The path of an underwater drone is modeled by quadratic function d, where x is the horizontal distance, in miles, from the launch site, and dis) is the depth below the surface of the water, in meters.
(a) = 0.452 - 205 + 70
Rewrite the equation in vertex form. Based on the vertex form equation, which statements are true?
The drone reaches its minimum 25 miles from the launch site.
At its minimum, the drone's depth is-180 meters.
At its minimum, the drone's depth is -430 meters,
The drone reaches its minimum 50 miles from the launch site.
At its minimum, the drone's depth is -70 meters.
The drone reaches its minimum 46 miles from the launch site,

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:

2b2t

explanation:

2b2t

the figure is a concave pentagon.

step-by-step explanation:

in mathematical context, a pentagon is a flat, two-dimensional closed shape (polygon) with 5 straight sides and 5 angles.

now a pentagon is said to be concave if one or more corners bend inwards and at least one of its angles is 180 degrees or more than 180 degrees.

in the given figure, we can see that we have a corner which is bending inwards and an angle which is clearly greater than 180°. therefore, it is a concave pentagon.
