Answer:

33

Step-by-step explanation:

Area of a triangle = \frac{bh}{2} \\ (base × height ÷ 2)

A = <u>6 · 11</u>
       2

A = <u>66
</u>       2

A = 33

Which linear inequality is represented by the graph?
laiz [17]
<h2>Answer</h2>

y\leq \frac{1}{2} x+3

<h2>Explanation </h2>

First we are going to find the equation of the solid line passing trough the points (0, 3) and (2, 4).

Using the slope formula:

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

m=\frac{4-3}{2-0}

m=\frac{1}{2}

Now we can use the point slope formula to complete the line equation:

y-y_{1}=m(x-x_{1})

y-3=\frac{1}{2} (x-0)

y-3=\frac{1}{2}x

y=\frac{1}{2}x+3

Since the shaded region is bellow the line y=\frac{1}{2}x+3, the inequality represented in the graph is y\leq \frac{1}{2} x+3.

An airplane is traveling at a speed of 240 miles/hour with a bearing of 110°. The wind velocity is 56 miles/hour at a bearing of
vodka [1.7K]

Answer:

Actual speed = 288 miles per hour

Actual direction angle = 116.38^\circ

Step-by-step explanation:

"Bearing" is the relative position of an object outside the plane compared to the position of the plane.  

Heading the the direction the nose of the plane is pointing.  

Course is the direction that pilot wants the plane to go.  

Wind direction is always the direction the wind is blowing from.  

The airplane is traveling at a speed of 240 miles/hour with a bearing of 110°.  

If the plane is traveling with a bearing of 110° and the wind is blown at a bearing of 325°.  

 325^{\circ}- 110^{\circ} =225^{\circ}

215^{\circ}- 180^{\circ} =35^{\circ}

The Ground speed will be in excess of the airspeed and true direction will be south if the indicated heading.  

The tailwind component is:

56 cos (35^\circ)

And the cross wind component is:

56 sin (35^\circ)  


And that is,

C^2 = (286)^2 + (32)^2


c = 288

So the actual speed of the plane is 288 miles per hour.

The deviation in the direction is:

Let the direction angle be 'x'.

x = tan ^{-1}\left ( \frac{32}{286} \right )=6.38^\circ

So the actual direction angle is 110^\circ+ 6.38^\circ=116.38^\circ.
