Consider the coordinate plane:
1. The origin is the point where Sharon and Jacob started - (0,0).
2. North - positive y-direction, south - negetive y-direction.
3. East - positive x-direction, west - negative x-direction.
Then,
- if Jacob walked 3 m north and then 4 m west, the point where he is now has coordinates (-4,3);
- if Sharon walked 5 m south and 12 m east, the point where she is now has coordinates (12,-5).
The distance between two points with coordinates 
and 
can be calculated using formula
Therefore, the distance between Jacob and Sharon is
Answer:
<u>32m^2</u>
Step-by-step explanation:
32m^2
8*4 = <u>32</u>
Have a nice day! :-)
<span>(2 + 5i)(2 + i)
= 4 + 10i + 2i + 5i^2
= 4 + 12i + 5i^2</span>
Answer:
m<F = 80 degrees
Step-by-step explanation:
Since line DF and line FE are congruent you know that the triangle is isosceles so you know that <D and <E are equal.
50+50=100
180-100=80
Answer:
a. The distance from the center to either vertex
Step-by-step explanation:
The distance from the center to a vertex is the fixed value <em>a</em>. The values of <em>a</em> and <em>c</em> will vary from one ellipse to another, but they are fixed for any given ellipse.
I hope this helps you out alot, and as always, I am joyous to assist anyone at any time.
