Answer: i dont really know if im right but here! :L

Step-by-step explanation: Now, say G is an Abelian group, finitely generated from generator In this sense abelian groups are “more interesting” than vector spaces. and in the table below, the second last column is the identity, while the last column is cyclic of order 4, with 9g the generator

Answer:

it is A

Step-by-step explanation:the red color is to subtract or negative value and the blue one is for addition or positive value

-x^2-2x+4 the first row

-(x^2+2x+1) for the second row or (-x^2-2x-1) is the same

put it together

-2x^2-4x+3

How do you write a ratio as a fraction in lowest terms

sp2606 [1]

I found this online hope it helps

1 foot is 12 inches, so 2 feet are 24 inches.

The ratio is therefore 24/52. However, you're asked to have the lowest terms fraction, so let's look at common factors:

24 = 2*2*2*3

52 = 2*2*13.

The two numbers share a common factor of 4, so divide by 4 on both sides of the equation for success:

24/52 = 6/13.

Step-by-step explanation:

y=2x+1

(-0.8; -0.6)

(x, y)

-0.6=2×(-0.8)+1

-0.6=-0.6

it's true

y=-3x-3

-0.6=-3×(-0.8)-3

-0.6=-5.4

it's not true

Peter's farm has 160 meters of fencing, and he wants to fence a rectangular field thatborders a straight river. He needs no fenc

Likurg_2 [28]

ANSWER

3200 m²

EXPLANATION

Peter wants to build a fence around a rectangular field, except for one side because the river is there,

So, the total perimeter of the fence is,

$P=W+W+L=2W+L$

And this is equal to 160 m. Solving for L,

$160=2W+L\text{ }\Rightarrow\text{ }L=160-2W$

The area of this field is,

$A=WL$

Replace L with the expression we found from the perimeter,

$A=W(160-2W)=160W-2W^2$

The area is given by a quadratic function whose leading coefficient is negative, which means that the graph is a downward parabola and, therefore, the vertex is the maximum value of the area.

The x-coordinate of the vertex is given by,
