The word gastric is derived from the Greek gaster, which means "stomach". The word cecum is from the Latin caecus, which means "blind." Using this information, explain why the term gastric cecum is a good name for the structure that the term describes.

Find the quotient using long division.

$$\frac{x^2 – 6x + 4}{x + 1}.$$

Integrate the expression.

$$\int x \sin ^{-1} x d x$$

A zoo is building a new large-cat exhibit. Part of the space will be used for lions and part for leopards. The exhibit will house eight large cats in all. Expenses for lion will be about $8000 per year, and expenses for a leopard will be about$6000 per year. Write an equation that can be used to find y, the yearly expenses for the eight cats in the exhibit when x of the cats are lions.

Solve the equation for y. 4x – 10y = 12

Sam has a theory about the average rate of change. Sam I can quickly estimate the average rate of change for interval that are above and below the $x-$axis because they add to zero for example at year 1. the profit is aboat $\$300,000$ and at year 2.25 the profit is about $-\$300,000$. Therefore. the average rate of change for the time interval $(1, 2.25)$ is approximately $\$0$

Describe the error in Sam's reasoning.
