Answer:
between 7 and 8
Step-by-step explanation:
7 squared is 49
8 squared is 64
49 < 52 < 64
The independent variable is time, which varies from 0 to 0.5, so domain = [0,0.5].
The distance travelled is the dependent variable, varying from 0 to (1/2)80=40 km. The range is therefore [0,40].
Note: in interval notation, a square bracket means that the value is included in the interval.

Answer:
Step-by-step explanation:
You should indicate which type of expression are you expecting.
But intuitively, x^2 + 16 = x^4 + 4^2 = (x+4)^2 - 8x
The answer is 2 1/2 because you take the number of steps which is 13,200 and divide it by how many feet are in a mile which is 5,280.
