Jerry plans on saving money for a trip by putting $1 in a savings account the first month and then adding enough to double the amount in the account each following month. Jerry plans on keeping up this saving pattern until he can no longer afford it. If the most jerry can afford to contribute in a month is $1200, for how many months will he be able to maintain his saving pattern

pi x^2

step-by-step explanation:

pi times x squared

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.

hey there : ) your answer would be a.

step-by-step explanation:

the answer on ed. is:

c. "the graph of f(x) has exactly two x-intercepts."

hope i could someone! : )
