Answer:
<em>The dilation is a reduction</em>
Step-by-step explanation:
<u>Dilations</u>
A dilation is a transformation that produces an image that has the same shape as the original but has a different size.
A dilation is described by the scale factor or constant of dilation and the center of the dilation.
Most dilations occur across the origin as its center. If the scale factor is greater than one, then the dilation is an enlargement. If the scale factor is less than one, the dilation is a reduction.
Let's focus on the black shape and the purple shape. The question states the purple shape is a dilation of the black shape. Note all the points (and therefore the side lengths) of the purple shape are equivalent to those of the black shape divided by 3.
This gives a scale factor of 1/3. Since it's less than one, the dilation is a reduction
Answer:
10
Step-by-step explanation:
i think its 10 maybe cuz if u see
the perimeter of a rectangular room is 52 feet. right?
then then height is 2 more than the width. what is the width of the room? so am I right copying the question? yes the question is right copied ok!
now see when u subtract 2 from 12 it gives u 10 and length i as 2 more than the width so maybe 10
Answer:
a. closed under addition and multiplication
b. not closed under addition but closed under multiplication.
c. not closed under addition and multiplication
d. closed under addition and multiplication
e. not closed under addition but closed under multiplication
Step-by-step explanation:
a.
Let A be a set of all integers divisible by 5.
Let ∈A such that
Find
So, is divisible by 5.
So,
is divisible by 5.
Therefore, A is closed under addition and multiplication.
b.
Let A = { 2n +1 | n ∈ Z}
Let ∈A such that where m, n ∈ Z.
Find
So,
∉ A
So,
∈ A
Therefore, A is not closed under addition but A is closed under multiplication.
c.
Let but ∉A
Also,
∉A
Therefore, A is not closed under addition and multiplication.
d.
Let A = { 17n: n∈Z}
Let ∈ A such that
Find x + y and xy
So,
∈ A
Therefore, A is closed under addition and multiplication.
e.
Let A be the set of nonzero real numbers.
Let ∈ A such that
Find x + y
So,
∈ A
Also, if x and y are two nonzero real numbers then xy is also a non-zero real number.
Therefore, A is not closed under addition but A is closed under multiplication.
