Quadratic:

a.

c.

e.

i.

j.

Neither:

f.

h.

Linear:

b.

d.

g.

Step-by-step explanation:

Linear equations are generally expressed in the form y = mx + b - the highest exponent of x is one.

Quadratics are expressed as y = ax^2 + bx + c - the highest exponent of x is two.

Any equation with an exponent of x higher than two is neither linear nor quadratic, but instead cubic or higher.  Therefore we can simply sort these equations by the highest exponent of x present after simplifying.

answer

point o.

step-by-step explanation:

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)
