V = 25^(3/2)

V = (√25)^3

V = 5 * 5 * 5 = 125 mm^3

Someone plzzzz help I don’t get this at all
Alex73 [517]

Answer:

Option B

Step-by-step explanation:

The slope of the line BC is,

\frac{ - 2 - 8}{7 - 3}

=  \frac{ - 10}{4}  =   - \frac{5}{2}

Since AD is altitude to BC, we can say AD is perpendicular to BC, so the slope of the line AD which is perpendicular line to BC will be,

\frac{2}{5}
