Answer:
First option: 2
Step-by-step explanation:
Check each answer:
8 < x(7-x)
8 < 2(7-2)
8 < 2(5)
8 < 10
True
8 < x(7-x)
8 < 8(7-8)
8 < 8(-1)
8 < -8
False
8 < x(7-x)
8 < -1(7-(-1))
8 < -1(7+1)
8 < -1(8)
8 < -8
False
8 < x(7-x)
8 < 0(7-0)
8 < 0
False
Therefore, 2 is the only correct solution out of the given answer choices.

Answer: .81
27 * .03. let me know if you need further explanation
To determine the total distance traveled by an object in constant speed, just multiply the speed by the time. So, for the car, the total distance traveled is,
distance by car = (20 m/s)(5s) = 100 m
For decelerating object, the distance traveled is,
distance = Vt - (at^2)/2
For the truck,
distance by truck = (20 m/s)(10s) - (2m/s^2)((10s)^2)/2 = 100 m
Relatively, both have traveled the same distance.
