12! / 4!
= 1×2×3×4×5×6×7×8×9×10×11×12 / 1×2×3×4
= 5×6×7×8×9×10×11×12 = 19958400

Answer:
6.2
Step-by-step explanation:
We presume your "k-value" is the k in the exponential decay term ...
e^(-kt) . . . where t is the number of time units
This is 1/2 when ...
ln(1/2) = -kt
t = ln(1/2)/(-k) = ln(2)/k
t = 0.69315/0.1124 ≈ 6.2
The half life is about 6.2 time units.
-5/16
Our choices:-
A.-3/8
B.-11/12
C.-1/4
<span> D.-1/8

Let us get all of them with a LCD
-1*2 = -2
8*2 = 16
-2/16 is not bigger than -5/16
-11/12 is bigger than -5/16 because half of 16 is 8.
-1*4 = -4
4*4= 16
-4/16 is not bigger than -5/16
-1/8 is smaller than -5/16
Final answer: -11/12 is the only fraction bigger than -5/16
Six times twelve minus 4 equals forty-eight
Look at the graph at which x=3, then look and see what value y is and that will give you f(3).
