<span>Remember::
a) velocity is the first derivative of the position vector
b) acceleration is the second derivative of the position vector or, what is the same, the first derivative of the velocity vector.
Using that, you get:
1) given: r(t)=(2+t^2, 3t)
2) v(t) = d r(t) / dt = (2t, 3)
3) a(t) = d (v(t)) / dt = (2,0)
Answer: option </span><span>b) v(t)=(2t, 3) ; a(t)=(2, 0)</span><span>

Answer:6
Step-by-step explanation:
2.5 x 2.5 x 2.5 =15.625 (volume of one cube)
7 x 5 x 3 =105 (volume of cuboid)
105/15.625 =6.75
she cant make 3/4 of a cube therefore the greatest amount of cubes she can make is 6.
998994 and 112111
This seems to be the best numbers

The step in copying a line segment is Using a ruler to measure the given segment, in inches
<h3>What is a line segment?</h3>
A line segment is a piece or part of a line having two endpoints.
In order to draw a line segment of the required length, the simplest and the easiest method is to use a ruler.
The following steps are required to draw a line segment
- Take a scale and check for its start point, which is zero
- Place the scale on the sheet of paper and mark the starting point of the line segment with a dot on the paper. Mark it as x.
- Mark the endpoint of the line segment, that is till the required length, say 8 cm. Mark it as y.
- Draw a straight line joining the two points. We will get a line segment xy of length 8 cm
Therefore, the step in copying a line segment is Using a ruler to measure the given segment, in inches
