t is the time elapsed since the concentration was the A_=, this is the initial concentration.
For example, for A_0 = 250, k = -10 (it has to be negative because this is a decay function) and b = 24, the function will be:
F(t) = 250 * 24 ^ (- 10 t)
And so, given that t is the time, you have the relation that gives the value of the dependent variable as a function of the time t. If the unit is hours, you could make this table:
time, t in hours F(t) = 250 * 24 ^ ( -10t)
0 250 * 24 ^(0) = 250
0.01 250 * 24 ^ (- 10 * 0.01) ≈ 0.73
0.1 250 * 24 ^ (-10* 0.1) ≈ 0.042
1 250 * 24 ^ ( -10) ≈ 0.000000000000016
Answer:
30 kids are present
Step-by-step explanation:
Hey there champ! Basically you wanna divide 40 by 4, or the fraction 1/4 to get the number of kids absent which is 10. From here you subtract 10 from your og class size, 40 and get thirty! Have a great day :)
