3. Since January 1980, the population, P, of the city of Brownville has increased closely modeling the function, P(y) = 720500(1.022) where y is the number of years since January 1980.
(b) By what percent is the population increasing?
a) Explain what the numbers 720,500 and
1.022 represent in this model.
Please help me

720,500 is the starting population of Brownville in Jan 1980 1.022 is the growth factor. The population grows 2.2% each year b) 1548800 = 720500*(1.022)^x 1548800/720500 = = (1.022)^x Taking log both sides...

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.

cause it equals more
