The function f(x) = 3,189(1 + 0.05)x represents the amount of money in a savings account where x represents time in years. what does the 3,189 represent?

The answer is A: The initial amount of money placed in the savings account.

Step-by-step explanation: Obviously it would be the initial amount of money because 1.05 is only 1 dollar and 5 cents. So the obvious answer would be that 3,189 would be money. It wouldn't be  The amount of money in the savings account after one year Because it's nearly impossible to get a job that pays that low or save that low amount of money. It also wouldn't be The amount of money added to the savings account each year because you would have to be making good money for it to be that answer and the last answer is out of the question.

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
