This problem is about the difference between distance and displacement.
The distance is how many kilometers has the car covered, the displacement is how far from the original point is the car now, and does not depend on the path followed, but it is the shortest path that connects two points.
a) In this part, they ask you for the distance. From the southernmost to the northernmost point of the circumference, the car has traveled half of the circumference, therefore:
distance = circumference ÷ 2 = 2.7km ÷ 2 = 1.35km
b) In this part, you are asked for the displacement, which in this case is the diameter of the circumference:
displacement = diameter = circumference ÷ π = 2.7km ÷ 3.14 = 0.86km = 860m
Answer:
It's a parabola
Step-by-step explanation:
If you write the equation as
x =3y2
, you can see that you are in the form
f
(y)=3y2
. This is a quadratic polynomial in
y
, which means that it represents a parabola with axis parallel to the
x axis.
0.87 = 87/100 <=== this is the fraction
The answer would be -4.5/5. You would have to plot the number in between -2 and - 1 4/5. Hope this helps!
