2=x3-x2
y4-y3=1780-1820→y4-y3=-40=y3-y2

x5-x4=13-11→x5-x4=2=x4-x3
y5-y4=1740-1780→y5-y4=-40=y4-y3

The table represents a linear relationship.

3) Third table
x2-x1=2-1→x2-x1=1
y2-y1=1000-2000→y2-y1=-1000

x3-x2=3-2→x3-x2=1=x2-x1
y3-y2=500-1000→y3-y2=-500 different to y2-y1=-1000. The table does not represent a linear relationship.

4) Fourth table
x2-x1=6-4→x2-x1=2
y2-y1=1640-1840→y2-y1=-200

x3-x2=8-6→x3-x2=2=x2-x1
y3-y2=1360-1640→y3-y2=-280 different to y2-y1=-200. The table does not represent a linear relationship.

Answer: The second <span>table best represents a linear relationship.</span>

Use intercepts to graph the linear equation 5x+3y=30 .
Fantom [35]

Answer: (6, 0) (0, 10)

Step-by-step explanation:

Intercepts occur when the axis is crossed, which is when the other axis is at 0. Plug in 0 for x & y. 5x + 0 =30 means x = 6. 3y + 0 =30 means y is 10.
