The publisher of a recently released nonfiction book expects that over the first 20 months after its release, the monthly profit

wolverine [178]

Answer:

(a) $\frac{dP}{dt}=\frac{4800-1600t-240t^2}{(t^2+20)^2}$

(b)P'(5)=-($4.54) Thousand

(c)P'(11)=-($2.10) Thousand

(d)The fifth Month

Step-by-step explanation:

Given the monthly profit model:

$P(t)=\frac{240t-40t^2}{t^2+20}$

(a)We want to derive a model that gives the Marginal Profit, P' of the book.

We differentiate

$P(t)=\frac{240t-40t^2}{t^2+20}$ using quotient rule.

$\frac{dP}{dt}=\frac{(t^2+20)(240-80t)-(240t-40t^2)(2t)}{(t^2+20)^2}$

Simplifying

$\frac{dP}{dt}=\frac{4800-1600t-240t^2}{(t^2+20)^2}$

We have derived a model for the marginal profit.

(b) After 5 months, at t=5

Marginal Profit=P'(5)

$\frac{dP}{dt}=\frac{4800-1600t-240t^2}{(t^2+20)^2}$

$P^{'}(5)=\frac{4800-1600(5)-240(5)^2}{(5^2+20)^2}$

=-($4.54) Thousand of dollars

(c)Marginal Profit 11 Months after book release

$P^{'}(11)=\frac{4800-1600(11)-240(11)^2}{(11^2+20)^2}$

=-($2.10) Thousand of dollars

(d) Since the marginal profit at t=5 is negative, after the 5th Month, the profit starts to experience a steady decrease.

HELPPPP!!!! ONLY NUMBER 24 AND 25 PLEASEEEE

Alex_Xolod [135]

Though I don't know #24, I know #25.

Take 15% of 31.77 and you should get 4.7655.
Now add 31.77 with 4.7655 and you should get 36.5355.
Round 36.5355 to the nearest hundredth.

Your final answer is $36.54

Vanessa buys a strip of 25 postage stamps the stamps is 21 7/8 inches long how long is it after Vanessa uses on stamp

zloy xaker [14]

To get the answer we have to multiply 25 times 21 7/8. To do that we have to transform 21 7/8 into improper fraction and thn multiply 25 times numerator.
$21 \frac{7}{8}= \frac{21*8+7}{8}= \frac{175}{8}$
$\frac{175}{8}*25 = \frac{175*25}{8}= \frac{4375}{8}=546 \frac{x}{y} \frac{7}{8}$ - its the answer
