Emily draws point C on the line segment so that the ratio of AC to CB is 3 to 1. What are the coordinates of Point C? a. (-2,2.5)

b.(-1,2)

c.(3,0)

d.(4,-0.5)

d.(4,-0.5)

Step-by-step explanation:

We are given that the ratio of AC to CB

AC:CB=3:1

From given figure

The coordinates of A are (-5,4)

The coordinates of B are (7,-2)

We have to find the coordinates of C

Section formula:

Using the formula

The coordinate of point C are

Hence, the coordinate of point C are (4,-0.5)

Option d is true.

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m

no i do not : ( what is it?
