Answer:
5.6 days
Step-by-step explanation:
We are given;
Initial Mass; N_o = 25 g
Mass at time(t); N_t = 25/2 = 12.5 (I divide by 2 because we are dealing with half life)
k = 0.1229
Formula is given as;
N_t = N_o•e^(-kt)
Plugging in the relevant values;
12.5 = 25 × e^(-0.1229t)
e^(-0.1229t) = 12.5/25
e^(-0.1229t) = 0.5
(-0.1229t) = In 0.5
-0.1229t = -0.6931
t = -0.6931/-0.1229
t = 5.6 days
Answer:
$19.70 OR $58.30
Step-by-step explanation:
I say either or because I can't see the answer choices.
Its either adding or subtracting from the one backpack we know is $39.00
If we know the difference between the two is 19.30
39.00+19.30 = 58.30
39.00-19.30= 19.70
See if either of those are available :) Hope this helps! :)
Mapping T'U'V'W' onto TUVW is just the backwards translations of TUVW to T'U'V'W'.
The translation (x + 3, y - 3) moves all x-coordinates 3 units to the right and all y-coordinates 3 units down.
So if we want to move the figure back to its original position, we do the opposite: move all x-coordinates 3 units to the <em>left</em> and y-coordinates 3 units <em>up</em>.
This is expressed as (x - 3, y + 3).
