s344n2d4d5 [400]3 years ago
8 0

<u>Answer:</u>

The correct answer option is C. f(x)=-2x^3-2x^2+12x.

<u>Step-by-step explanation:</u>

From the given graph of the polynomial function, we can see that the graph passes through the following points: (-3,0), (0,0) and (2,0).

So the roots or zeros of this polynomial function are: -3,0 and 2.

Now, we'd graph the equation of the given polynomial and will check for roots and end behavior of the graph.

Therefore, the polynomial function that is represented by the graph is:

f(x)=-2x^3-2x^2+12x

Por la seguridad de su personal y sus clientes una agencia bancaria se instalara una camara de video en un soporte de pared de m
yulyashka [42]

Answer:

16.24°

Step-by-step explanation:

Are you trying to find the angle of depression from the camera to the cashier?

Assume that the camera is 2.24 m high and the cashier is 7.69 m away.

1. Angle of elevation from cashier

tanθ = 2.24/7.69 = 0.2913

θ = arctan(0.2913) = 16.24°  

2. Angle of depression from camera

∠ of depression = ∠ of elevation = 16.24°

Solve: 7 x + 2 y = 16; -21 x-6 y = 24 Solve : 7 x + 2 y = 16 ; -21 x - 6 y = 24​
Marat540 [252]

Answer:

No solution

Step-by-step explanation:

<h3>Solving system of linear equations:</h3>

 7x + 2y = 16 ----------------(I)

-21x - 6y = 24 -----------------(II)

\sf \dfrac{a_1}{a_2}=\dfrac{7}{-21}=\dfrac{-1}{3}\\

\sf \dfrac{b_1}{b_2}=\dfrac{2}{-6}=\dfrac{-1}{3}

\sf \dfrac{c_1}{c_2} =\dfrac{16}{24}=\dfrac{2}{3}\\\\ \dfrac{a_1}{a_2}=\dfrac{b_1}{b_2} \neq  \dfrac{c_1}{c_2}

So, the lines are parallel and has no solution

Solve 5c − c + 10 = 34.
makkiz [27]

Answer: 6

Step-by-step explanation: 1. 5c-c= 4c. The equation would then be 4c+10=34.

2. From there, you subtract 10 from both sides of the equation. By doing this, you have the variable and the nonvariable on separate sides of the equation.

3. After doing that, you should have 4c=24. To get the variable by itself, divide both sides by 4. 4c/4 is c and 24/4 is 6.

The final answer is 6. Hope this helped you:)
