the original cost is "x", which is the 100% of the original price, and we also know that €336 is its price increased by 40%, namely 100% + 40% = 140%, so

On day 15 you would have made 32,768 dollars, which surpasses the price of the car by 12,768 dollars
Given the position function, the velocity function is obtained by taking the derivative:

The velocity is increasing its own derivative is positive, so we also have to find the acceleration by taking another derivative:

To find when
, we first need to know where
:

The quadratic factor is always positive (its discriminant is negative), which leaves one solution at
. To either side of
, we have, for instance,


which indicates that
is increasing for
, making the answer A.
Given:
Required:
To find the probability that the dart land will be in the shaded region.
Explanation:
Area of the circle is given by the formula:

Where r = radius
Thus the area of the circular region

The area of the square is given by the formula:

Thus the area of the given square

The probability of an event is given by the formula:

The probability that the dart land will be in the shaded region

Thus probability

Final answer:
Thus the probability that the dart land will be in the shaded region is 0.349.
