Answer:

f(x)=-x2

Step-by-step explanation:

I believe the first one has a vertex at (-4, 0), the second at (4, 0), the third at (4, -4). The only remaining answer is the last one.

Solve the following maximization problem graphically.
rjkz [21]

The maximized value of the function is (c) 119/2

<h3>Maximization problem</h3>

Maximization problems are used to determine the optimal solution of a linear programming model

<h3>Objective function</h3>

The objective function is given as:

P(x,y) = 11x + 10y

<h3>Constraints</h3>

The constraints are given as:

22x + 2y \le 68

8x + 16y \le 68

x,y\ge 0

<h3>Graph</h3>

See attachment for the graph of the constraints

From the graph, the optimal solution is: (2.83, 2.83)

So, the maximized value is:

P(x,y) = 11x + 10y

P =11 \times 2.833 + 10 \times 2.833

P =59.493

Approximate

P =59.5

Rewrite as a fraction

P =\frac{119}{2}

Hence, the maximized value of the function is (c) 119/2

Answer:

<h3>23</h3>

<u>Data is:</u>

  • 5, 6, 7

<u>Mean:</u>

  • (5 + 6 + 7)/3 = 6

<u>Standard deviation:</u>

  • σ = \sqrt{((5 - 6)^2+(6-6)^2+(7-6)^2)/3} = \sqrt{2/3}

Correct choice is d

<h3>24</h3>

<u>Data is:</u>

  • -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5

<u>Mean:</u>

  • (-5 -4 - 3 - 2 - 1 + 0 + 1 + 2 + 3 + 4 + 5)/11 = 0

<u>Standard deviation:</u>

  • σ = \sqrt{((-5)^2+(-4)^2+(-3)^2+(-2)^2+(-1)^2+0^2+1^2+2^2+3^2+4^2+5^2)/11} =  \sqrt{10}

Correct choice is d

<h3>25</h3>

<u>Data is:</u>

  • 3, 4, 5, 6, 7

<u>Mean is:</u>

  • 5

<u>Standard deviation:</u>

  • σ = \sqrt{((3-5)^2+(4-5)^2+(5-5)^2+(6-5)^2+(7-5)^2)/5} =  \sqrt{2} ≈ 1.4

Correct choice is d

Don’t know how to solve, help ?
yawa3891 [41]
I believe the answer is 88 because the 120 will create a straight angle which is 180. Then you do 180-120=60. This is the measure I the left angle. Now your answer will be 88
