Answer:
The value of a is
The equation is
Step-by-step explanation:
we know that
The function of a vertical parabola written in vertex form is equal to
where
(h,k) is the vertex of the parabola
in this problem we have
substitute in the equation
Find the value of the coefficient a
Substitute the value of x and y of the point in the equation
The equation is equal to
----> is a vertical parabola open downward

Answer:
Step-by-step explanation:
The side given is opposite the given angle. We want to find both the hypotenuse and the adjacent side in the right triangle that models the geometry.
Sin = Opposite/Hypotenuse
sin(50°) = (230 ft)/h
h = (230 ft)/sin(50°) ≈ 300.24 ft
The length of the cable must be about 300.2 feet.
__
Tan = Opposite/Adjacent
tan(50°) = (230 ft)/d
d = (230 ft)/tan(50°) ≈ 192.99 ft
The cable must be anchored about 193.0 ft from the tower.
