An airplane flying at 600 miles per hour has a bearing of 53°. After flying for 2.5 hours, how far north and how far east will t

serg [7]

Answer:

Eastward distance of airplane = 903 miles

Northward distance of airplane = 1198 miles

Step-by-step explanation:

Consider the sketch attached below.

Let the Eastward distance be represented by x

let the Northward distance be represerted by y

The distance traveled = speed of plane x time

= 600 x 2.5 = 1500 miles

from basic trigonometry of a right angled triangle we have that

$sin(53)=\frac{x}{1500}$

$x=1500\timessin(53) \approx 903 miles$

$cos (53) = \frac{y}{1500}$

$y= 1500cos(53)\approx1198 miles$

∴ Northward distance = 1198 miles

Eastward distance =903 miles

sveticcg [70]

Answer:

x = 0, 4, -2

Step-by-step explanation:

f (x) = 3x (x – 4) (x + 2)

0= 3x (x – 4) (x + 2)

3x = 0, x-4 =0 , x+2 = 0

x = 0, 4, -2
