Mathematics

Answer:

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

Step-by-step explanation:

Assuming that the function is

f(x)=(x-1)(x^2+2)

First, we need to remove the parenthesis. Once this is done, we get

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

Now that the parenthesis are gone, we can differentiate each term. To do this, we can use the power rule, which states

f(x)=x^n\\f'(x)=nx^{n-1}\\

This gives us

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

Drina wrote the system of linear equations below.
zalisa [80]

Answer:

Option c, A square matrix

Step-by-step explanation:

Given system of linear equations are

3x-2y=-2\hfill(1)

7x+3y=26\hfill(2)

-x-11y=46\hfill(3)

Now to find the type of matrix can be formed by using this system

of equations

From the given system of linear equations we can form a matrix

Let A be a matrix

A matrix can be written by

A=co-efficient of x of 1st linear equation    co-efficient of y of 1st linear equation   constant of 1st terms linear equation

co-efficient of x of 2st linear equation   co-efficient of y of 2st linear equation  constant of 2st terms linear equation

co-efficient of x of 3st linear equation   co-efficient of y of 3st linear equation    constant of 3st terms linear equation           3\times 3

which is a 3\times 3 matrix.

Therefore A can be written as

A= \left[\begin{array}{lll}3&-2&-2\\7&3&26\\-1&-11&46\end{array}\right] 3\times 3

Matrix "A" is a 3\times3 matrix so that it has 3 rows and 3 columns

A square matrix has equal rows and equal columns

Since matrix "A" has equal rows and columns Therefore it must be a square matrix

Therefore the given system of linear equation forms a square matrix

What is the slope-intercept form for<br> y – 6 = 3 ( x− 1/3 )
Leviafan [203]

Answer:

y=3x+5

Step-by-step explanation:

This is th eanswer because slope intercept form is always y=mx+b.

So, if you simplify the right side of the equation, you then get

y-6=3x-1, I got that because 3 multiplied by -1/3, you get -1.

Then you add 6 to both sides to isolate y by itself. So, now you have

y=3x+5.

Hope this is helpful
