HELP!!! I'm struggling in this class could you please help a person out?

Answer:

Options (2) and (3)

Step-by-step explanation:

Rigid transformation like translation, rotation or reflection form the image with no change in the area or shape.

By applying dilation, area of the image shape gets dilated by the scale factor 'k'.

If k > 1, area of the image will be greater than the original shape.

If 0 < k < 1, are of the image will be smaller than the original.

Option (1),

There is a dilation by a scale factor of $\frac{2}{3}$ and $0$ ,

Therefore, image will be smaller than the original.

Option (2)

There are two dilations.

First dilation is by a scale factor of 2 and the second is by a scale factor of $\frac{2}{3}$ .

By first dilation area of the image will get doubled.

Followed by the dilation by a scale factor of $\frac{2}{3}$ , area of the image will be dilated by the scale factor = $2\times \frac{2}{3}$

= $\frac{4}{3}$

Since, $\frac{4}{3}>1$ , image will be greater than the original.

Option (3)

In this option polygon is dilated by a scale factor $\frac{3}{2}$ .

Since, $\frac{3}{2}>1$

Image will have the greater area than the original.

Option (4)

In this option polygon is dilated by a scale factor $\frac{1}{2}$ .

Therefore, area of the image will be less than the area of the original.

Options (2) and (3) will be the correct options.

Decide weather a triangle could have the given angles measures explain your responds 140,70,186

Zolol [24]

You can’t have a triangle with the given angles cause 140+70+186=396 while 180 must be the amount measure of all 3 angles

Five years ago, Tom was one third as old as his father was then.In 5 years, Tom will be half as old as his father will be then.

Answer:

The father is 35years old and the son Tom is 15years old

Step-by-step explanation:

Let the father's be y

Let Tom's age be T

5 years ago:

The father's age is: y — 5

Tom's age:

T— 5.

But Tom's age was one third the father's age. This is written as:

T — 5 = 1/3(y — 5)

3(T — 5) = y — 5

3T — 15 = y — 5

3T — y = — 5 + 15

3T — y = 10 (1)

In 5years time:

The father's age is:

y + 5

Tom's age:

T + 5

But in 5years time, Tom will be half as old as his father. This is written as:

T + 5 = 1/2(y + 5)

2(T + 5) = y + 5

2T + 10 = y + 5

2T — y = 5 — 10

2T — y = — 5 (2)

Therefore, the equations are

3T — y = 10 (1)

2T — y = — 5. (2)

Solving by elimination method:

Subtract equation (2) from (1)

3T — y = 10

— (2T — y = — 5)

T = 15

Substituting the value of T into equation (1)

3T — y = 10

3(15) — y = 10

45 — y = 10

45 — 10 = y

y = 35

Therefore,

The father is 35years old and the son Tom is 15years old
