Suppose that a particle following the given path c(t) flies off on a tangent at t = t0. Compute the position of the particle at
Svetach [21]

Answer:

(30,35,0)

Step-by-step explanation:

We are given that

C(t)=(2t^2,t^3-4t,0)

t_0=3,t_1=4

The velocity of particle,v(t)=c'(t)=(4t,3t^2-4,0)

Substitute t_0=3

C(3)=(2(3)^2,(3)^3-4(3),0))=(18,15,0)

v(3)=(4(3),3(3)^2-4,0)=(12,23,0)

The tangent line at t=3 is given by

l(t)=c(2)+(t-3)v(3)=(18,15,0)+(t-3)(12,23,0)

Now, substitute t=4

l(4)=(18,15,0)+(4-3)+(12,23,0)=(18,12,0)+(12,23,0)

l(4)=(30,35,0)

Hence, the position of particle  at t_1=4=(30,35,0)

Three vertices of a rectangle have coordinates (–6, 2), (–6,–1), and (4, 2).
Allushta [10]
The correct answer would be C., I believe, because you take the opposite of the coordinate and subtract one. Hope this was helpful! (:

1. What is the role of humans/technology in the introduction of invasive species?
diamong [38]

Answer:

Invasive species are primarily spread by human activities, often unintentionally. People, and the goods we use, travel around the world very quickly, and they often carry uninvited species with them. Ships can carry aquatic organisms in their ballast water, while smaller boats may carry them on their propellers.
