Answer:
The number they would count is 
Step-by-step explanation:
One mole is equal to 6.02214076x10^23 particles. In order to know the number counted by every human on Earth we simply multiply the number of humans times the count a "good counter" can achieve, 4x10^9x7.44x10^9 (for USA, change to 4x10^12 if you use de British English definition). Thus:
Using the function concept, it is found that this sequence is a function because it passes the vertical line test.
A function relates <u>each value of the input to one value of the output</u>, hence, option b is incorrect.
- On a graph, each value of x(horizontal axis) is mapped to a value of y(vertical axis), hence, a vertical line test can be applied to determine whether the relation is a function.
In this problem:
- For each day, there is only one output, which is her balance, hence, it passes the vertical line test.

A) the slope of distance vs time is speed:
i) from 09:00 to 09:11 it is increasing velocity positively and steadily by going away from the origin.
ii) the car speeds up by going away from the origin with constant velocity.
iii) the car does not have any movement stationary in 9m.
iv) it car is dropping speed, going toward the origin.
b) distance= 9m+6m=15m
c) i) slope= velocity= (9-0)/(24)= 3/8 km/h
ii) velocity = (6-4)/(19)=2/19 km/h
