What are the solutions for x when y is equal to 0 in the following quadratic

Mathematics
1 answer:
navik [9.2K]3 years ago
6 0

<u>Answer:</u>

The correct answer option is E) No solution.

<u>Step-by-step explanation:</u>

We are given the following quadratic equation which we are to solve for x when the value of y is 0:

y = x ^2+ 6x +12

x ^2+ 6x +12=0

Using the quadratic formula since there are no factors:

x=\frac{-b \pm \sqrt{b^2-4ac }}{2a}

Substituting the values in the formula to get:

x=\frac{-6 \pm \sqrt{6^2-4(1)(12) }}{2(1)}

x=-3+\sqrt{3}i or x=-3-\sqrt{3}i

There are no real number solutions to this quadratic equation.

1) f(x) = 2x + 4, g(x) = 4x2 + 1; Find (g ∘ f)(0).
Sholpan [36]

Answer:

<h2>(g \: \circ \: f)(0) = 17</h2>

Step-by-step explanation:

f(x) = 2x + 4

g(x) = 4x² + 1

In order to find (g ∘ f)(0) we must first find

(g ° f )(x)

To find (g ° f )(x) substitute f(x) into g(x) that's for every x in g(x) replace it with f(x)

That's

<h3>(g \: \circ \: f)(x) = 4( ({2x + 4})^{2} ) + 1 \\  = 4(4 {x}^{2}  + 16x + 16) + 1 \\  =  {16x}^{2}  + 64x + 16 + 1</h3>

We have

<h3>(g \: \circ \: f)(x) =  {16x}^{2}  + 64x + 17 \\</h3>

Now to find (g ∘ f)(0) substitute the value of x that's 0 into (g ∘ f)(0)

We have

<h3>(g \: \circ \: f)(0) = 16( {0})^{2}  + 64(0) + 17 \\</h3>

We have the final answer as

<h3>(g \: \circ \: f)(0) = 17</h3>

Hope this helps you

If a package of corn chips weighs 1.2 ounces what is the weight in ounces of 48 packages ?
Naya [18.7K]
I'm not usually good at these questions but you can get a calculator that does weight multiplied by units.
so with your question it would be :

1.2 ounces x (48 units)
=  57.6 ounces




57.6 ounces
