A bullet is fired into the air with an initial velocity of 881 feet per second at an angle of 55° from the horizontal. Find the
snow_lady [41]

The horizontal and vertical vector components of the velocity vector V, namely Vx and Vy are; 505.32 ft/s and 721.57 ft/s respectively

<h3>Horizontal and Vertical components of vectors</h3>

For ease of computation since vectors have magnitude and direction; they are resolved into horizontal and vertical components.

By convention, the horizontal, Vx and vertical components, Vy are as follows;

  • Vx = V cos π
  • Vy = V sin π

where π = angle of inclination to the horizontal.

Hence,

  • Vx = 881 × cos55° = 505.32 ft/s

  • Vy = 881 × sin55° = 721.57 ft/s

Darya [45]

Answer:

Step-by-step explanation:

Given that in the past, 35% of the students at ABC University were in the Business College, 35% of the students were in the Liberal Arts College, and 30% of the students were in the Education College.

Table is prepared as follows

                            Bus coll.     Lib Arts coll      Educ. coll        Total

Observed                  90                120                 90                  300

Expected p.c.             35                 35                 30                  100

Expected number     105                105                 90                 300

Percent*300/100

Hence expected frequency for business college = 105

What is the translation of EFG with vertices E(3, 2), F(2, 5), G(−1, 2) by vector − − 1, 4 ?
sesenic [268]

Answer:

The correct answer is (4 , 6); (3 , 9); (0 , 6)

Step-by-step explanation:

In translation by a vector, we simply add or subtract the coordinates of a point with the vector to get the translated coordinates of the point.

Here the vector is 1 , 4.

Thus, the point E(3 , 2) would translate to ( 3+1 , 2+4) = ( 4 , 6 ).

The point F(2 , 5) would translate to ( 2+1 , 5+4) = ( 3 , 9 ).

The point G(-1 , 2) would translate to ( -1+1 , 2+4) = ( 0 , 6 ).
