For Exercises 21–26, use the master theorem to determine an order-of-magnitude expression for the work done. 21. S(n) = 2S a n 4 b + n2 22. S(n) = 4S a n 3 b + n 23. S(n) = 4S a n 4 b + n 24. S(n) = 4S a n 2 b + n2 25. S(n) = 3S a n 3 b + "n 26. S(n) = 2S a n 2 b + n3

439400

step-by-step explanation:

130^2 = 16900

16900*26 = 439400

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
