Ответ:
Given :
A circle is inscribed in a square with a side length of 144.
So, radius of circle, r = 144/2 = 72 units.
To Find :
The probability that the point is inside the circle.
Solution :
Area of circle,
Area of square,
Now, probability is given by :
Therefore, the probability that the point is inside the circle is 0.785 .

See explanation below.
Step-by-step explanation:
Part A:
(i). They both correct because they could have a third degree polynomial that crosses the x-axis 3 times.
(ii). To find the zero's of the first one, set function equal to zero and use zero factor principle given as:
So, we have:
