Answer:

Neither, why... for it to be direct or inverse variation, the model has to fit either y=k/x or y=kx, it may not have a y-intercept at all if it is inverse variation and it must have a y-intercept of 0 for it to be direct variation.

Step-by-step explanation:

The statement y=2 is quite specific. Because k is positive, y increases as x increases. So as x increases by 1, y increases by 1.5. Inverse Variation: Because k is positive, y decreases as x increases.  yx is a constant number -8. The constant of variation, k , is 23 . Inverse Variation

An inverse variation can be represented by the equation xy=k or y=kx .

That is, y varies inversely as x if there is some nonzero constant k such that, xy=k or y=kx where x≠0,y≠0 .

Suppose y varies inversely as x such that xy=3 or y=3x . That graph of this equation shown.

Answer:

a. Sketch is given in the attachment

b. [tex]V_{p}[/tex] = (0,-525)

c. [tex]V_{w}[/tex] = ([tex]\sqrt{2}[/tex],[tex]\sqrt{2}[/tex])  

d. [tex]V_{g}[/tex] = (60[tex]\sqrt{2}[/tex], 60[tex]\sqrt{2}[/tex]  - 525)

e. Actual Speed = |[tex]V_{g}[/tex]| = 448.3 MPH

Direction = Ф = - 79.1°

Direction = Ф = 280.9° with respect to x - axis.

Step-by-step explanation:

a. Sketch the scenario on the x-y axis.

Where,

Velocity of the plane relative to air = [tex]V_{p}[/tex]

Velocity of the jet stream = [tex]V_{w}[/tex]

Velocity of the plane relative to ground = [tex]V_{g}[/tex]

Solution:

Note: Solution is given in the attachment. Please refer to the attachment for the sketch.

b. Express the velocity of the plane relative to the air as a vector.

Solution:

[tex]V_{p}[/tex] = |[tex]V_{p}[/tex]| cosФi + |[tex]V_{p}[/tex]| sinФj

where,

|[tex]V_{p}[/tex]| = magnitude of the vector.

|[tex]V_{p}[/tex]| =  525 MPH

Ф = 270° w.r.t to x - axis. (See the sketch in the attachment)

[tex]V_{p}[/tex] = |[tex]V_{p}[/tex]| cosФi + |[tex]V_{p}[/tex]| sinФj

Plug in the values into this equation to express it in the vector form as required.

[tex]V_{p}[/tex] = (525) cos270i + (525) sin270j

As, Cos270 = 0

and

Sin270 = -1

So,

[tex]V_{p}[/tex] = (525) (0)i + (525) (-1)j

[tex]V_{p}[/tex] = 0i -525j    

[tex]V_{p}[/tex] = (0,-525)  

c. Express the velocity of the jet stream as a vector.

Solution:

Velocity of the jet stream as a vector.

[tex]V_{w}[/tex] = |[tex]V_{w}[/tex]| cosФi + |[tex]V_{w}[/tex]| sinФj

where,

|[tex]V_{w}[/tex]| = magnitude of the vector.

|[tex]V_{p}[/tex]| =  120 MPH

Ф = 45°  (See the sketch in the attachment)

[tex]V_{w}[/tex] = |[tex]V_{w}[/tex]| cosФi + |[tex]V_{w}[/tex]| sinФj

Plug in the values into this equation to express it in the vector form as required.

[tex]V_{w}[/tex] = (120) cos45i + (120) sin45j

As, Cos45 = [tex]\frac{1}{\sqrt{2} }[/tex]

and

Sin45 =  [tex]\frac{1}{\sqrt{2} }[/tex]

So,

[tex]V_{w}[/tex] = (120) ([tex]\frac{1}{\sqrt{2} }[/tex])i + (120) ([tex]\frac{1}{\sqrt{2} }[/tex])j

[tex]V_{w}[/tex] = 60[tex]\sqrt{2}[/tex]i +60[tex]\sqrt{2}[/tex]j    

[tex]V_{w}[/tex] = ([tex]\sqrt{2}[/tex],[tex]\sqrt{2}[/tex])  

d. Find the velocity of the plane relative to the ground.

Solution:

Velocity of the plane relative to the ground = Sum of velocity of plane relative to the air and velocity of the jet stream

[tex]V_{g}[/tex] = [tex]V_{p}[/tex] + [tex]V_{w}[/tex]

[tex]V_{g}[/tex] = 0i -525j    +  60[tex]\sqrt{2}[/tex]i +60[tex]\sqrt{2}[/tex]j    

[tex]V_{g}[/tex] = 60[tex]\sqrt{2}[/tex]i + 60[tex]\sqrt{2}[/tex]  - 525j

[tex]V_{g}[/tex] = (60[tex]\sqrt{2}[/tex], 60[tex]\sqrt{2}[/tex]  - 525)

e. Find the actual speed and direction of the plane relative to the ground. Round to the  tenths.

Solution:

Actual Speed = |[tex]V_{g}[/tex]|  = magnitude of the velocity of the plane relative to the ground.

Actual Speed = |[tex]V_{g}[/tex]| = [tex]\sqrt{(60\sqrt{2}) ^{2} + (60\sqrt{2}-525) ^{2} }[/tex]

Actual Speed = |[tex]V_{g}[/tex]| = 448.3 MPH

Direction = Ф = [tex]tan^{-1}[/tex] ([tex]\frac{60\sqrt{2}-525 }{60\sqrt{2} }[/tex])

Direction = Ф = - 79.1°

To find out the direction with respect to x - axis.

Direction = Ф = 360 - 79.1

Direction = Ф = 280.9°

Answer:

the answer would be about 28.60 km

Answer:

28 KM

Step-by-step explanation:

As an estimation we are told 5 miles is 8 km

mathematically , 5 miles = 8 KM

So , therefore 1 miles = 8/5 KM

now just , multiply 17.8 with 8/5

Answer:

7.2º

Step-by-step explanation:

all polygon's exterior angles measure 360º, so we just need to divide by 50 to get and individual exterior angle measure. 360/50=7.2º

The measure of an exterior angle of a regular 50-gon should be considered as the 7.2º.

Since we know that

All polygon's exterior angles should have the total of 360º,

So basically we divide 360 by 50 so that the measure of an exterior angle should be determined

i.e.

[tex]= 360\div 50[/tex]

= 7.2 degrees

Hence, The measure of an exterior angle of a regular 50-gon should be considered as the 7.2º.

[tex]\frac{\sqrt{9-x^2} }{x}[/tex]

Step-by-step explanation:

The simplification of the following equation is:

Given that

[tex]= \sqrt{\frac{9-x^2}{x^2} } \\\\=\frac{\sqrt{9-x^2} }{\sqrt{x^2} } \\\\=\frac{\sqrt{9-x^2} }{x}[/tex]

Here we assume [tex]\sqrt{x^2}[/tex] be x

Hence, in this way it should be simplified
