Complete parts a through f below to find nonnegative numbers x and y that satisfy the given requirements. Give the optimum value
MArishka [77]

Answer:

  • y = 81-x
  • the domain of P(x) is [0, 81]
  • P is maximized at (x, y) = (54, 27)

Step-by-step explanation:

<u>Given</u>

  • x plus y equals 81
  • x and y are non-negative

<u>Find</u>

  • P equals x squared y is maximized

<u>Solution</u>

a. Solve x plus y equals 81 for y.

  y equals 81 minus x

__

b. Substitute the result from part a into the equation P equals x squared y for the variable that is to be maximized.

  P equals x squared left parenthesis 81 minus x right parenthesis

__

c. Find the domain of the function P found in part b.

  left bracket 0 comma 81 right bracket

__

d. Find dP/dx. Solve the equation dP/dx = 0.

  P = 81x² -x³

  dP/dx = 162x -3x² = 3x(54 -x) = 0

The zero product rule tells us the solutions to this equation are x=0 and x=54, the values of x that make the factors be zero. x=0 is an extraneous solution for this problem so ...

  P is maximized at (x, y) = (54, 27).

A jet flies at a rate of 1.3 x 10^ 6 feet per hour. Written in scientific notation, which is the best estimate of how many feet
nadezda [96]
(1.3X10^6ft/hr)(2.8X10^3hr)

(1.3*2.8)(10^6*10^3)

Rule (a^b)(a^c)=a^(b+c)

(3.64)(10^(6+3))

3.64(10^9)

3.64X10^9 ft

Technically we only had two significant figures and the answer should be:

3.6X10^9  if we were to express our answer to the correct number of significant figures....

Plzzzzzzzzzzzzzzzzzzzzz help show your work <br><br><br> - 9/2+-8/13
S_A_V [24]

Answer:

-133/26

Step-by-step explanation:

-9/2 + -8/13

First find a common domintor.

26 will be a common domintor.

2 × 13=26 so multiply -9 by 13= -117

13×2=26 so multiply -8 by 2= -16

-117/26 + -16/26 = -133/26
