Use the given map to find the coordinates of a point that lies on the directed line segment from c to d and partitions the segme

Lelechka [254]

Given:

The line segment is passing through the points (-9,-3) and (8,5),

Divide the segment in the ratio of 1:4.

Use the formula,

$\begin{gathered} (\frac{mx_2+nx_1}{m+n},\frac{my_2-ny_1}{m+n}) \\ (x_1,y_1)=(-9,-3) \\ (x_2,y_2)=(8,5) \\ m\colon n=1\colon4 \end{gathered}$

It gives,

$\begin{gathered} (\frac{1(8)+4(-9)}{1+4},\frac{1(5)+4(-3)}{1+4}) \\ (-\frac{28}{5},-\frac{7}{5}) \end{gathered}$

Answer:

$(-\frac{28}{5},-\frac{7}{5})$

Answer:

$\bar v = 60\,mph$

Step-by-step explanation:

The distance travelled by Lisa in the first four hours of her trip is:

$\Delta s = \left(50\,mph)\cdot (4\,h)$

$\Delta s = 200\,mi$

The distance remaining and her average speed are, respectively:

$\Delta s_{R} = 440\,mi - 200\,mi$

$\Delta s_{R} = 240\,mi$

$\bar v = \frac{240\,mi}{4\,h}$

$\bar v = 60\,mph$
