Answer:

Area = 10

Step-by-step explanation:

Here is how to solve:

(x1y2+x2y3+x3y1-y1x2-y2x3-y3x1) / 2

In your case

A(2,2) is x1=2, y1=2

B(6,2) is x2=6, y2=2

C(6,7) is x3=6, y3=7

((2x2)+(6x7)+(6x2)-(2x6)-(2x6)-(7x2)) divided by 2 = 10

Area = 10

Answer:

Mass=1068gr

Step-by-step explanation:

Volume= 7.5 cm x 2.53 cm x 7.15 cm=135.7cm^3

Density=7.87gr/cm^3

Mass=Density*Volume=135.7*7.87=1068gr

An airplane is traveling due east with a velocity of 583 miles per hour. The wind blows at 75 miles per hour at an angle of S58°

ASHA 777 [7]

Answer:

D. 647.8 miles per hour; S86.5°E

Step-by-step explanation:

We assume the wind direction is supposed to be S58°E. Then the bearing of the plane measured clockwise from north is 90°, and the direction the wind is blowing toward has a bearing of 122°. The resultant speed and direction is the sum of the two vectors, which is easily found using a suitable calculator:

583∠90° + 75∠122° = 647.8∠93.5°

The bearing of 93.5° translates to the direction S86.5°E.

_____

An angle east of south is subtracted from 180° (south) to find the equivalent bearing.
