What are the leading coefficient and degree of the polynomial?
18- 4x² + 23x

Below

Step-by-step explanation:

18 - 4x^2 + 23x is a second degree polynomial since the highest power is 2.

The leading coefficient is -4 since it's the number multiplied by x^2

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)

is should be y = 5x
