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:
<h2>c = 220</h2>
Step-by-step explanation:
f(x) = cx + d
<u>For the first equation</u>
f(50) = 27,000
Substitute the value of x that's 50 into the expression
That's
50c + d = 27,000
<u>For the second equation</u>
f(100) = 38,000
Substitute the value of x that's 100 into the expression
We have
100c + d = 38,000
Subtract the first equation from the second one to eliminate d
That's
100c - 50c + d - d = 38,000 - 27,000
50c = 11,000
Divide both sides by 50
We have the final answer as
<h3>c = 220</h3>
