Please choose the option that would best fit the empty space above: Group of answer choices only one optimal solution multiple o
Scrat [10]

Answer:

Follows are the solution to this question:

Step-by-step explanation:

In this question, some of the data is missing, that's why this question  can be defined as follows:

It Includes an objective feature coefficient, its sensitivity ratio is the ratio for values on which the current ideal approach will remain optimal.

When there is Just one perfect solution(optimal solution) then the equation is:

Max \ Z = \$ 5x_1 + \$10x_2\\\\Subject\  to: \\\\8x_1 + 5x_2 \leq  80\\\\2x_1 + 1x_2 \leq 100\\\\x1, x2 \geq 0

When there are Several perfect solutions then the equation is:

Max \ Z = \$ \ 200x_1 + \$ \ 100x_2\\\\ Subject \ to:\\\\8x_1 + 5x_2 \leq 80\\\\2x_1 + 1x_2 \leq 100\\\\x1, x2 \geq 0

When there is also no solution, since it is unlikely then the equation is:

Max \ Z = \$40x_1 + \$10x_2 \\\\Subject \ to:\\\\8x_1 + 5x_2 \leq 80\\\\2x_1 + 1x_2 \geq 100\\\\x_1, x_2 \geq 0

When there is no best solution since it is unbounded then the equation is:

Max \ Z = \$ 30x_1 + \$15x_2 \\\\Subject to:\\\\8x_1 + 5x_2 \geq 80\\\\2x_1 + 1x_2 \geq 100\\\\x_1, x_2 \geq 0\\

Rewrite the function f(x)=4(x-2)²-8 in the form f(x)=ax²+bx+c.
tino4ka555 [31]

Answer:

4x^{2}-16x+8

Step-by-step explanation:

4(x - 2)(x - 2) - 8 = 4(x^{2} - 4x + 4) - 8 = 4x^{2} - 16x + 16 - 8 = 4x^{2} - 16x + 8.

What number would complete the pattern 16,4,12,36,9,27,44,11
lara31 [8.8K]
<span>This isn't very difficult to figure out, you just need to look at these numbers in pairs. So, 16 minus 4 is 12. Then the next pair of numbers, 36 minus 9 is 27. And to complete the pattern, you just have to look at the final pair: 44 minus 11 is 33. So the number that would complete the pattern is 33.Hope this helps. Let me know if you need additional help!</span>
