2x² – 5x + 3 = m(x)
Answer:
Step-by-step explanation:
For quadratic ax² +bx +c, the axis of symmetry is x = -b/(2a). For your function, a=2, b=-5, c=3 and the axis of symmetry is ...
x = -(-5)/(2(2)) = 5/4 = 1.25
The vertex is on the axis of symmetry. The y-value there is ...
m(5/4) = (2(5/4) -5)(5/4) +3 = (-5/2)(5/4) +3 = -25/8 +24/8 = -1/8
The vertex is (5/4, -1/8).
The axis of symmetry is x = 5/4.
The leading coefficient is positive, so the parabola opens upward. The vertex is a minimum.
The minimum is -1/8.
The function is defined for all values of x, so ...
the domain is all real numbers.
Values of y can only be -1/8 or greater, so ...
the range is y ≥ -1/8.

Step-by-step explanation:
Let's say the position of the fire is point C.
Bearings are measured from the north-south line. So ∠BAC = 55°, and ∠ABC = 60°.
Since angles of a triangle add up to 180°, ∠ACB = 65°.
Using law of sine:
190 / sin 65° = a / sin 60° = b / sin 55°
Solving:
a = 181.6
b = 171.7
Station A is 181.6 miles from the fire and station B is 171.7 miles from the fire.
