f(x) cannot be 0 or less than zero, but can approach+ infinity
Answer is (0, ∞)
Answer:
The distance covered is 113.75 m
Step-by-step explanation:
As per the question:
The initial velocity of the train, v = 20 m/s
The final velocity of the train, v' = 6 m/s
Uniform deceleration, a = 1.6
Or uniform acceleration, a = - 1.6
<em>Here, the body decelerates, i.e., slows down at a uniform rate thus we take acceleration with negative sign.</em>
Now, to find the distance covered, s:
Using the eqn of Kinemetics:




Answer:
185 minutes.
Step-by-step explanation:
It is possible to model an equation for this, such that

where x represents the number of minutes.
Then, you solve for x:

Answer:
30%
Step-by-step explanation:
14/20 is 70% he gave away, so 30% is left.
