Multiplying a single row by a scalar scales the determinant by the same amount:

Since the interest is compounded, we will have to use the compound interest formula.
We Weill plug 7500 in for A, because that's the amount of money that we want to have at the end of some amount of time.
5000 will go in for P because that's the starting amount.
2.7% will be converted into a decimal percentage form. You can do this by dividing by 100, which you will get .027, and then plug that in for r, the rate.
Since the interest is compounded quarterly, n = 4.
After a bit of number crunching, you will get to the point where you have to solve for an exponent. You can easily do this by using the natural log ln(). One property of logarithm is that you can take the exponent and place it in front of the log. Now you can divide both sides to separate and solve for t.
Answer:
(A) Pi cannot be written as a ratio of integers even if it represents a different ratio.
Step-by-step explanation:
A rational number is can be expressed as the quotient of two integers. It can either be a number with or without a decimal part when converted to decimals.
C = 2r and D = 2r
C = D
Thus, =
= = 3.142857143...
Terrence was incorrect because Pi is an irrational number which cannot be represented by a simple fraction without approximation.
