soldier1979 [14.2K]

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.
