Answer: The correct option is
(C) 75.
Step-by-step explanation: Given that if a boat that travels 23 miles per hour in still water is traveling with a current that has a rate of 2 miles per hour.
We are to find the distance that the boat will travel in 3 hours.
The actual speed of the boat
= speed of the boat in still water + speed of the current.
So, the speed with which the boat is travelling
= 23+2
= 25 miles per hour.
That is, in 1 hour, distance traveled by the boat = 25 miles.
Therefore, in 3 hours, the distance traveled by the boat is given by
Thus, the required distance that the boat will travel in 3 hours is 75 miles.
Option (C) is CORRECT.

Answer:
Step-by-step explanation:
The axis of symmetry can be calculated using the formula:
First we must determine a and b from the quadratic: . This is in standard form, with the highest power first in descending order.
Standard form is also:
If we compare this to the quadratic given, we can conclude that:
Substitute the values for a and b into the formula.
Multiply in the denominator.
Divide.
This can also be determined from the graph. It is the x-coordinate of the vertex or the maximum/minimum. It divides the quadratic into 2 symmetrical halves.
