Answer:

Step-by-step explanation:
The function

gives the mass of the car as a function of the number of passengers in it.
And the function

gives the potential energy of the car as a function of the car's mass.
Now if the height of the ramp is 30 meters, we have


And to find the potential energy as a function of the number of passengers, we just substitute
into
to get:


which gives the potential energy as a function of the number of passengers.

Sorry, I'm not sure how to do Q7 :(
(1) For the parabola on the bottom row, the domain would be R and the range would be y ≥ -5
(2) For the hyperbola on the bottom row, the domain would be R\{3} (since there is an asymptote at x = 3) and the range would be R\{4} (since there is an asymptote at y = 4)
(3) For the square root function on the bottom row, the domain would be x ≥ -5 and the range would be (-∞, -2]
(4) For the function to the very right on the bottom row, the domain would be R and the range would be (-∞, -3]
Construction.
When construction workers need measurements that are fractions they need to be able to multiply/add/subtract/divide all of those different fractions and mixed numbers.
I hope I was able to help. Best of luck.
