Answer: C.It has a negative association
Step-by-step explanation:
The correct question in the attached figure
we know that
the scale is 1 in (scale drawing)= (1/2) foot (actual)-----> 1/(1/2)=2 in/ft
[scale]=[scale drawing]/[actual]
then
[scale drawing]=[scale]*[actual]
therefore
for <span>actual width of the car 8 ft
</span>[scale drawing]=[2 in/ft]*[8 ft]=16 in
<span>
the answer is 16 in</span><span>

Compute the derivative of
at
- this will be the tangent vector - then normalize it by dividing it by its magnitude to get the unit tangent vector
.
