Answer:

The co - ordinates of another end point is

(x,y) = (3, 12)

Step-by-step explanation:

<u>mid point formula:-</u>

Let $(x_{1} ,y_{1} ) and (x_{2} ,y_{2} )$ be any two end points

Mid point of two given points are

$(\frac{x_{1}+x_{2} }{2} , \frac{y_{1}+y_{2} }{2} )$

let (x,y ) be the another end point

given one end point is (5,-6)

now by using mid-point formula , we get

$(\frac{x+5}{2} , \frac{y-6}{2} )$ this is equating to given mid-point is M(4,3)

now $(\frac{x+5}{2} , \frac{y-6}{2} )=(4,3)$

simplify , we get

$\frac{x+5}{2} =4 and \frac{y-6}{2} =3$

cross multiplication and simplify

$x+5 = 8 and y-6=6$

x = 3 and y = 12

The another point is (x,y) = (3,12)

Exercise

svp [43]

By addition of all the exercise and substracting it from 1 hourJavier runs on treadmill on Monday is 0.40 hour.

Now According to the question javier completed 3 repetitions of each exercise so by multiplication time taken by javier to complete each exercise is as follow;

Squats = 0.8*3= 0.24 hour

Crunches = 0.03*3 = 0.09 hour

Lunges = 0.04*3 = 0.12 hour

curls = 0.05*3 = 0.15 hour

we can calculate total time taken to complete all exercise by Addition is,

0.24 + 0.09 + 0.12 + 0.15

0.60 hour

time taken on treadmill by javier;

1 hour - 0.60 hour

0.40 hour
