Answer:
c = 92/n
Step-by-step explanation:
The equation that describes the inversly proportional relationship is ...
y = k/x
The value of the constant of proportionality can be found from ...
xy = k . . . . . . product of values of independent and dependent variables
__
In this problem, we have c = 23 for n = 4, so the constant of proportionality is ...
k = c×n = (23)(4) = 92
The equation for the relationship is ...
c = 92/n
Answer:
30 m/s
Step-by-step explanation:
Let's say the distance from the first car to the intersection is x, and the distance from the second car to the intersection is y.
The distance between the cars can be found with Pythagorean theorem:
d² = x² + y²
Taking derivative with respect to time:
2d dd/dt = 2x dx/dt + 2y dy/dt
d dd/dt = x dx/dt + y dy/dt
We know that x = 200, dx/dt = -25, y = 150, and dy/dt = -50/3.
To find dd/dt, we still need to find d.
d² = x² + y²
d² = (200)² + (150)²
d = 250
Plugging everything in:
250 dd/dt = (200) (-25) + (150) (-50/3)
dd/dt = -30
The cars are approaching each other at a rate of 30 m/s at that instant.
