A discuss moves from P1 (4,8) to P2 (15,17). What is the lincar displacement in the horizontal and vertical directions? What is
Yakvenalex [24]

Answer:

The horizontal displacement is 11 units, the vertical displacement is 9 units, and the projection angle is 39.3 degrees.

Step-by-step explanation:

We can start using the definition of displacement in one dimension between any 2 points which is the difference between them, so we have

\Delta s = s_2-s_1

And apply it to get the horizontal and vertical displacements.

Once we have found them, we can use trigonometric functions to find the projection angle with respect the horizontal.

Linear displacements.

Using the definition of displacement, we can write the horizontal displacement as

\Delta x = x_2-x_1

So we can use the given points P1:(x_1,y_2)  \text{  and  } P_2: (x_2,y_2) on the displacement formula

\Delta x = 15-4\\\Delta x = 11

In the same manner we can look at the y components of those points to find the vertical displacement

\Delta y = 17-8\\\Delta y =9

Thus the horizontal displacement is 11 units and the vertical displacement is 9 units.

Projection angle.

The projection angle with respect the horizontal is the angle that is made between the line that connects the points P1 and P2 and the horizontal, so we can use the linear displacements previously found to write

\tan(\theta) = \cfrac{\Delta y}{\Delta x}

Solving for the angle we get

\theta = \tan^{-1}\left(\cfrac{\Delta y}{\Delta x}\right)

Replacing values

\theta = \tan^{-1}\left(\cfrac{9}{11}\right)

Which give us

\theta = 39.3^\circ

So the projection angle is 39.3 degrees.

If a giraffe is 9 feet tall, what is its height in decimeters?​
Dmitry [639]

Answer:

The height of the giraffe is 27.432 decimeters.

Step-by-step explanation:

To convert 1 foot to decimeters you would multiply by 3.048.

We need to multiply 9 feet by 3.048 which would give you the answer of 27.432 decimeters.

zlopas [31]
<span>d. y = 15x 900</span>

Although you do not give the rates I assume the answer is D as it is the only positive multiplication. You cannot have negative height.

Which of these expressionis is <br> equivalent to x^4-5x+3/x^2+7
bonufazy [111]

Next time, please list the possible answer choices.  Without them, all I can do is to attempt this problem without having those choices as guidelines.


I must assume that your expression x^4-5x+3/x^2+7 actually meant:

            5x + 3

x^4  -  ---------------

             x^2 + 7

and I assume that this result was one of the several possible answer choices.
