Which transformation was performed on PQRS to form P'QʻR'S'? (1 point)
REY [17]

Given:

A transformation was performed on PQRS to form P'QʻR'S'.

To find:

The transformation.

Solution:

The given graph shows two similar polygons. It means, dilation was performed.

From the given graph it is clear that,

PS=2 units

P'S'=1 units

Now,

\text{Scale factor}=\dfrac{P'S'}{PS}

\text{Scale factor}=\dfrac{1}{2}

A dilation factor of \dfrac{1}{2} was performed on PQRS to form P'QʻR'S'.

Therefore, the correct option is (3).

zavuch27 [327]

Answer:

Therefore the area of the screen cleared is 1414.28 cm².

Step-by-step explanation:

Given:

a windscreen wiper of a vehicle of length 30 cm

Consider this length as Radius of Semicircle, r = 30 cm

clears out an angle of 180 degrees implies Semicircle Shape

pie=22/7

To Find:

Area of the screen cleared ​

= ?

Solution:

We have

\textrm{Area of Semicircle}=\frac{1}{2}\pi(radius)^{2}

Substituting r and pie we get

\textrm{Area of Semicircle}=\frac{1}{2}\times \frac{22}{7}(30)^{2}=1414.28\ cm^{2}

Therefore the area of the screen cleared is 1414.28 cm².
