Which regular polygon, when rotated 180 degrees about its center, may not be carried onto itself ?

1 answer:

5 0

The polygon that when rotated at 180 degrees about it's center may not be carried onto itself is a quadrilateral. The reason being quadrilateral is not regular in the sense that different sides have different measures.

If y = 7x − 5, which of the following sets represents possible inputs and outputs of the function, represented as ordered pairs?

BaLLatris [955]

Answer:

Correct option is C). {(0, −5), (2, 9), (−3, −26)}

Step-by-step explanation:

Given function is f(x)=7x-5.

Here, Options are given ordered pair

Let, x=0

f(x)=7x-5

f(0)=7(0)-5

f(0)=(-5)

The ordered pair is (0,-5)

Let, x=2

f(x)=7x-5

f(2)=7(2)-5

f(2)=9

The ordered pair is (2,9)

Let, x=(-3)

f(x)=7x-5

f(-3)=7(-3)-5

f(-3)=(-26)

The ordered pair is (-3,-26)

Thus, Correct option is C). {(0, −5), (2, 9), (−3, −26)}

-5x^2-6=-4x using the Quadratic Formula.

a_sh-v [17]

Answer:

Step-by-step explanation:

-5x² - 6 = -4x

-5x² + 4x - 6 = 0

a = -5 ; b = 4 ; c = -6

Discriminant = b² - 4ac

= 4² - 4*(-5)*(-6)

= 16 - 120

= -104

roots = $\dfrac{-b+\sqrt{D}}{2a} \ ; \ \dfrac{-b-\sqrt{D}}{2a}$

$=\dfrac{-4+\sqrt{-104}}{2*(-5)};\dfrac{-4-\sqrt{-104}}{2*(-5)}\\\\=\dfrac{-4+2i\sqrt{26}}{-10} ; \dfrac{-4-2i\sqrt{26}}{-10}\\\\=\dfrac{(-2)[2-i\sqrt{26}]}{-10} \ ; \ \dfrac{(-2)[2+i\sqrt{26}]}{-10}\\\\=\dfrac{2-i\sqrt{26}}{5} \ ; \ \dfrac{2+i\sqrt{26}}{5}$
