A population of bacteria can be modeled by P(t) = 22,000/1+1.2e^-kt. Where t is time in hours and k is constant. After 1 hour the bacteria population is 10,532. What is the value of k rounded to 4 decimal places? My son has already submitted his answer on an online exam, but the teacher didn't explain how they got the answer, and I'm not the greatest with math.

3: 2

step-by-step explanation:

shorter piece is 2: 3, so just reverse it, and you get 3: 2

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".

he will have 300 because he is really broke and 300 is in his imangine
