The variation equation is p = kr^2

<h3>How to determine the variation equation?</h3>

The variables are give as:

Pressure = P

Radius= r

The direct variation from p to the square of r is represented as:

$p\ \alpha\ r^2$

Express as an equation

p = kr^2

Where k represents the constant of variation

Hence, the variation equation is p = kr^2

Is the following shape a rectangle?how do you know?

adelina 88 [10]

Answer:

The following shape is not a rectangle, but a square. I know this because the length and width are the same amount of square inch(feet, what ever the square counts for on your graph.) and rectangles width are typically longer than their length. However a square shares the same length and width,

Y-6=4(x+5) what is y and x intercept?

Law Incorporation [45]

Answer:

x = $(-\frac{13}{2} ,0)$ y = (0,26)

Step-by-step explanation:

First find the x intercept

To find the x intercept, substitute 0 for y and solve for x.

$(0)-6=4(x+5)$

Rewrite the equation as $4(x+5)=(0)-6$

$4(x+5)=(0)-6$

Subtract 6 from 0.

$4(x+5)=-6$

Divide each term in $4(x+5)=-6$ by 4.

$\frac{4(x+5)}{4} =\frac{-6}{4}$

Cancel the common factor of 4.

$x+5=\frac{-6}{4}$

Simplify $\frac{-6}{4}$

$x+5=-\frac{3}{2}$

Subtract 5 from both sides of the equation.

$x=-\frac{3}{2} -5$

To write $-5$ as a fraction with a common denominator, multiply by $\frac{2}{2}$

$x=-\frac{3}{2}-5$ · $\frac{2}{2}$

Combine $-5$ and $\frac{2}{2}$ .

$x=-\frac{3}{2} +\frac{-5*2}{2}$

Combine the numerators over the common denominator.

$x=\frac{-3-5*2}{2}$

Simplify the numerator.

$x=\frac{-13}{2}$

Move the negative in front of the fraction.

$x=-\frac{13}{2}$

x = $(-\frac{13}{2} ,0)$

-----------------------------------------------------------------------------------------------------

Find the y-intercepts.

To find the y-intercept(s), substitute in 0 for x and solve for y.

$y-6=4((0)+5)$

Add 0 and 5.

$y-6=4 *5$

Multiply 4 by 5.

$y-6=20$

Add 6 to both sides of the equation.

$y=20+6$

Add 20 and 6.

$y=26$

y = (0, 26)
