HI CAN I PLEASE GET SOME HELP PLEASE THANK YOU WICH OF THE FOLLOWING IS EQUIVALENT TO THE EXPRESSION BELOW? Square root of -169 A)13i B)-13 C)13 D)-13i

The equations are- 1) y=-6x+2,  2) y = x^2+7, 3) y = -1/5x^3+7

Step-Wise explanation-

Linear function

let y = -6x+2

if we put x=5 then- y = 32

quadratic function

let y = x^2+7

if we put x=5 then we get y = 32

Cubic function

let y = -1/5x^3+7

if we again put x=5 then we get y= 32

Hence the required functions are y = -6x+2, y = x^2+7, y = -1/5x^3+7

What are functions?

the function is the relationship between units of values. e g y=f(x), for each value of x there is its exists in a set of y. x is an impartial variable even as Y depends variable.

Answer:

Quadratic: y=x^2-27x-160

not too sure of the other ones sorry

Step-by-step explanation:

The correct answer is option B.

What is mean by Triangle?

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

A dilation with a scale factor less than 1 and then a reflection

To this point, we've encountered four kinds of symmetry:

Reflection, rotation, translation, and glide-reflection.

These symmetries are rigid motions as a result of they move a figure whereas conserving its size and shape.

All transformations are isometric. Dilation may be a non-isometric transformation. A stretch isn't a similarity transformation.

Dilations, rotations, reflections, and translations are all similar transformations. Since rotation, reflection, and translation are rigid motions, they preserve each size and shape, whereas dilation solely ensures that the form is preserved.

the multiplier is outlined as the magnitude relation of the dimensions of the new image to the size of the previous image.

the middle of dilation may be a mounted purpose within the plane.

supported the dimensions issue and therefore the centre of dilation, the dilation transformation is defined.

The complete question is :

Which composition of similarity transformations maps polygon ABCD to polygon A'B'C'D'?

a dilation with a scale factor less than 1 and then a reflection

a dilation with a scale factor less than 1 and then a translation

a dilation with a scale factor greater than 1 and then a reflection

a dilation with a scale factor greater than 1 and then a translation

Answer:

Hey there!

Unless the smaller object was rotated 360° (in which case the rotation wouldn't have to be mentioned), you can see that all of the lines are still in the same place and that it wasn't rotated at all. This eliminated any answer option that mentions a rotation, which is A and C. 

Also, if you count the units of one of the straight lines – for example, line AB and A'B' – you can see that the smaller object is four times smaller than the larger object. In the case of line AB and A'B', line AB is 8 units long and A'B' is 2 units long. This means that the scale factor is . 

Lastly, the smaller object was moved from its initial location, which would be in the center of the larger object if it wasn't moved after being scaled down. 

The answer will be B, "a dilation with a scale factor of  and then a translation."
