Answer:
Todos los lados de un cuadrado son iguales. Hay 4 lados en un cuadrado. Entonces, para encontrar un lado, debemos dividir el área por 4.
432/4 = 108, Un lado del cuadrado mide 108 metros.
Answer:
δL/δt = 634,38 ft/s
Step-by-step explanation:
A right triangle is shaped by ( y = distance between aircraft and ground which is constant and equal to 405 f ) a person who is at ground level 3040 f away from the tower distance x = 3040 f and the line between the aircraft and the person. Then we can use Pythagoras theorem and write
L ( distance between aircraft and person )
L² = x² + y² or L² = x² + (405)²
Taken partial derivatives with respect to t we get:
2*L*δL/δt = 2*x*δx/t + 0
Then L*δL/δt = x*δx/dt
At the moment of the aircraft passing over the tower
x = 3040 ft δx/δt = 640 ft/s and L = √ ( 3040)² + (405)²
So L = √9241600 + 164025 L = √9405625 L ≈3066,9 ft
Then:
δL/δt = 3040*640/ 3066,9 units [ ft * ft/s / ft ] ft/s
δL/δt = 634,38 ft/s

Answer:
Table A and Graph A
Step-by-step explanation:
See the attached tables and graphs.
Table A gives the ordered pairs (1,2), (2,4) and (3,6).
Take the first two pairs of points.
The equation of the straight line passing through those points will be
⇒ y = 2x
Therefore, the table A represents the equation y= 2x.
Now, as shown in graph A, the points (0,0) and (1,2) and (2,4) through which this equation of straight line passes.
Therefore, the equation y = 2x is represented by graph A.
Hence, Table A and Graph A are the answers.
