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.

Answer:
Step-by-step explanation:
Upon factoring all terms we are left with the product of
[(x-4)(x+6)(x-6)]/[5(x-6)(3x+5)(x-4)]
The (x-4)s and (x-6)s cancel out and we are left with
(x+6)/(5(3x+5)) which is also equal to
(x+6)/(15x+25)

Step-by-step explanation:
Expand: 4.2×5.1×x+4.2×6.8
4.2×5.1×x to (21.42)x
Simplify: 21.42x+4.2×6.8
4.2×6.8 = 28.5628.56
21.42x+28.56
Answer:
9 hours
Step-by-step explanation:
If there's 4 people, they each need 1.5h So you multiply 1.5 by 6 and that's how you find how long it takes for 1 person.
