Hi!
<em>To calculate the rate of change between days 4 and 6, we simply take those points, (4, 1503) and (6, 2196) and use the equation in the picture below:</em>
<em />
Now, when we plug it in the equation, it looks like this:

Therefore, your answer is 346.5 or, rounded, 347.
<em><u>Meaning, your answer is C</u></em>

Hope this helps and have a great day! :D
Answer:
8
Step-by-step explanation:
Divide by 2 and find out.
4/9 / 2
Multiply by its reciprocal:
4/9 * 1/2
Multiply the numerators and denominators together:
4/18
4/18 does not equal 8/18, so 4/9 isn't half of 8/18.
So, when we're tasked with things like this, rewriting everything in terms of sine and cosine and combining fractions often trivializes things, so doing just that gives us:

So out expression is 1/cos(x).
Answer:
Step-by-step explanation:
Juan has 20 books to sell. He sells the books for $15 each.
The range of the function is the set of all possible values of the dependent variable. The dependent variable here is the amount of money that is made and this amount depends on
the number of books, x sold
The amount of money Juan makes from selling books is represented by a fucntion. f(x)=15x
The maximum amount that can be made from 20 books at a rate of $15 each would be 20×15 = $300
The minimum amount that fan be made is $0 and this is when no book is sold. Let y = f(x). So the range is
0 lesser than or equal to y lesser than or equal to 300
