Answer:
The graph of the equation is shown in the picture attached below.
We can see w = 12 corresponds to the global maximum of the function, and for any w greater than 12 the value of A(w) decreases.
This means that for any value of the width greater than 12, the function cannot model the situation.
Making the equation only valid for
w ∈ [0,12]
15$ I believe, as we can disregard the two original books (they have been payed for) leaving her to buy 1 book and having seven dollars, however if she needs $8 more you simply need to add 8+7.
The answer is B. 9 - x. I hope this helps!
Answer:
12.5cm
Step-by-step explanation:
the figure appears to be a circle centered around point B, wherein segment CB is a radiai and segment DF is a diameter.
radiai(radius plural) are known to be 1/2 the length of diameters
(1/2) × 25 = 12.5
7/16 should be the answer
