A. sum of rational and irrational and it ends up being rational
Let
x-------> the number of persons in the family
f(x)------> the function represent the cost of living
we know that
The domain of the function would only include positive integers, because the number of persons can not be negative or a fraction
The range of the function would only include positive numbers, because the cost can not be negative
therefore
<u>the answer is the option B</u>
The domain would only include positive integers.
Its right,vertical,and complementary.Hope this helps you a bunch!
To solve this, you'll need the interest formula: <span> P(1 + rt).
Then, plug in the numbers:
$500(1.08*3) = $1,620. That's your answer.</span>
Answer:
40 7th Graders
Step-by-step explanation:
First you add all of the students to get 25. Then you divide 100 by 25 to get 4 (this is gonna be your multiplier) now multiply each part of the ration by 4, and you get 60 6th graders and 40 7th graders :D.
