A man is standing at a radar base and observes an unidentified plane at an altitude 6000m flying towards the radar base at an an

liubo4ka [24]

Answer:

The speed in of the plane is 115.47 m/sec

Step-by-step explanation:

Given:

Height at which the plane is flying = 6000 m

Angle of elevation at the radar base = 30 Degrees

Angle of elevation at the radar base after one minute = 60 Degrees

To Find:

The Speed of the plane in meter per second = ?

Solution:

Let us use the tangent of the angle to find the distance (d) to a point directly below plane:

<u>when the angle is 30 degrees</u>

$tan(30) = \frac{6000}{d1}$

$d1 = \frac{6000}{tan(30)}$

$d1 = \frac{6000}{0.577}$

d1 = 10392.3 meters

<u>when the angle is 60 degrees</u>

$tan(60) = \frac{6000}{d2}$

$d2 = \frac{6000}{tan(60)}$

$d2 = \frac{6000}{1.732}\\$

d2 = 3464.1 meters

<u>distance travelled by aircraft in 1 min is </u>

=>d1 - d2

=>0392.3 - 3464.1

= 6928.2 m/min

<u>Now converting to m/sec</u>

=> $\frac{6928.2}{60}$

=>115.47 m/sec

Solve the equation.<br> -9x + 1 = -x + 17

xxMikexx [17]

Step-by-step explanation:

-9x + 1 = -x + 17

collect like terms

-9x + x = 17-1

-8x = 16

divide both sides by -8

-8x/-8 = 16/8

x = 2

Asher's gross annual income is $43,908 . He is paid monthly and has 6% deducted from his paychecks for his 401k. His employer ma

Oksanka [162]

----------------------------------------
Find Monthly Income
----------------------------------------
Gross Annually Income = $43 908
Gross Monthly Income = $43 908 ÷ 12
Gross Monthly Income = $3659

----------------------------------------
Paycheck deducted for 401k
----------------------------------------
6% of $3659
= 0.06 x 3659
= $219.54
----------------------------------------
Employer contribution to his 401k
----------------------------------------
4% of $2659
= 0.04 x 3659
= $146.36

----------------------------------------
Total contribution to his 401k
----------------------------------------
$219.54 + $146.36 = $365.90

----------------------------------------
Answer: $365.90 (Answer C)
