A circle of radius r centered at the point (0,r) in the plane will intersect the y-axis at the origin and the point A=(0,2r), as pictured below. A line passes through the point A and the point C=(9r2,0) on the x-axis.

(a) The line through A and C has equation: y= ? x + ?(b) The x-coordinate of the point B is ? .(c) The y-coordinate of the point B is ? .(d) The limit as r->infty of the x-coordinate of B is (if your answer is infty , write infinity) ?(e) The limit as r->infty of the y-coordinate of B is (if your answer is infty , write infinity) ?

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

the answer is c hope this
