Triangle TRE has vertices T(3,6), R(-3,10), and E(-9,4). Find the coordinates of point M if line TM is a median of triangle TRE
Sergeeva-Olga [200]

Answer:

The coordinate of point M = (-6,7)

Explanation:

The Median of a triangle is a line segment from a vertex to the midpoint of the opposite side of a triangle.

Given: \triangle TRE has vertices T(3,6) , R(-3,10) and E(-9,4).

Here, line TM is a median of triangle TRE where M is the midpoint of RE.

The midpoint of  M of the line segment from R(-3,10)  to E(-9,4) is;

M = (\frac{-3+(-9)}{2}, \frac{10+4}{2}) = ( \frac{-12}{2}, \frac{14}{2} )=(-6,7)

Therefore, the coordinate of point M is, (-6,7).

A pharmaceutical company is testing two treatments, A and B, that are used to heal wounds.
denis-greek [22]
From the equation e^(-0.055x) = 2e^(-0.124x), we can first take the natural logarithm of both sides:
ln(e^(-0.055x)) = ln(2e^(-0.124x))
ln(e^(-0.055x)) = ln2+ln(e^(-0.124x))
Since ln(e^a) = a,
-0.055x = ln2 - 0.124x
0.069x = ln2
x = 10.05, or approximately 10 days
