Answer:
direct relation between distance travelled by a train and its speed, when time is constant.
Step-by-step explanation:
We know that the speed of an object is the total distance covered divided by total time taken. Mathematically, it is given by :
Where
d is distance
t is time taken
It can be seen that relation between the distance and the speed is direction. Hence the correct option is (a) "direct".
Answer:
Correct answer: y = 2x ( ㏑x² + 1)
Step-by-step explanation:
We will use the product rule for this derivation
Let be x² = U and ㏑x² = V
Product rule is:
dy = dU · V + U · dV
y = 2x · ㏑x² + x² · 1/x² · 2x = 2x · ㏑x² + 2x = 2x ( ㏑x² + 1)
y = 2x ( ㏑x² + 1)
