The point P(2, −1) lies on the curve y = 1/(1 − x). a. If Q is the point (x, 1/(1 − x)), use your calculator to find the slope of the secant line PQ (correct to six decimal places) for the following values of x:

1. 1.5
2. 1.9
3. 1.99
4. 1.999
5. 2.5
6. 2.1

b. Using the results of part (a), guess the value of the slope of the tangent line to the curve at P(2,-1).
c. Using the slope from part (b), find an equation of the tangent line to the curve at P(2,-1).

all three statements are true

step-by-step explanation:

a shipping fee of 5% is charged online with every item purchased online

first let's just take each option and calculate them based on this, to see if the answers matched

keith buys a 40 dollar book

40 x 0.05 = 2

therefore there will be a two dollar fee on keith's book

40 + 2 =42

the first statement is true

a chair costs $80

80 x 0.05 = 4

80 + 4 = 84

the second statement is true

george buys a 20 dollar calculator

20 x 0.05 = 1

20 + 1 = 21

the third statements are true

all three statements are true

well if he bought them at 5 cedis each sold them at 7 cedis each then he would make a profit of 2 cedis of each book. if in total he made 150 cedis profit that means he sold 75 books. he lost 12 books at the start so that means he originally bought a total of 82 books.
