Answer:
Mr. Lopez delivers 1.5 tons of dog food to the animal shelter.
Step-by-step explanation:
Mr Lopez picks up 2 pallets of dog food to deliver to the animal shelter. Each pallet contains 40 bags of dog food, and the dog food weighs 37 1/2 pounds pet bag.
The weight of 1 bag of dog food = 
The weight of 40 bags of dog food = 
Each pallet weighs = 1500 pounds

We know that 2000 pounds = 1 ton

Hence, Mr. Lopez delivers 1.5 tons of dog food to the animal shelter.
Answer:
Step-by-step explanation:
d(t)=-2t^2+9t+18
calculate the derivate : f'(t) = - 4t+9
f'(t) = 0 : - 4t+9= 0 so t = 9/4
the maximum value is f(9/4) = ....... continue
The answer is C. Would you like me to explain how I got that?
