Which matrix is equal to T + V

Mathematics
1 answer:
UkoKoshka [18]3 years ago
6 0

Answer:

A

Step-by-step explanation:

T11 + V11 = 0.1 + 3.2 = 3.3; T12 + V12 = -10.5

This line all by itself limits you to a and b. That's because both answers A and B begin with t11 + v11= 3.3. You just add them as you see them.  t12 + v12 = - 1.9 - 8.6 = -10.5

I'll finish off the addition, but you can see that A is right already.

t21 + v21 = 2.5 + 2.8 = 5.3;  t22 + v22 = 8.2 - 1.4 = 6.8

t31 + v31 = -7.8 - 2.3 = -10.1; t32 + v32 = 1.4 + 5.1 = 6.5

That's how these matrices  are added together.

A rectangular garden has a walk around it of width x. The garden is 20 ft by 15 ft. Write a function representing the combined w
kodGreya [7K]

Answer: A(x) = 15 ft + 2x

 

EXPLANATION

 

Given,

The dimension of the rectangular garden is 20 ft by 15 ft.

Dimension of a rectangle is written as Length by Width

This implies that,

Length of the garden = 20 ft

Width of the garden = 15 ft

 

The garden has a walk around it of width x.

The combined width of the garden = Width of garden + 2x

[we are adding twice the width of the walk because it is around the garden (this means it will add to the width of the garden on both the left and right sides)]

 

Combined width of the garden, A(x) = Width of garden + 2x

Since width of the garden = 15 ft

A(x) = 15 ft + 2x

What binomial do you have to add to the polynomial:
marshall27 [118]

Answer:

a)  -2x^2+5xy

b)  -3y^2+5xy

Step-by-step explanation:

<u>Part (a)</u>

Given polynomial  :2x^2+3y^2-5xy+1

The binomial that should be added to the given polynomial to get a polynomial that does not contain the variable x is:

-2x^2+5xy

(2x^2+3y^2-5xy+1)+(-2x^2+5xy)

=2x^2+3y^2-5xy+1-2x^2+5xy

=2x^2-2x^2+3y^2-5xy+5xy+1

=3y^2+1

<u>Part (b)</u>

Given polynomial  :2x^2+3y^2-5xy+1

The binomial that should be added to the given polynomial to get a polynomial that does not contain the variable y is:

-3y^2+5xy

(2x^2+3y^2-5xy+1)+(-3y^2+5xy)

=2x^2+3y^2-5xy+1-3y^2+5xy

=2x^2+3y^2-3y^2-5xy+5xy+1

=2x^2+1
