Dimas [21]

The answer is "562.432"

Step-by-step explanation:

Given:

P= 500\\\\r= 4\%\\\\n= 3  \ years\\\\\text{frequency of conversion}\ (A)=?

Using formula:

\to A=P(1+r)^n

       = 500(1+4\%)^3\\\\= 500(1+\frac{4}{100})^3\\\\= 500(1.04)^3\\\\=500 \times 1.124864\\\\= 562.432

Prove that |a| < b if and only if -b < a < b
asambeis [7]

Answer:

Since,

|x|=\left\{\begin{matrix}x &\text{ if } x \geq 0 \\ -x &\text{ if } x < 0\end{matrix}\right.

Here, the given equation is,

|a| < b

Case 1 : if a ≥ 0,

|a| < b ⇒ a < b

Case 2 : If a < 0,

|a| < b ⇒ -a < b ⇒ a > - b

( Since, when we multiply both sides of inequality by negative number then the sign of inequality is reversed. )

|a| < b ⇒ a < b or a > - b ⇒ -b < a < b

Conversely,

If -b < a < b

⇒ a < b or a > - b

⇒ a < b or -a <  b

⇒ |a| < b

Hence, proved..
