Find the coordinate that divides the directed line segment from A(-2,-4) to B(8,1) in the ratio of 2 to 3
Answers
we have that A(-2,-4) B(8,1)
let M-------> the coordinate that divides the directed line segment from A to B in the ratio of 2 to 3
we know that
A--------------M----------------------B 2 3 distance AM is equal to (2/5) AB distance MB is equal to (3/5) AB so
step 1 find the x coordinate of point M Mx=Ax+(2/5)*dABx where Mx is the x coordinate of point M Ax is the x coordinate of point A dABx is the distance AB in the x coordinate Ax=-2 dABx=(8+2)=10 Mx=-2+(2/5)*10-----> Mx=2
step 2 find the y coordinate of point M My=Ay+(2/5)*dABy where My is the y coordinate of point M Ay is the y coordinate of point A dABy is the distance AB in the y coordinate Ay=-4 dABy=(1+4)=5 Mx=-4+(2/5)*5-----> My=-2
the coordinates of point M is (2,-2)
see the attached figure

Answers
The answer is B i think. i think you forgot the plus sign on B.

Round 19.98 to the nearest whole number
Answers
19.98 rounded to the nearest whole number is 20. In the number 19, 9 round the 1 to a 2 and the 9 becomes a 0 because of the 9 behind the decimal. OR You could think of a percent being 100. 98 is only 2 numbers away from 100 and thus you can round 19 up to 20.
Hope this helps! (:
The answer is 20. To make problems like this easier for you to understand, if the number is greater than 5 round up. If the number is 4 or less, round down. I hope you get what I am saying.
