If you earned $240 interest on a loan of $600 at an interest rate of 5%, how many years was the loan for?

Answers

Answer:

The loan was for 8 years.

Step-by-step explanation:

It is stated that you earned $240 interest on a loan of $600 at an interest rate of 5%.

Find the duration time by using the formula

I = Pit

Here:

'I' is the interest'P' is the total principal loan'i' is the rate of interest per year't' is the total time in years

substituting I = $240, P = $600 and i = 5%

I = Pit

t = I / Pi

 = 240 / (0.05 × 600)

 = 240 / 30

t = 8 years

Therefore, the loan was for 8 years.

true or false: to find the second derivative of a function take the derivative of the furst derivative if the function

Answers

Answer:

True

Step-by-step explanation:

The second derivative of an implicit function can be found using sequential differentiation of the initial equation F(x,y)=0. At the first step, we get the first derivative in the form y′=f1(x,y). On the next step, we find the second derivative, which can be expressed in terms of the variables x and y as y′′=f2(x,y).
