An airplane heading due east has a velocity of 210 miles per hour. A wind is blowing from the north at 38 miles per hour. What i

Nimfa-mama [501]

Answer:

The resultant velocity of the airplane is 213.41 m/s.

Step-by-step explanation:

Given that,

Velocity of an airplane in east direction, $v_1=210\ mph$

Velocity of wind from the north, $v_2=38\ mph$

Let east lies in the direction of the positive x-axis and north in the direction of the positive y-axis.

We need to find the resultant velocity of the airplane. Let v is the resultant velocity. It can be calculated as :

$v=\sqrt{v_1^2+v_2^2}$

$v=\sqrt{(210)^2+(38)^2}$

v = 213.41 m/s

So, the resultant velocity of the airplane is 213.41 m/s. Hence, this is the required solution.

Suppose that the function fis defined on the interval (-2,2) as follows. <br>find f(-1) f(0.5) f(1)

frosja888 [35]

Answer:

Step-by-step explanation:

Hello,

-1 <= -1 < 0

so f(-1)=-1

0 <= 0.5 < 1

so f(0.5)=0

1 <= 1 < 2

so f(1)=1

Thank you.
