Given f(x)=2x-x-4 and g(x)=-x-5, evaluate each of the following:
11. f(2)
12. f(-3)
13. : (-1).
14. 8(1/2)
15. fo.

a. the are of the rectangle is 18.25

b. 18.25 times two is 36.50

rae me : d

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)

13.46

step-by-step explanation:
