Answer: The answer would be f^-1 (x) = x/2 - 3/2
Answer:
Step-by-step explanation:
We want to study the fuel consumption of each car, i.e the amount of mile per gallon the cars will consume
Step one:
given data:
First car
distance covered= 41 1/2 = 41.5miles
amount of gallons= 1 1/4= 1.25gal
the miles per gallons= 41.5/1.25=33.2 miles per gallon
Second car
distance covered= 21 3/5= 21.6miles
amount of gallons=4/5= 0.8gal
the miles per gallons= 21.6/0.8=27 miles per gallon
1. Therefore the unit rate of
the first car = 33.2 miles per gallon
the second car=27 miles per gallon
2. the first car can travel a greater distance on 1 gallon of gasoline

Step-by-step explanation:
Comment
You are given values for the adjacent side of <x and the hypotenuse of a right triangle. This defines the Cosine of an angle
Equation
Cos(x) = a/c the way you have labeled it.
Givens
a = 9
c = 18
Solution
Cos(x) = a / c
Cos(x) = 9 / 18
cos(x) = 1/2
x = cos-1(1/2)
x = 60 degrees
Answer
x = 60
Answer:
60 ft²
Step-by-step explanation:
The reason being that you take the height of 8 and multiply it by the width of 15. 8×15=120 Then since a triangle is half of a square you would halve it. 120÷2=60 Which would then give you your answer.
