## voe PLEASE HELP!!! 3. An initial population of 175 quail increases at an annual rate of 22%. Write an exponential function to model the quail population. What will the approximate population be after 5 years? (1 point) ƒ(x) = 175(0.22)x; 473 ƒ(x) = (175 • 0.22)x; 84,587,005 ƒ(x) = 175(22)x; 901,885,600 ƒ(x) = 175(1.22)x; 473 4. Suppose you deposit \$5,000 in a savings account that earns 3% annual interest. If you make no other withdrawals or deposits, how many years will it take the account balance to reach at least \$6,000? (1 point) 10 years 6 years 7 years 4 years one year ago one year ago

1. NickR

P(t)=P0e^(rt) where P0 = P(0) = initial population, r = growth rate, sometimes also called Malthusian parameter, t = time.

2. NickR

i would say d for the first one

3. Valkarie70

the first one is A and the second one use the formula I=Prt I=5000*0.03*nuber of years and solve for x. and you get 7, 7 years would get you 5000 +1050 in interest bumping you over 6000\$

thanks that's what I had at first but wasn't sure I was right.

5. Valkarie70

so the answers are A C
