Which transformation will always map a parallelogram onto itself?
OA
a 90° rotation about its center
B.
a reflection across one of its diagonals
Ос.
a 180° rotation about its center
OD.
a reflection across a line jolning the midpoints of opposite sides

Answers

Answer 1
Answer:  C) a 180 degree rotation about its center

Explanation:

Draw out a rectangle and make sure it's not a square. So you could have it be longer than it is tall. Imagine rotating that rectangle 180 degrees. The before and after (preimage and image) will be identical. The same applies if we slanted the sides of this rectangle. This shows that any parallelogram has rotational symmetry.

Side note: any rectangle is a parallelogram, but not the other way around.

Answer:

C)  x = 3

Step-by-step explanation:

factor out a 2 to get:

2(x² - 6x + 9) = 0

(x-3)² = 0

x = 3

Answer and Step-by-step explanation:

First, to find the zeros of the function, we can take out a common factor from the equation, and then factor.

The equation has a common factor of 2 (so distribute of the 2 from all of the numbers).

2([tex]x^2 - 6x + 9[/tex])

Now, we factor. Find two numbers that multiplies to [tex]9x^2[/tex] and adds up to -6x.

-3x and -3x.

Now, we substitute these two for -6x.

[tex]2(x^2 - 3x-3x+9)[/tex]

Factor.

[tex]2(x - 3)(x-3)[/tex]

Finally, we set all of the values to 0 and solve for x.

2 ≠ 0

x - 3 = 0    x = 3

x - 3 = 0    x = 3

That means the answer is C. x = 3

(Not shown, but the multiplicity of this x value is 2, because there are two

x = 3)

A) 8

B) 10

C) 17

D) 48

Answers

The answer is d 48 I just took the test

The interquartile range(IQR) of the recorded weight of ken is calculated as 17 pounds.

What is the interquartile range of a data?

The interquartile range(IQR) = third quartile(Q3) - first quartile(Q1)

The third quartile of in the box plot given is : 56 pounds

The third quartile of the data as represented in the box plot given :

39 pounds

The interquartile range(IQR) of ken's data = 56 - 39

= 17 pounds

Hence, The interquartile range(IQR) of the recorded weight of ken is calculated as 17 pounds.

A yield sign is an equilateral triangle with a side length of 36 inches. What is the height (h) of the sign? Leave your answer in simplest radical form.

Answers

Answer:

18[tex]\sqrt{3}[/tex] inches

Step-by-step explanation:

Applying,

Pythagoras theorem,

a²= b²+c²

Where a = hypotenus, b = base of the triangle, c = height.

make c the subject of the equation

c = √(a²-b²)................. Equation 2

From the diagram attached,

Given: a = 36 in, b = (36/2) in = 18 in

Substitute these values into equation 2

c = √(36²-18²)

c = √(1296-324)

c = √(972)

c = √(972)

c = √(324×3)

c = 18[tex]\sqrt{3}[/tex] inches
