The compound interest formula is : 
where, A= Future value including the interest,
P= Principle amount, r= rate of interest in decimal form,
t= number of years and n= number of compounding in a year
Here, in this problem P= $ 51,123.21 , t= 20 years and 2 months
So, t= 20 + (2/12) years
t= 20 + 0.17 = 20.17 years
As the amount is compounded daily, so n= (12×30)= 360 [Using the traditional Banker’s rule of 30 days per month]
Thus, 
When the interest rate is given, then we can use this equation for finding the future value.
Step-by-step explanation:
rational expression can be written as a ratio and all neutral numbers xan be written as a ratio
root of 26 is irrational because it can't be written as a ratio since its not a whole number.
Answer:
10 divided by 2 =5
Step-by-step explanation:
As the intervals are of 2.. and they extend all over from 0 to 10.. hence dividing it..
The first blank should be -5. The second should be -10. The third one should 10, if it’s talking about the opposite of -10.
