Based on the vertex form equation, the statements that are true are:
A.) the drone reaches its minimum 25 miles from the launch site
C.) at its minimum, the drone’s depth is -180 meters.
<h3>Rewriting the equation in vertex form</h3>
Given:
x = horizontal distance, in miles, from the launch site
d(x)= depth below the surface of the water, in meters.
Equation= 0.4x ²- 20x + 70
Hence
Rewritten the given equation ( 0.4x ²- 20x + 70) in vertex form will be:
Vertex form: d(x)=[2(x-25)²÷5] -180
Vertex= -180, 25
Minimum=-180 at x=25
Therefore the correct option is A, C.
