To solve this problem yu must apply the proccedure shown below:

 1. You have that the <span>focus of the parabola is located at (0,–2) and the directrix is represented by y=2. Therefore, you have:
</span>
 √(x0-0)²+(y0-(-2))²=|y-2|

 2. By simplifying and clearing x², you obtain:

 (√x0²+(y0+2)²)²=(y0-2)²
 x0²+(y0+2)²=(y0-2)²

 { Note: x0²=x and y0=y)

 x²=-8y

 The answer is: x²=-8y

Write any 4 laws of exponents.<br>​
emmainna [20.7K]

         \rule{50}{1}\large\blue\textsf{\textbf{\underline{Question:-}}}\rule{50}{1}

       <em>Write any 4 laws, or properties, of exponents.</em>

<em />

<em>        </em>\rule{50}{1}\large\blue\textsf{\textbf{\underline{Answer and how to solve:-}}}\rule{50}{1}

\Large\text{Law number 1:-}

\Large\text{$a^n*a^m=a^{n+m}$}

\Large\text{It states that:-}

                        When we multiply together numbers with the same base,

                         we add the exponents.

\Large\text{Law number 2:-}

\Large\text{$a^m:a^n=a^{m-n}$}

\Large\text{It states that:-}

                     When we divide numbers with the same base, we

                     subtract the exponents.

\Large\text{Law number 3:-}

\Large\text{$(\displaystyle\frac{x}{y}) ^n=\frac{x^n}{y^n}$}

\Large\text{It states that:-}

                 If we have a fraction to a power, we raise the numerator and

               the denominator to that power.

And then last but not least,

\Large\textit{Law number 4:-}

\Large\text{$a^{-m} =\displaystyle\frac{1}{a^m}$}

\Large\text{It states that:-}

                   If we have a number with a negative exponent, we flip it over.

Select an equation that passes through the point (5,7) and is perpendicular to the line x=4
alexandr1967 [171]

y = 7

x = 4 is a vertical line parallel to the y- axis passing through all points with an x- coordinate of 4

A line perpendicular to x = 4 will be a horizontal line parallel to the x- axis with equation y = c where c is the value of the y- coordinate the line passes through.

line passes through (5 , 7) with y- coordinate 7

The equation is therefore y = 7

Hi so i need help with 10 and 12 ASAP is due 11:40 I’m giving away all my points thx
blsea [12.9K]

Hi.

First, I am going to give you some definitions.This will help you do the problems.

-Complementary angles have a combined sum of 90.

- Supplementary angles have a combined sum of 180.

10. 40+50=90- so YES.

12. 159+20= 179.-so NO.

Make sure you learn the definitions properly next time!

=)
