What is the percentage of growth? in the first quarter of 2010, u. s. advertisers spent $5.9 billion on online advertising. in the first quarter of 2011, they spent $7.3 billion. what is the percentage rate of growth? (round to one percentage place.)

24%

Percentage change is computed as follows. When it is positive, it represents growth or increase. When it is negative, it represents decrease or decline.

... percent change = ((new value) - (old value))/(old value) × 100%

... = (7.3 -5.9)/5.9 × 100%

... = 1.4/5.9 × 100%

... ≈ 0.2373 × 100%

... ≈ 24% . . . . . rounded to nearest whole percent

Since the time difference is 1 year, this is the annual growth rate.

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )
