A business has a savings account that earns a 3% annual interest rate. At the end of 1996, the business had $4,000 in the account. The formula F
=
p
(
1
+
r
100
)
t
is used to determine the amount in the savings account.

F is the final amount,
p is the initial investment amount,
r is the annual interest rate, and
t is the time in years.
To the nearest dollar, how much did the business initially invest in 1991?
A.
$4,631

B.
$3,450

C.
$4,637

D.
$3,455

ok

step-by-step explanation:

yes. we do proportions in probabilities.

-232

step-by-step explanation:

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
