Answer:

which class of question is this

Answer:

x^3-3x^2+2x-6

Step-by-step explanation:

ƒ(x) = x^2 + 2

g(x) = x – 3

(ƒ • g)(x) = ( x^2 + 2) * (x – 3)

FOIL

               = x^3 -3x^2 +2x -6

Answer:

27

Step-by-step explanation:

r=rate of 1 worker

t=time

3 x r x 45 = 5 x r x t

t= 3 x 45 / 5

t= 3 x 9

t= 27

Answer:

56 m²

Step-by-step explanation:

Hi there!

[tex]A=\displaystyle\frac{1}{2} bh[/tex] where b is the base and h is the height of the triangle

Plug in the base (14 m) and the height (8 m):

[tex]A=\displaystyle\frac{1}{2} (14)(8)\\\\A=\displaystyle\frac{1}{2} (112)\\\\A=56[/tex]

Therefore, the area of the triangle is 56 m².

I hope this helps!

Answer:

X= 150º

Y= 60º

(I strongly recommend reading the explanation so you can understand it because its way easier than you think!!)

Step-by-step explanation:

2x+90=5x

-2x        -2x

90=3x

x=30

2(30)+90= 150º

5(30)=150º

Angle x= 150º

Both angles are congruent because they are vertical angles!!

Now we gotta figure out y so you see that there are two lines crossing. (Both sides will work for this) Both angles are supplementary angles which means they combine to make a 180º angle. So if we already know both sides of x are 150º then we can infer that 150+y=180. All you have to do now is subtract 150 from 180 and you will get y.

180º-150º= 30º

Angle y= 30º

But that is not all do not forget that is says (3y)º which means we gotta multiply y by 3.

Sooo 30 x 3 is 60º

Therefore that angle is 60º

Subtract  0.75 p  from  p  to get 0.25 p

Answer: A D. x - 11

b -3x + 9

c -30x^2 + 28x - 6;

Step-by-step explanation:

The functions that have end behavior lim x -> ∞ f(x) = -∞ is

y= x, y= x³ and y= 1/ (1+ [tex]e^{-x[/tex]).

Here the function obey the rule as

lim x -> ∞ f(x) = -∞

So, the function

f(x) = y

lim x -> ∞ y = -∞

First, y= x

x = - ∞

y =  = - ∞ which is True

Second, y= x³

x - > -∞

y= (-∞)³ = -∞

y = -∞ which is True

Third, y= 1/ (1+ [tex]e^{-x[/tex])

x - > -∞

y = -∞ which is True

Answer:

I bet you're talking about column vectors,

[tex]\begin{bmatrix}-5\\4\\5\end{bmatrix}, \begin{bmatrix}2\\-1\\5\end{bmatrix},\text{ and }\begin{bmatrix}-17\\16\\45\end{bmatrix}[/tex]

If these vectors are linearly independent, this means that

[tex]c_1 \begin{bmatrix}-5\\4\\5\end{bmatrix} + c_2 \begin{bmatrix}2\\-1\\5\end{bmatrix} + c_3 \begin{bmatrix}-17\\16\\45\end{bmatrix} = \begin{bmatrix}0\\0\\0\end{bmatrix}[/tex]

only if [tex]c_1=c_2=c_3=0[/tex].

In matrix form, we can write this as a system of linear equations,

[tex]\begin{bmatrix}-5&2&-17\\4&-1&16\\5&5&45\end{bmatrix}\begin{bmatrix}c_1\\c_2\\c_3\end{bmatrix} = \begin{bmatrix}0\\0\\0\end{bmatrix}[/tex]

This system has a potentially non-zero solution so long as the coefficient matrix is not singular.

Compute the determinant:

[tex]\begin{vmatrix}-5&2&-17\\4&-1&16\\5&5&45\end{vmatrix} = -5 \begin{vmatrix}-1&16\\5&45\end{vmatrix} - 4 \begin{vmatrix}2&-17\\5&45\end{vmatrix} + 5 \begin{vmatrix}2&-17\\-1&16\end{vmatrix} \\\\ \begin{vmatrix}-5&2&-17\\4&-1&16\\5&5&45\end{vmatrix} = -5(-45-80) - 4(90+85) + 5(32-17) \\\\ \begin{vmatrix}-5&2&-17\\4&-1&16\\5&5&45\end{vmatrix} = 0[/tex]

The coefficient matrix is singular, so there is no non-zero solution to the system, and in turn the given vectors are linearly dependent.
