Answer:
dr/dt = 1.94 units per second
Explanation:
A particle is moving on the x-axis to the right at 2 u/s.
To know how is changing the distance of the particle respect to the point (0,9), on the y-axis, you first take into account that the distance between charge and a point over the y-axis is given by:
(1)
Next, you calculate implicitly the derivative of the equation (1) respect to t:
(2)
Next, you solve the previous equation for dr/dx:
(3)
dx/dt: the speed of the particle on the x-axis = 2
dy/dt: speed of the particle on the y-axis = 0
For the instant given in the statement, you have that:
x = 5
y = 9
Then, you replace the values for x, y, dx/dt and dy/dt in the equation (3):
The speed of change of the distance between particle and point (0,9) is 1.94 units per second

Answer:
The value is
Explanation:
From the question we are told that
The speed of the airplane from the north is
The negative sign is because the direction is towards the south
The speed of the airplane from the east is
The negative sign is because the direction is towards the west
The distance of the southbound plane from the airport is
The distance of the westbound plane is
Generally the distance between the plane is mathematically represented using Pythagoras theorem as
Next differentiate implicitly this equation to obtain the rate at which the distance between the planes changes
So
