Answer:
b ≈ 9.5, c ≈ 14.7
Step-by-step explanation:
Using the Sine rule in Δ ABC, that is
=
, substitute values
=
( cross- multiply )
b × sin23° = 7 × sin32° ( divide both sides by sin23° )
b = ≈ 9.5 ( to the nearest tenth )
Also
=
=
( cross- multiply )
c × sin23° = 7 × sin125° ( divide both sides by sin23° )
c = ≈ 14.7 ( to the nearest tenth )
The vertex form of the equation of a parabola is given by the following form:
In this exercise, we have the following equation:
From here, we can conclude that:
Since the leading coefficient is less than zero, the parabola open downward. So, the graph is shown below and the vertex has been indicated.
