In this scenario, we start with the following expression:
The first step involves evaluating the quadratic component.
Next, we have:
The following step is to subtract the two resultant values:
It is clear that the outcome of this operation is a negative value.
Answer:
The expression results in:
Answer:
The function decreases across all real numbers x where x < 1.5.
Step-by-step explanation:
We have
This represents an upward-opening vertical parabola
The vertex denotes a minimum point
The vertex is located at (1.5,-6.25)
We know that
The function is decreasing within the interval ----> (-∞, 1.5) x < 1.5
This means----> the function is continuously decreasing for all real x values under 1.5
Conversely, the function is increasing within the interval ----> (1.5, ∞) x> 1.5
Thus, for all real x values greater than 1.5, the function is increasing
Check the attached figure for further clarification
Therefore
The true statement is
The function decreases across all real numbers x where x < 1.5.
The maximum distance visible on Earth is calculated using the formula
= your initial height and
= your secondary height
In this case, represents the height of the periscope and
denotes the height of the ship, leading us to a distance of 832.45553203368 feet. However, rounding to the nearest mile yields the answer as
If there are any discrepancies, please inform me and I will recalculate!
