For the given position vectors (t) compute the unit tangent vector (t) for the given value of t. A) Let (t)=(cos4t, sin4t).
Then (π4)= ( , )
B) Let (t)=(t^2,t^3).
Then (5)= ( , )
C) Let (t)=e4t+e−5t+t.
Then (−4)=

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.

the answer is  

a.
