The annual net income of a company for the period 2007–2011 could be approximated by P(t) = 1.6t2 − 11t + 44 billion dollars (2
son4ous [18]

Answer:

P'(t) = 3.2 t -11

And we can set equal this derivate to 0 in order to find the critical point and we got:

3.2 t-11= 0

t = \frac{11}{3.2}= 3.4375

And we can calculate the second derivate and we got:

P''(t) = 3.2 >0

So then w can conclude that the value of t = 3.4375 represent the minimum value for the function and we can replace in the original function and we got:

P(3.4375) = 1.6(3.4375)^2 - (11*3.4375) +44 = 25.094

So then the minimum annual income occurs at t = 3.43 (between 2008 and 2009) and the value is 25.094

Step-by-step explanation:

For this case we have the following function:

P(t) = 1.6 t^2 -11t +44

Where P represent the annual net income for the period 2007-2011 and 2 \leq t \leq 7

And t represent the time in years since the start of 2005

In order to find the lowet income we need to use the derivate, given by:

P'(t) = 3.2 t -11

And we can set equal this derivate to 0 in order to find the critical point and we got:

3.2 t-11= 0

t = \frac{11}{3.2}= 3.4375

And we can calculate the second derivate and we got:

P''(t) = 3.2 >0

So then w can conclude that the value of t = 3.4375 represent the minimum value for the function and we can replace in the original function and we got:

P(3.4375) = 1.6(3.4375)^2 - (11*3.4375) +44 = 25.094

So then the minimum annual income occurs at t = 3.43 (between 2008 and 2009) and the value is 25.094

One pound of ground beef costs $3.99. Five pounds of ground beef costs $17.45. How much cheaper is the ground beef per pound if
xxTIMURxx [149]

Step-by-step explanation:

Ok, so, to find this, remember- to find the true price of an item, remember the equation (PRICE DIVIDED BY QUANTITY), this will give you true price. So, for the individual, its $3.99 for one pound. In bulk, to find the true price, do price divided by quantity. $17.45/5= 3.45. So thats the better deal. Anyways, to find out how much cheaper it is, subtract 3.45 from 3.99. The answer is .54, however, since you need to round to the nearest tenth place, the answer would be .50
