Answer:

The box to the left will have the equation p(x) = 5x² and the box to the right will have the equation n(x) = $\frac{1}{5} x^{2}$

Step-by-step explanation:

The coefficient of the x² decides how wide or narrow a quadratic graph is. If the coefficient is a fraction of 1, the smaller the fraction the wider the graph gets. If the coefficient is a number bigger than 1, the bigger the number, the narrower the graph gets.

I hope this helps you

f (x)=x^2-10x+25-29

f (x)=(x-5)^2-29

vertex (-(-5), -29)

vertex (5,-29)

y varies jointly with w and x, inversely with z, and suppose y=360 when w =8,x=15, and z =3. Write the equation that models this

Lunna [17]

<span>Y varies jointly with w and x, inversely with z
this means that
</span>y ∝ wx / z
in equation form
y = kwx / z
where k is the proportionality constant
360 = k ( 8 ) ( 15 ) / 3
k = (360) ( 3) / ( 8 ) ( 15 )
k = 9
so the eqution is
y = 9wx / z

Find the values of x and y. Round your answers to the nearest tenth if necessary,

Eduardwww [97]

Answer:

$x=12,\\y=12\sqrt{3}$

Step-by-step explanation:

In any 30-60-90 triangle, the side lengths are in the ratio $x:x\sqrt{3}:2x$ , where $2x$ is the hypotenuse, or longest side, of the triangle and $x$ is the side opposite to the 30 degree angle.

In the given 30-60-90 triangle, the longest side (hypotenuse) is marked as 24. Since $x$ is opposite to the 30 degree angle,

Therefore, we have:

$x=\frac{24}{2},\\x=\boxed{12}$

Based on our side length ratio $x:x\sqrt{3}:2x$ , $y$ is then:

$y=x\sqrt{3}\text{ for}\implies x=12,\\y=\boxed{12\sqrt{3}}$
