The surface area is the area of the rectangle - it has been rolled so no different.

25 x 21 = 525 cm^2

The area of the piece of paper is (25cm x 21cm) =  525 cm² .

There's no reason it should change when you bend the paper
into different shapes.

Question: Consider the similarity transformation of ΔABC to produce ΔEDF.
german

Answer:

see the explanation

Step-by-step explanation:

we have triangle  ΔABC

step 1

Rotate 90 degrees clockwise ΔABC about point C to obtain ΔA'B'C'

Remember that

A rotation is a rigid transformation

An object and its rotation are the same shape and size, but the figures may be turned in different directions

so

ΔABC and ΔA'B'C' are congruent

ΔABC≅ ΔA'B'C

step 2

Dilate the triangle ΔA'B'C' to obtain triangle ΔEDF

Remember that

A dilation is a non rigid transformation

A dilation produces similar figures

If two figures are similar, then the ratio of its corresponding angles is proportional and its corresponding angles are congruent

Find the scale factor of the dilation

The scale factor is equal to the ratio of corresponding sides

In this problem

Let

z ----> the scale factor

so

z=\frac{ED}{AB}=\frac{DF}{BC}=\frac{EF}{AC}

Multiply the length sides of triangle ΔA'B'C' by the scale factor z to obtain the length sides of triangle ΔEDF

Note: in this problem the scale factor z is less than 1

That means ----> the dilation is a reduction

Which is true about the vertex?
vfiekz [6]

Answer:

5. It's halfway between the x-intercepts.

Step-by-step explanation:

The vertex is halfway between the two x-intercepts when parabola is coordinate of the vertex. The points and x and y intercept crosses the x-axis vertically so that a u shaped lines are formed. The quadratic equation is used to find the points on the parabola.
