find the difference between the simple interest and compound interest on 2500 for 2 years at 4% per annum , compound interest be

EastWind [94]

Answer:

Results are below.

Step-by-step explanation:

Giving the following information:

Principal (P)= $2,500

Interest rate= 4%

Number of periods= 2 years

First, we will determine the interest earned using the simple interest formula:

I= P*r*t

I= 2,500*0.04*2

I=$200

Now, using the compound interest formula:

I= [P*(1 + r)^t] - P

r= 0.04/2= 0.02 (semi annual interest rate)

t=2*2= 4 semesters

I= [2,500*(1.02^4)] - 2,500

I= $206.08

Find the inverse function for f(x) = cubic root sqrt x+2

dalvyx [7]

we are given

$f(x)=\sqrt[3]{x+2}$

Firstly , we set f(x)=y

$y=\sqrt[3]{x+2}$

now, we can switch x and y

$x=\sqrt[3]{y+2}$

now, we can solve for y

$x^3=(\sqrt[3]{y+2})^3$

$x^3=y+2$

$y=x^3-2$

so, our inverse function is

$f^{-1}(x)=x^3-2$ ............Answer
