Find the exact coordinates of point E.

Answer:

is the correct answer.

Step-by-step explanation:

We are given that co-ordinates of D is (-3,8) and F is (5,2).

For finding a point E on the line segment DF dividing it in a ratio 4:1, we can use segment formula.

x = \dfrac{mx_{2}+nx_{1}}{m+n}\\y = \dfrac{my_{2}+ny_{1}}{m+n}

Where (x,y) is the co-ordinate of the point which  

divides the line segment joining the points and in the ratio m:n.

As per the given values  

x_{1} = -3\\x_{2} = 5\\y_{1} = 8\\y_{2} = 2

Putting the given values in above formula :

x-co-ordinate of F:

x = \dfrac{5 \times 4 + (-3 \times 1)}{4+1}\\\Rightarrow \dfrac{17}{5}\\\Rightarrow x = 3.4

y-co-ordinate of F:

y = \dfrac{4 \times 2 + 1 \times 8}{4+1}\\\Rightarrow \dfrac{16}{5}\\\Rightarrow y = 3.2

So, answer is E(3.4,3.2).

The answer would be 60

The first think you would need to do would simply 144. Which would be 12.

Then you are going to want to multiply-5 by 12.
Which would be 60.
With 12 as a positive number, being greater or to than 60 then will become a positive.
