Quiz: Sket Sarah is paid $20 an hour at her new job. She wishes to graph her total pay T, as a function of the number of hours,
h. She wants to be sure her graph shows her pay for 10 and 20 hours of work. Select from the drop-down menus to correctly complete each statement. To best show this information, the scale for the T-axis of her graph should go from 0 to at least , and the h-axis of her graph should go from 0 to at least . Assessment navigation

1) Sket Sarah is paid $20 an hour at her new job. She wishes to graph her
total pay T, as a function of the number of hours, h.
=> T = 20h
2) She wants to be
sure her graph shows her pay for 10 and 20 hours of work.
Select from
the drop-down menus to correctly complete each statement. To best show
this information, the scale for the T-axis of her graph should go from 0
to at least:
Replace 20 hours in the function =>T = 20 * 20 = 400 => the T-axis of her graph should go from 0 to at least 400.
3), and the h-axis of her graph should go from 0 to at least .
h = 20 hours
=> The h-axis of her graph should go from 0 to at least 20. </span>
The solution for this problem is: The population is 500 times bigger since 8000/24 = 500. The population after t days is computed by:P(t) = P₀·4^(t/49) Solve for t: 8000 = 8·4^(t/49) 1000 = 4^(t/49) log₄(1000) = t/49t = 49log₄(1000) ≅ 244 days
