Answer:

Undefined

Step-by-step explanation:

The slope on the graph is horizontal so there's no slope and the answer is just y = 3

For a line to be perpendicular to a horizontal line, it is going to be a vertical line.

All vertical lines have an undefined slope.

a researcher in a personal submarine begins at the surface of thr ocean. The submarine descends 20.6 meters and the ascends 5 7/
Mumz [18]

Answer:

Depth = 14.9\ metres

Step-by-step explanation:

Given

Desc = 20.6\ metres

Asc = 5\frac{7}{10}\ metres

Required

Determine the depth

The depth is the distance between the two distances as follows'

Depth = |Desc - Asc|

Substitute values

Depth = |20.6 - 5\frac{7}{10}|

Convert fraction to decimal

Depth = |20.6 - 5.70|

Depth = |14.9|

Depth = 14.9\ metres

The variable Z is inversely proportional to X. When X is 3, Z has the value 6.3333333333333. What is the value of Z when X = 8 R
sveta [45]
Inverse variation is of the form y=k/x or if you prefer yx=k.

z=6.3 bar  I assume you mean 6.33333333 forever

10z-z=63.3333...-6.3333

9z=57

z=57/9  (exact)

Now back to the problem...

xz=k, we are told x=3 and we have shown z=57/9 so we can solve for k, the constant of variation

k=3(57/9)=19

So our equation is:

xz=19, now we wish to know what z is when x=8 so

8z=19  divide both sides by 8

z=19/8  

z=2.375  (exact, no rounding necessary)
