Answer:
A
Step-by-step explanation:
Distinguish exact and uncertain numbers; Correctly represent uncertainty in quantities using significant figures.
Answer:
So in exponential form
will be equivalent to 
Step-by-step explanation:
We have given the expression in radical form as 
We have to find its equivalent in exponential form
We know that if any fraction is in radical form then if we write this in exponential form then in exponential form the exponent come inverse of its number
So
can be written as 
So in exponential form
will be equivalent to 
Solution:
we are given that
Dan borrowed $750.00(=P) from his brother who is charging him 8% (=r)simple interest.
Dan pays his brother back in 6 months(=t).
we have been asked to find- how much does he have to pay back including the interest?
As we know that

Substitute the values we get

Hence net payable amount is 750+30=$780
Answer:
50Hz x .10m = 5 m/s
20 m/s divided by .50m = 40Hz
80 m/s divided by .20m = 400Hz
120 m/s divided by .40m = 300Hz
340 m/s divided by 440Hz = .77m
X = (Y - 5) / 6 so X is that
