Answer:
The position P is:
ft <u><em> Remember that the position is a vector. Observe the attached image</em></u>
Step-by-step explanation:
The equation that describes the height as a function of time of an object that moves in a parabolic trajectory with an initial velocity 
is:
Where 
is the initial height = 0 for this case
We know that the initial velocity is:
82 ft/sec at an angle of 58 ° with respect to the ground.
So:
ft/sec
ft/sec
Thus
The height after 2 sec is:
Then the equation that describes the horizontal position of the ball is
Where
for this case
ft / sec
ft/sec
So
After 2 seconds the horizontal distance reached by the ball is:
Finally the vector position P is:
ft
The company will have a total number of 531 employees
The answer is 19.. substitute -1 into the function whenever you see x put -1 there. This implies that 3+16 =19
Answer:
Step-by-step explanation:
<u>Given</u>
- Base = 1.2 m²
- Height = h
- Number of fish = 6
- Density = 4 fish/m³
<u>Minimum volume required:</u>
<u>Lowest water height:</u>
- V= bh
- h = V/b
- h = 1.5/1.2 = 1.25 m
