Explain why the amount of money in the account at the end of t years is given by the formula:

nevsk [136]

Answer:

Step-by-step explanation:

The initial amount invested is P0

Say it is compounded periodically either quarterly or monthly or semi annually with interest r%

If for a period interest is r%

Then after first period principal = principal+simple interest

= $P_{0}+\frac{P_{0}r }{n}$

where n is the no of times in a year it is compounded. n = 4 if quarterly, 12 if annually, etc

At the end of II period we have

Principal = $P_{0}+\frac{P_{0}r }{n}$

So for interest again the process is repeated

Thus we repeat this nt times which result in power with nt

Hence the formula

Solve for x. 2/x^2−4 − 1/x+2=3/x−2 −32 −12 23 2

Alex Ar [27]

Answer:

x = -1/2.

Step-by-step explanation:

x^2 - 4 = (x - 2)(x + 2) so if we multiply each term by x^2 -4 we get:

2 - 1(x - 2) = 3(x + 2)

2 - x + 2 = 3x + 6

2 + 2 - 6 = 3x + x

4x = -2

x = -1/2.
