Step-by-step explanation:
Sometimes. If the decimal never repeats itself and never ends, like pi, it is irrational. But if the decimal is .5 or .333333333333333... it either terminates (ends) or repeats itself forever, making it rational.

Step-by-step explanation:
To find g(f(4)), work from the inside out.
f(4) is 4^2+3, or 16+3, or 19. Now, we must find g(19).
This is 19+5/19. This is already a mixed number, though if you want an improper fraction solution, we have:
361/19+5/19
Which simplifies to:
366/19
Therefore, 366/19 is the answer.

Step-by-step explanation:
Notice that the red graph does not globally differ from the black graph: it would have been approximately the same one unless it had been displaced by 3 units up. Therefore, it was only the ordinate axis that underwent our change:

Answer:
Interest = $60.75
Amount = $510.75
Step-by-step explanation:
The formula for finding interest is;
Interest = Principal * Rate * Time
And here;
Principal = $450
Rate = 41/2% or 4.5%
Time = 3 years
Interest = 
Divided by 100 because of the percentage of the rate but here I made it 1000 because I moved the decimal point in the 4.5 forward once which means I have to add 0 to the denominator.
= 
= 
= $60.75
Now the amount is simply the Principal + Interest which will be;
= $450 + $60.75
= $510.75
