Question

Problem 1b

Answer 1

Given information

Consider, 

t (min)	5	10	15	20	25	30
V (gal)	694	444	250	111	28	0

 

From the part (a) assuming the two secant lines are .

Then find the average slope .

Step-by-step explanation

Step 1.

Consider,

The part (a) assuming the two secant lines are  .

Let us estimate the slope of tangent P by averaging the two secant lines.

 

 

Thus, the average slope is .
