Compounds a and b are used in an experiment. the equation a=30,000(12)t represents the remaining amount of compound a, in milligrams, after t seconds. the table shows the remaining amount of compound b. time (sec) mg of b (1) 12,000 (2) 6,000 (3) 3,000 what is the positive difference in the initial amount of each compound? enter your answer in the box.

Hence, the difference in initial amount is:

6000 mg

       Time (sec)mg of B

          1                   12,000

          2                  6,000

          3                  3,000

Hence, the equation for B could be given as:

Now , the initial amount of compound A and B are the amount when t=0.

Hence,

A(0)=30000

Similarly,

B(0)=24000

Hence, the difference in the initial amount is given as:

Hence, the difference in initial amount is:

6000 mg

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

1; 35 is the ratio
