Answer:
573.33
Step-by-step explanation:
599+14.33
= 573.33
(if rounding then its 600+14.33) = 614.33
It cost $156.40 because 20% of 195.50 is $39.10 so you subtract that from the 195.50.
The point of inflection is calculated by equating the second derivative to zero and determining x from there.
f"(x) = -x²2xsinx² + cosx²(2x) = 0
2xcosx² - 2x³sinx² = 0
2x (cosx² - xsinx²) = 0
2x = 0 ⇒ x = 0
cosx² - xsinx² = 0 ⇒ x = 3.82 (if you use shift+solve in your scientific calculator)
Thus, the function only has 1 point of inflection and it is at x = 0.
