Marsha sees an airplane flying overhead. The spot on the ground that is directly under the plane is 3,600 feet from Marsha's hou

Rudiy27

The elevation of the plane is 3600 ft

Let

h = elevation of plane,
d = distance from Marsha's house to spot on ground below plane = 3600 feet and
Ф = angle of elevation of plane = 45°

From the triangle, we have the trigonometric ratio

tanФ = h/D

<h3>Elevation of the plane</h3>

Making h subject of the formula, we have

h = DtanФ

substituting the values of the variables into the equation, we have

h = DtanФ

h = 3600 ft × tan45°

h = 3600 ft × 1

h = 3600 ft

So, the elevation of the plane is 3600 ft

JK and LM are straight lines. Find /NOK.<br> ( help me pls)<br>

VashaNatasha [74]

Answer:

$NOK = 58$

Step-by-step explanation:

Given

$JOM = 108$

$LON = 50$

Required

Find NOK

From the attached triangle, we have:

$LOK = JOM =108$ --- Corresponding angles

And

$LOK = LON + NOK$

Substitute for LOK and LON

$108= 50+ NOK$

Make NOK the subject

$NOK = 108 - 50$

$NOK = 58$

Which of the following is equivalent to x^-1/2<br><br>1) -1/2x <br>2) -√x<br>3) 1/√x<br>4) -1/2x

irina [24]

Answer:

Option (3) is correct.

Step-by-step explanation:

We need to find the expression that is equivalent to $x^{-1/2}$ .

The property is : $x^{-a}=\dfrac{1}{x^a}$

Here, a = 1/2

So,

$x^{-1/2}=\dfrac{1}{x^{1/2}}$

We know that, $x^{1/2}=\sqrt{x}$

$\dfrac{1}{x^{1/2}}=\dfrac{1}{\sqrt{x} }$

So, $x^{-1/2}$ is equivalent to $\dfrac{1}{\sqrt{x} }$

Hence, the correct option is (3).
