Answer:
True
Step-by-step explanation:
In algebra, a quadratic function, a quadratic polynomial, a polynomial of degree 2, or simply a quadratic, is a polynomial function with one or more variables in which the highest-degree term is of the second degree
divide the shape into 2 triangles and 1 rectangle
left triangle :
hypotenuse = 7 in
height = 6 in
base = x
find the base using pythagoras theorem
x = √( 7² - 6² )
x = √13
x = 3.6 in
find it's area
6 × 3.6 ÷ 2 = 10.8
right triangle :
hypotenuse = 9 in
height = 6 in
base = x
find the base using pythagoras theorem
x = √( 9² - 6² )
x = √45
x = 6.7 in
find area
9 × 6.7 ÷ 2 = 30.15 in
middle rectangle :
16 in - left tri. base = base
16 - 3.6 = 12.4
find area
6 × 12.4 = 74.4
sum of the area
10.8 + 30.15 + 74.4 = 115.35
The direction of Beatriz relative to the <em>starting</em> point of her trip is approximately 
.
<h3>How to find the position of Beatriz relative to the starting point of her trip</h3>
After a careful reading of the statement, we find that <em>final</em> position (
) by the end of the second day is found by means of this vector sum:
(1)
Where:
- Vector distance of the first day relative to starting point, in kilometers. 
- Vector distance of the second day relative to the final point of , in kilometers.
If we know that 
and 
, then final position of Beatriz relative to origin is:
![\vec r = (48.670, -314.159)\,[km]](https://tex.z-dn.net/?f=%5Cvec%20r%20%3D%20%2848.670%2C%20-314.159%29%5C%2C%5Bkm%5D)
And the direction <em>relative to</em> the <em>starting</em> point (
), in degrees, is found by following inverse <em>trigonometric</em> relation:
(2)
If we know that 
and 
, then the direction of Beatriz relative to the starting point of her trip is:
The direction of Beatriz relative to the <em>starting</em> point of her trip is approximately .
