A bank account balance, b, for an account
starting with s dollars, earning an annual interest
rate, r, and left untouched for n years can be
calculated as (an exponential
growth formula). Find a bank account balance
to the nearest dollar, if the account starts with
$100, has an annual rate of 4%, and the money
is left in the account for 12 years.

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

x/3-10=8

x/3=18

x=48

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
