A store owner typically sells hats for $34.99. During a sale he prices them at $29.99. What is the approximate percent discount on a hat?

3, 12, 48, 384, 1536, 6144, 24576, 98304

step-by-step explanation:

just keep timing it by 4.

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13
