Galina-37 [17]

Answer:

The simplified expression is 2x + 1

Step-by-step explanation:

We are given the following in the question:

$e^{ln(2x+1)}$

We have to simplify this expression.

The logarithmic function is the inverse of the exponential function. Thus, we can write

$e^{ln(2x+1)}\\=2x + 1$

Thus, the simplified expression is 2x + 1

The population of a town is increasing at a rate of 6.2% per year. The city council believes they will have to add another eleme

kow [346]

Answer:

The correct solution is "4.6".

Step-by-step explanation:

Given:

Interest rate,

r = 6.2%

or,

= 0.062

Amount,

A = 100000

Principle,

P = 76000

As we know,

⇒ $A=P(1+\frac{r}{100} )^n$

On substituting the values, we get

⇒ $100000=76000(1+\frac{6.2}{100} )^n$

⇒ $(1+0.062)^n=\frac{100}{76}$

On taking log both sides, we get

⇒ $n \ log_e(1.062)=log_e(\frac{100}{76} )$

⇒ $n=\frac{ln(\frac{100}{76} )}{ln(1.062)}$

By putting the values of log, we get

⇒ $=4.5622$

or,

⇒ $=4.6$
