Simplify the given polynomial expressions as much as possible
bazaltina [42]

Answer:

34a^2 + 21a - 20

Step-by-step explanation:

(12a^2 + 6a -8) - (-22a + 12 - 15a)

12a^2 + 6a - 8 + 22a + 12 - 15a

34^2 + 6a - 8 - 12 + 15a

34^2 + 21a - 20

The graph shows the function f(x).
Lerok [7]

The equation that represents the given data is  \RM \\f(x) = -\sqrt[3]{-x} , Option D is the correct answer.

<h3>What is a Function ?</h3>

It is a statement where two variables , one dependent and one independent are related.

It is given that

a cube root function goes through (8, 2), has an inflection point at (0, negative 1), and goes through (8, negative 3).

The equation given in the options are

\rm f(x) = -\sqrt[3]{x} \\f(x) = -\sqrt[3]{x-1} \\f(x ) =-\sqrt[3]{-x} -1 \\f(x) = -\sqrt[3]{-x}

The function goes through (8,2)

Substituting the values

f(x) = -2

f(x) = \sqrt[3]{7}

f(x) = -3

f(x) = 2

The equation that represents the given data is

\RM \\f(x) = -\sqrt[3]{-x} , Option D is the correct answer.

Help, please in this problem
Nikolay [14]

Answer:

x=9.768

y=6.972

Step-by-step explanation:

For this problem we have to use the trig relationships of cos and sin to figure out the lengths. Cos is equal to adjacent/hypotenuse so we can set it as x/r=.814 and since r is equal to 12 we can do 12 times .814 to get x.

We do a similar process for sin but sin is equal to opposite/hypotenuse so we can set up the equation y/r=.581 and we simply multiply both sides by 12 to get 12*.581 to get y.

Also for future reference adjacent and hypotenuse are based on the angle at use, since ∅ is on the bottom left x is the adjacent side and y is the opposite side.

Given f(x) = x^2 – 3x – 2, what is f(5)?
miskamm [114]

Answer:

f(5)=8

Step-by-step explanation:

Given function: f(x)=x^2-3x-2

To find f(5), simply input x=5 into the function:

\begin{aligned}\implies f(5) & =5^2-3(5)-2\\& = 25-15-2\\& = 10-2\\& = 8\end{aligned}
