X = number of days that have passed
448 = 14x
divide both sides by 14
32 = x
The answer is the last choice 2 1/2
Question 11= B
Question 13= C
I don't know how to do question 12
F(x)=-2e^x
x=3
f(3)=-2e^3
pemdas so exponents first
e^3
e=2.718281828454590
cube that
20.0855
now we have
-2 times 20.0855=-40.1711
answer should be -40.1711
(I see what you did wrong, if -6=-2 times e^3, divide -2, 3=e^3, maybe you just put -2 times 3 by mistake)
