Rember rows times columns.

=>
a11 = 4*0 + 0*(-3) = 0

a12 = 4*1 + 0*1 = 4 + 0 = 4

a21 = -1*0 + 2*(-3) = 0 - 6 = -6

a22 = -1*1 + 2*1 = -1 + 2 = 1

a31 = -3*0 + (-1)*(-3) = 0 + 3 = 3

a32 = -3*1 + (-1)*1 = -3 - 1 = -4

I need help!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Zina [86]

Answer:

Yes, x and y have a proportional relationship.  

Step-by-step explanation:

A proportional relationship means that, when comparing two quanities, that they are both changing at a constant (same) amount.  When looking at a table to compare quantities, you can see that the pounds of tomatoes 'x' is increasing by one (1) each time.  If you look at the amount spent in dollars 'y', you can see that for each pound (x), the cost is increasing by $4.  So, since for every pound of tomatoes that is purchased increases by $4, then their relationship is proportional.

The volume of a cylinder is 770 cm. It's height is 5 cm. Find its approximate radius.
Alinara [238K]

Hey there,

The equation for the volume of a cylinder is V = πr²h.

The first step into finding the radius is to plug in what you already know into the equation:

  • 770 = πr²5

We divide both sides by 5:

  • 154 = πr²

Now we divide both sides by π:

  • 49.0197224723 = r²

Finally we just do the square root of 49.0197224723:

  • 7.0014086063 = r

The radius therefore would be about 7cm.

Hope I helped,

Amna

What is the standard form of the polynomial 4x+6y^3x-xy+xy^2
meriva

The required standard form is 6y^3x+xy^2-xy+4x

<h3>Polynomial function</h3>

Given the polynomial function expressed as:

  • 4x+6y^3x-xy+xy^2

We are to express this polynomial in standard form

To do that, we will write the degrees of the variables in descending order of magnitude as shown:

4x+6y^3x-xy+xy^2\\6y^3x+xy^2-xy+4x

Hence the required standard form is 6y^3x+xy^2-xy+4x
