suppose that you have the function f(x) = 9x^5 - 10x^4 - 2x. if f(c) = 1, what can you
conclude?
c is a root/zero of f(x).
c -1 is a factor of f(x).
c is not a root/zero of f(x).
x - 1 is a factor of f(x)

Step-by-step explanation:

The number c is not a root/zero of f(x).  If it were, then f(c) would = 0 (that is, the remainder would be zero.

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)
