A dilation with center (0,0) and scale factor "k" is applied to a polygon. What dilation can you apply to the image to return it

to the original preimage?

So when we scale up this image, all points' distances from the center are multiplied by k. We want to then put them back to where they were before.

Thinking about inverse operations, we could just divide by k[tex], right? But the problem with having a scale factor is we can only multiply.\\Think about fractions. Dividing by a fraction is the same as multiplying by the reciprocal, right? \\So if we think of [tex]k as \frac{k}1, then the opposite reciprocal would be \boxed{\frac{1}k}

1. Which of the following shows the correct use of the Distributive Property when solving 1/3( 33
vagabundo [1.1K]

Answer:

The option (\frac{1}{3}\times 33)-\frac{1}{3}y=\frac{1}{3}135.2 is correct

Step-by-step explanation:

Given equation is \frac{1}{3}(33-y)=135.2

The option shows correct usage of distributive property is

(\frac{1}{3}\times 33)-\frac{1}{3}y=\frac{1}{3}135.2

( by distributive property a(x+y)=ax+ay here a=\frac{1}{3}, x=33 and y=-y )

Therefore the option (\frac{1}{3}\times 33)-\frac{1}{3}y=\frac{1}{3}135.2 is correct.

All sides of quadrilateral ABCD ABCD A, B, C, D are tangent to circle PPP. What is the perimeter of the quadrilateral below?
noname [10]

Answer:

The answer is below

Step-by-step explanation:

A tangent is a line which touches a circle at one point. The angle between a tangent and a circle is 90°.

The two tangent theorem states that tangent that meet at the same point are equal in length.

Therefore:

CD = c + d

but c = 5.1, hence:

CD = 5.1 + d

12.1 = 5.1 + d

d = 7

AD = a + d; but AD = 12.2, d = 7

12.2 = a + 7

a = 5.2

AB = a + b; but b = 3.3

AB = 5.2 + 3.3 = 8.5

BC = b + c = 3.3 + 5.1 = 8.4

Perimeter of ABCD = AB + BC + CD + AD = 8.5 + 8.4 + 12.1 + 12.2 = 41.2
