Consider the following expression: (1 + x)^n. A) Use the Binomial Theorem to find the first four terms of this polynomial.

B) Why is 1 + nx a good approximation of this expression when x is less than 1?

table 3 represents a direct variation function. : )

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c

answer is a.

13.268

hope you get it right.
