Consider the function f(n) that models the number of man-hours required to manufacture (n) lawn mowers that are ready to ship. 1) which describes an appropriate domain for the function f(n)? a) all integers where n ≥ 0 b) all real numbers where n ≥ 0 c) all rational numbers where n > 0 eliminate d) all rational numbers where n ≥ 0 2) which function notation uses an appropriate domain for the function f(n)? a) f(−1) = 2 b) f(− 1 2 ) = 2 c) f( 1 2 ) = 2 d) f(1) = 2

where are the choices?

twenty-six miles over two gallons because the proportion for the original 13 miles to one gallon would be written 13/1 and, doing the same thing to the top and bottom, i multiplied by 2 and got 26/2

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
