NEED ANSWER ASAP PLEASE. which situation could be modeled with an exponential function? 1) the amount of money is suzys piggy bank which she adds $10 to each week. 2) the amount of money in a certificate of deposit that gets 4% interest each year. 3) the amount of money in a savings account where $150 is deducted every month 4) the amount of money in Jaclyn's wallet increases and decreases by a different amount each week

Number 4 because then you could have a variable as an exponent hope this helps

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm

She should use 12/3 to measure
