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:
B
Step-by-step explanation:
all you need to do is add 5 to the y for example ( -5, 5) add 5 to the (x,5) to make ( -5,10). As you can see only the y value is shifting, not the x value, that's why you need to add 5 to all the y values.
So the answer here is B.
Answer:
(-3, -4)
Step-by-step explanation:
The solution is where the two lines intersect. Therefore, the x-coordinate is -3, and the y-coordinate is -4.
Another way to solve this would be to set the to equations equal to each other, so 2x+2 = -4. Therefore, 2x = -6, and x = -3. And from the second equation, y = -4.
In the Figure below is shown the graph of this function. We have the following function:
The 
occurs when 
, so:
Therefore, the is the given by the point:
From the figure we have three 
:
So, the occur when 
. Thus, proving this:
