A family wants to save for college tuition for their daughter. What continuous yearly interest rate r% is needed in their saving

sergey [27]

Answer:

The continuous yearly interest is 22.5% per year.

Step-by-step explanation:

Continuous yearly interest:

Continuous yearly interest is defined as the sum of the interest comes from principle and the interest comes from interest.

The formula for continuous interest yearly is

$A=Pe^{rt}$

where A = The final amount =$110,000

P= principle =$4,700

r= rate of interest

t= time (in year)= 14 years

$\therefore 110,000= 4,700e^{r\times 14}$

$\Rightarrow e^{14r}= \frac{110,000}{4,700}$

Taking ln both sides

$\Rightarrow ln e^{14r}= ln(\frac{110,000}{4,700})$

$\Rightarrow {14r}= ln(\frac{1100}{47})$

$\Rightarrow r=\frac{ln( \frac{1100}{47})}{14}$

$\Rightarrow r = 0.225$ (approx)

The continuous yearly interest is 0.225 = 22.5% per year.

A student solved log4(2x – 12) = 3, as shown.

Mekhanik [1.2K]

1-When you have a the logarithm given in the problem above, you can solve it by using the correct properties for logaritms.
2- The students could solve it as below:
<span>log4(2x-12)=3
4^[</span> log4(2x-12)]=4^3
3- By definition a^log(x)=x, therefore,
2x-12=4^3
2x-12=64
4- Now, the students can solve for x:
x=38
The first step is incorrect, because the term on the right member must be 4^3.
