The first few steps in deriving the quadratic formula are shown.
Kisachek [45]

In the first few steps for deriving the quadratic formula left side of the equation due to the distributive property for balancing the equation.

<h3>What is quadratic equation?</h3>

A quadratic equation is the equation in which the highest power of the variable is two.

Here, The first few steps in deriving the quadratic formula are shown in the table.

Use the substitution property of equality to solve it further,

-c=-ax² +bx

Now factor out the term a, to solve further as,

    - c = a (x² + b/a x)

for half of the b value and square it to determine the constant of the perfect square trinomial as,

     (b/2a)² = b²/4a²

Now  the distributive property needs to be applied to determine the value to add to the left side of the equation to balance the sides of the equation.

  -c + b²/4a² = a(x² + b/a x + b²/4a² )

Thus, the distributive property needs to be applied to determine the value to add to the left side of the equation to balance the sides of the equation.

The volume of the cone shown is 5 cubic inches. What is the height of a cone with the same base diameter but a volume of 10 cubi
MaRussiya [10]

Answer:

The height of the second cone is 2 <em>h</em>₁.

Step-by-step explanation:

The volume of a cone is:

V=\pi\ r^{2}\frac{h}{3}

The volume of the first cone is, <em>V</em>₁ = 5 in³.

The volume of the second cone is, <em>V</em>₂ = 10 in³.

The two cones have the same base diameters.

This implies that the two radii are same, i.e. <em>r</em>₁ = <em>r</em>₂.

Compute the height of the second cone as follows:

   r_{1}=r_{2}

\frac{3\cdot V_{1}}{\pi\ h_{1}}=\frac{3\cdot V_{2}}{\pi\ h_{2}}

  \frac{V_{1}}{h_{1}}=\frac{V_{2}}{ h_{2}}

  \frac{5}{h_{1}}=\frac{10}{h_{2}}

  h_{2}=2\ h_{1}

Thus, the height of the second cone is 2 <em>h</em>₁.

Consider the function represented by 9x+3y = 12 with x as the independent variable. How can this function be
Delicious77 [7]

Answer:

  • f(x) = -3x + 4

Step-by-step explanation:

<u>Given function:</u>

  • 9x + 3y = 12

<u>Putting this into slope-intercept form: y = mx + b</u>

  • 9x + 3y = 12
  • 3y = -9x + 12
  • y = -3x + 4

<u>Replacing y with f(x)</u>

  • f(x) = -3x + 4
