The 4 sides of a square are usually the same and the side length of squares 4 and 5 is a+b.
<h3>How to explain the square?</h3>
From the diagram, each side is called the side length. Therefore,
- Side length of square 4 = a + b
- Side length of square 5 = a + b
If the side lengths are equal that is (a + b), then the area which is the square of the side length will also be the same.

Test of a horizontal line.Suppose f is a function.F does not have an inverse if any horizontal line crosses the graph of f more than once.F does have an inverse if no horizontal line crosses the graph of f more than once
How do you calculate f's inverse?
- Finding a Function's Inverse
- Replace f(x) with y first, then.
- Every x must be replaced with a y, and vice versa.
- Solve the y-part of the equation from step two.
- In place of y, write f1(x) f 1 (x).
- Check that (ff1)(x)=x (f f f 1) (x) = x and (f1f)(x)=x (f f 1 f) (x) = x are both true to validate your work
f= {(1,2),(2,3),(3,5),(4,7)}
Dom(gof)=dom(f)={1,3,4}.
(gof)(1)=g{f(1)}=g(2)=3,
(gof)(3)=g{f(3)}=g(5)=1
(gof)(4)=g{f(4)}=g(1)
∴gof={(1,3),(3,1),(4,3)}.

Answer:
Distance between plane and airport is 134.4 miles.
Step-by-step explanation:
Given : An airplane leaves an airport and flies due west 150 miles and then 170 miles in the direction S 49.17°W.
To find : How far is the plane from the airport.
Solution : Distance from airport to west is 150 miles and then 170 miles in the direction south and angle form is S 49.17° W
Refer the attached picture for clearance.
Applying law of cosines
where a= 150 miles
b=170 miles
C= 49.17° angle in degree
c = distance between plane from the airport
Put values in the formula,
Therefore, Distance between plane and airport is 134.4 miles.
