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
Solve for A
ab - ac = 2
First, you need to factorize
a(b - c) = 2
a= 2/(b -c)
Answer:
Step-by-step explanation:
When subtracting polynomials, first start with distributing the negative sign to the second polynomial:
Simplify by combining like terms:
X = 23
y = 7
x + y = ?
23 + 7 = 30
ANSWER: x + y = 30
Answer:
C) aₙ = aₙ₋₁ + 200
Step-by-step explanation:
Each term is 200 more than the previous term. So:
aₙ = aₙ₋₁ + 200
