Answer:
All of them
Step-by-step explanation:
will be the function to calculate population every half year.
Further explanation:
The given formula is:

In the given formula, x represents the amount of time in years. So, in order to convert the given function for yearly calculation of population, to find the population every half year the time will be converted into half. This means that instead of x, x/2 will be used.
So the new function will be:

Answer:

Step-by-step explanation:
Given that,
Distance, d = 100 mile
Velocity of the winner, v = 120.1229 mph
We know that velocity of an object is equal to distance per unit time. Let t is the time. So,

Hence, 1.201 hour is taken by the winner.
Answer:
Option (C)
Step-by-step explanation:
The minimum value of x² is 0, and the maximum value is unbounded, so therefore, the maximum value of -x² is 0, and the minimum value is unbounded.
So, this means that adding 1 to this, the range matches with option C.
Radius=1.2
circuimsantece=2*3.14*1.2=76.36
circuimsantece of quarter=76,36/4=19.09
ratio=1/2
