The amount of money in an account may increase due to rising stock prices and decrease due to falling stock prices. marco is studying the change in the amount of money in two accounts, a and b, over time.

the amount f(x), in dollars, in account a after x years is represented by the function below:

f(x) = 10,125(1.83)x

part a: is the amount of money in account a increasing or decreasing and by what percentage per year? justify your answer. (5 points)

part b: the table below shows the amount g(r), in dollars, of money in account b after r years:

r (number of years) 1 2 3 4
g(r) (amount in dollars) 9,638 18,794.10 36,648.50 71,464.58

which account recorded a greater percentage change in amount of money over the previous year? justify your answer. (5 points)

center= (-2,0)

radius= sqrt2/2

step-by-step explanation:

range is infinite on both x and y axis positive and negative

step-by-step explanation:

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4
