Evaluate limit:<br> lim x approaches 0 e^(5x)-1-5x/x^2

rosijanka [135]

Lim as x approches 0 of (e^(5x) - 1 - 5x)/x^2 = lim as x approaches 0 of (5e^(5x) - 5)/2x = lim as x approaches 0 of 25e^(5x)/2 = 25/2 = 12.5

How long will it take to earn $1800 in interest if $6000 is invested at a 6% annual interest rate? how many years

Simora [160]

Answer:

Total interest will $1800 after 5 years.

Step-by-step explanation:

It is given that the principle amount is $6000.

Rate of interest rate is 6% per annum.

Total interest is $1800.

Formula for simple interest is

$I=\frac{P\times r\times t}{100}$

Where, P is principle, r is rate of interest in percent and t is time in years.

Substitute P=6000, r=6 and I=1800 in the above formula.

$1800=\frac{6000\times 6\times t}{100}$

$1800=\frac{36000t}{100}$

$1800=360t$

Divide both sides by 360.

$\frac{1800}{360}=t$

$5=t$

Therefore the total interest will $1800 after 5 years.

25 is what percent less than 35

mars1129 [50]

Difference between 25 and 35 = 35 -25
   = 10
Then
percentage by which 25 is less than 35 =(10/35) * 100
   = (2/7) * 100
   = 200/7
   = 28.57 percent
So 25 is 28.57% less than 35.This is the only clear way of solving these kind of problems. I hope you have understood the method used to solve this problem. Hopefully you can do such type of problems without needing any help.
