PLEASE HELP!!! 1) In 2000, there were 109 million cell phone users. The number of cell phone users grew to 300 million in 2010.

a) Write an exponential model that represents the number of cell phone users, where t represents the number of years after 2000.

b) What is the average rate of change?

c) What would be the number of cell phone users in 2020?

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius

because parallelagram have all 4 angels the same size dependeing and a rectangle and square are oth parallelogram

find the vertical and horizontal asymptotes of the function f x = 5 x − 1 . to find the vertical asymptote, equate the denominator to zero and solve for . since the degree of the polynomial in the numerator is less than that of the denominator, the horizontal asymptote is .
