Answer:
The 3rd and 4th option because their signs are positive and won't change a negative sign.
Step-by-step explanation:
Answer:
I would say the 32 oz of corn, because even though they are the same unit price, you get more in the 32 oz of corn.
Step-by-step explanation:
Well, you can set up this equation to find out the unit price for the 16 oz of corn:
$1.09 divided by 16 = $0.06
Same with the 32 oz of corn:
$1.89 divided by 32 = $0.06
That is the slope at f(1)
one way is to just take the derivitive
f'(x)=2x+(1/x)
for ti-89, do calc then derivitive then input "x^2+ln(x),x)" and click enter to get the derivitive
you would get f'(x)=2x+(1/x)
an easier way would be to have
click calc then differntiate then type x^2+ln(x),x)|x=1 then click enter
you get f'(1)=3
answer is 3
