Ответ:
-![\frac{4}{\sqrt{29} }](/tpl/images/1390/7412/181e3.png)
Step-by-step explanation:
The equations for the 1st object :
x₁ = 10 cos(2t), and y₁ = 6 sin(2t)
2nd object :
x₂ = 4 cos(t), y₂ = 4 sin(t)
Determine rate at which distance between objects will continue to change
solution Attached below
Distance( D ) =![\sqrt{(10cos2(t) - 4cos(t))^2 + (6sin2(t) -4sin(t))^2}](/tpl/images/1390/7412/ca513.png)
hence; dD/dt = -![\frac{4}{\sqrt{29} }](/tpl/images/1390/7412/181e3.png)
