Answer:
Total distance = 5.754 km
Step-by-step explanation:
Red lines of the right triangle show the layout of the race course.
Total length of the race course = Perimeter of the triangle
Perimeter of the triangle = Sum of the measures of all three sides
= 1.83 + 1.524 + 2.4
= 5.754 km
Therefore, total distance of the race course is 5.754 km.
Answer: 
Step-by-step explanation:
By definition the domain of an inverse function 
is the range of f(x) and the range of the inverse function is equal to the domain of the principal function f(x).
If you have a function 
, then to find the inverse function, follow these steps:
1. Make 
2. Solve for the variable "x":
3. Exchange the variable "x" with the variable "y":
4. Exchange "y" with
. Then the inverse function is:
I think it’s 55.6 square inches
Sorry if I’m wrong! :)
Answer:
5..(b)
Step-by-step explanation:
Pythagoras theorem states that
Hypotenuse(squared)=opposite(squared)+ adjacent(squared)
hypotenuse=?,opposite=3,adjacent=4
hyp(squared)=3(squared)+4(squared)
hyp(squared)=9+16
hyp(squared)=25
find the square root of both sides
hypotenuse=5
