Solving the following odes: (a) y" - 2y' - 3y = 3x + 1: (b) y" - 2y'--3y = e^x;

The answer to this is C. The dinosaur is about 5 feet taller than the person.  

Step-by-step explanation:

The reason why is because the human is 4 feet since it says that 1/2 inch on the scale is 2 feet and the human is 1 inch on the scale so the human is 4 feet.  

The dino is 8 feet since it goes to 2 inches on the scale which means 8 feet. The difference between 4 and 8 is 4, so 5 feet is the approximate for this problem.
