Answer:

f'(0)=0

Step-by-step explanation:

Applying the chain rule

\frac{d}{dx} (f(-x))=-\frac{df}{dx}

Then it becomes

\frac{df}{dx} =-\frac{df}{dx}

In x=0

\frac{d[tex]f'(0)=-f'(0)\\f'(0)+f'(0)=0\\2f'(0)=0\\f}{dx} =-\frac{df}{dx}[/tex]

Then

f'(0)=0

A used book store buys a hardback book for $1.50 and then sells it for $5. Over time, the store sells the same number of books i
dybincka [34]

A used book store buys a hardback book for $1.50 and then sells it for $5. Over time, the store sells the same number of books it buys. The store manager can use the equation P(x)=5x−1.5x to determine the store's profit, P(x), where x is the number of books that the store sells. Which statement about the book store is true based on the profit equation?

Cost Price of book, C.P.=$1.50

Selling Price of book, S.P.=$5

PROFIT=S.P. -C.P.

So, Profit=$5-$1.50=$3.50

So, Profit=$3.50 on each book

Or, we are given P(x)= 5x-1.50x

Or, P(x)=3.50x

For each book, we must divide the profit P(x) by x, that is, number of books

\frac{P(x)}{x}=\frac{3.5x}{x}

\frac{P(x)}{x}=\frac{3.5*1}{1}

\frac{P(x)}{x}=3.5

So, Profit for each book sold is $3.50

Stephanie ran four laps around the school track in 7min and 30 sec how many sec per lap is that
tester [92]
Since each min is 60 seconds you multiply 60 by the number of minutes which is 7 and you get 420:

60x7=420 Then you add 30 seconds equaling 450 seconds total

Then you divide 450 by 4 since she ran 4 laps.

So, Stephanie ran 112.5 seconds per lap
