Directed line segment DE has endpoints D(-4,-2) and E(1,8). Point F divides DE such that DF:FE is 3:2What are the coordinates of

VMariaS [17]

The Solution.

The given points are

$D(-4,-2)\text{ and E(1,8)}$

The formula is

$\frac{mx_2+nx_1}{m+n}_{},\frac{my_2+ny_1}{m+n}$

In this case,

$m=3,n=2$

Therefore,

$\begin{gathered} (\frac{mx_2+nx_1}{m+n}_{},\frac{my_2+ny_1}{m+n}) \\ =(\frac{3(1)+_{}2(-4)_{}}{3+2}_{},\frac{3(8)_{}+2(-2)_{}}{3+2}) \\ \end{gathered}$ $=(\frac{3-8}{5},\frac{24-4}{5})=(-\frac{5}{5},\frac{20}{5})$ $=(-1,4)$

Hence, the correct answer is (-1, 4) (option 3)

What’s the answer to this problem , figure out the area and perimeter of this triangle

Zigmanuir [339]

Answer:

Area = 67.5 m²

Perimeter = 69 m

Step-by-step explanation:

<h3>Area of triangle:</h3>

b = 27 m & h = 5 m

$\sf \boxed{\text{\bf Area of triangle =$\dfrac{1}{2}bh$}}$

$\sf = \dfrac{1}{2}*27*5\\\\ =\dfrac{135}{2}\\\\= 67.5 \ m^2$

<h3>Perimeter of triangle:</h3>

Perimeter = sum of all sides

= 27 + 34 + 8

= 69 m
