(a) Differentiate each of the components to get r'(t). The rule is
.. d/dt (a*e^(bt)) = a*b*e^(bt)
The answer you have shown is the correct one.
(b) See the figure. The red curve is the position r(t) for 0 ≤ t ≤ 2. The dashed orange line is the tangent line, whose equation is
.. L(t) = r(0) +r'(0)*t = (2 +2t)i +(3 -3t)j

Using the line of the best fit, the predicted student's score in English test is 48
<h3>How to determine the student's score in English?</h3>
From the question, we have:
Mathematics score = 60
The scores in English tests are plotted on the y-axis.
On the given graph, we have:
(x,y) = (60,48)
This means that when x = 60, the value of y is 48
This in other words means that the student's score in English test is 48
