Which answer is a scientifically accurate description of velocity?

the hiker began hiking the park's five-mile north hiking trail at 8: 00 a. m. with plenty of daylight left to complete the hike before dark.

the motorcyclist traveled along a highway at 55 mph and reached the campsite in less than the two-hour estimated time.

walking south along the two-mile canyon trail generally takes less time than traveling the same trail north because walking south is all downhill.

the boat traveled from the dock north to the 200-meter marker in the bay in less than 5 minutes, giving the passengers several more hours to fish.

c. 7/3

step-by-step explanation:

a rational number is like pi- it is a repeating decimal.

a. is -1.8

b. 2.236068

c. 2.3333333333333333333

d.   is 3

i hope that ! =)

d. air pressure decreases as altitude increases.

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .
