The solution to show the absolute value inequality is (-3,-2)
<h3>What is absolute inequality?</h3>An absolute value inequality is an expression with absolute functions as well as inequality signs
Interval = -3 to 2
The intervals are represented with open parenthesis, which shows that -3 and 2 are excluded values of the inequality.
So, we have:
-3 < x < 2
As an interval notation,
(-3,-2)
Hence, the solution to the absolute value inequality is (-3,-2)

Answer:
Rui will reach his lowest altitude after diving for 10 seconds
Step-by-step explanation:
In the quadratic equation y = ax² + bx + c, the coordinates of the lowest or the highest point is (h, k), where
- h =
and k = y at x = h
In the given question
∵ d(x) = x² - 10 x
∵ d represents his altitude in meters after x seconds
→ Compare it with the form above to find a and b
∴ a = and b = -10
∵ h =
→ Substitute the values of a and b in the rule to find h
∴ h = = 10
∴ h = 10
∵ h is the x-coordinate of the lowest point
∴ The time of the lowest altitude is 10 seconds
∴ Rui will reach his lowest altitude after diving for 10 seconds
