Use synthetic divison to divide the polynomial p(x) = 4x3 − 5x2 + 6x − 7 by x − 2 and find
the quotient and remainder.

Step-by-step explanation:

To fine the number we put in the top corner, we need to set to 0 and solve for x.

That gives us 2, which we put in the top left corner.

Then, we write out all coefficients of every degree.

We bring the first value down, the multiply and bring down again, and so on.

This gives us our simplified equation. The remainder will go over the expression we were dividing by, or

-8

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
