On a number line, the directed line segment from q to s has endpoints q at –14 and s at 2. point r partitions the directed line segment from q to s in a 3: 5 ratio. which expression correctly uses the formula to find the location of point r?

Step-by-step explanation:            

We have been given that on a number line, the directed line segment from Q to S has endpoints Q at –14 and S at 2. Point R partitions the directed line segment from Q to S in a 3:5 ratio.

To write the expression which will find the location of R we will use section formula when a point P divides segment internally in ratio m:n.      

Now let us substitute our given values in section formula. Since number line is a one dimensional, therefore, its y-coordinate will be 0.

Therefore, the expression represents the formula to find the location of point R.  

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
