Answer:

D

Step-by-step explanation:

The equation of the parabola is of the form

y = ax² + c ( where c is the y- intercept )

Here c < 0

Since the parabola has a maximum value and opens down then a < 0

Thus the only equation that could represent this parabola is

y = - x² - 3 → D

84 2/3% to a fraction in lowest terms
RoseWind [281]

The evaluation of 84 2/3% to a fraction in its lowest term is \mathbf{ \dfrac{127}{150} }

<h3>What is a fraction?</h3>

Fractions are sections or parts of a whole. They are divided into two parts, the numerator, and the denominator.

From the given information, we are to convert a mixed fraction into its lowest terms. By doing that, we are to convert it to an improper fraction.

\mathbf{= 84 \dfrac{2}{3}\%}

\mathbf{= \dfrac{(84 \times 3)+2}{3} \%}

\mathbf{= \dfrac{254}{3} \%}

\mathbf{= \dfrac{254}{3} \times \dfrac{1}{100}}

\mathbf{= \dfrac{254}{300} }

Divide both the numerator and denominator by (2)

\mathbf{= \dfrac{127}{150} }
