The area of the circle is expressed in the formula A = pi r^2 while the formula of getting the circumference of the circle is C = 2pi *r. Trying to express A in terms of C, we square C first into C2 = 4pi^2r^2.  In this case, the answer to this problem therefore is A = C^2/4 pi. Answer is B

the function f(x) = 3,005(1+0.03)^x represents the amount of money in a savings account where x represents time in years. what d
Stolb23 [73]

Answer:

Option d. the initial amount of money placed in the savings account

Step-by-step explanation:

we have

f(x)=3,005(1+0.03)^{x}

This is a exponential function of the form

f(x)=a(1+r)^{x}

where

a is the initial value

r is the growth rate

(1+r) is the base

x is the number of years

f(x) is the amount of money in a savings account

In this problem we have

a=$3,005

r=0.03=3%

(1+r)=1.03

therefore

3,005 represent the initial value ( the amount of money for the value of x equal to zero)
