Which choice could NOT be modeled by an exponential function? he amount, y, of radioactive material remaining after x years when decay occurs at a rate of 30% each year the monthly cost, y, to use a cell phone for x minutes at a rate of 4 cents per minute the amount of money, y, in an account after x years earning 4% interest compounded annually the height, y, of a ball after bouncing x times, if each bounce reaches half of the previous height

i think the answer is b

she will sew have sewn five dresses   and be 1/3 done with the sixth one in an hour.

step-by-step explanation:

3/4 of an hour=45 mins

lucy makes 1 dress per 11.25 minutes

45 mins+11.25 mins=56.25 mins

60 mins- 56.25 mins=3.75 mins

3.75 mins is 1/3 of of 11.25 mins

therefore she the other 1/3 would be part of the hour and she will have sewn 5 dresses and begun the sixth.

contact me if you have any questions you are welcome.
