Mathematics
1 answer:
Pachacha [2.7K]2 years ago
6 0

Answer:

160 units.

Step-by-step explanation:

In order to find the minimum cost, we need to find the vertex of the equation since it is the lowest point of the graph. To find the vertex, we use the following equation.

x = -b/2a

In this equation, a is the coefficient of x^2 and b is the coefficient of x. So we plug in and solve.

x = -b/2a

x = -(-80)/2(.25)

x = 80/.5

x = 160

What value of k makes the statement true?<br> x² (2x³ + 7x²yª) = 2xªyª + 7x³y8?
Nina [5.8K]

By apply the distributive property of multiplication, the value of k which makes the statement true is 1.

<h3>What is the distribution property?</h3>

Mathematically, the distributive property of multiplication is given by tis expression:

x(y + z) = xy + xz.

Next, we would apply the distributive property of multiplication to the given equation by distributing to the left-hand side using xy⁴:

k(2x⁴y⁴ + 7x³y⁸) = 2x⁴y⁴ + 7x³y⁸

Dividing both sides by the common factor, we have:

k = (2x⁴y⁴ + 7x³y⁸)/(2x⁴y⁴ + 7x³y⁸)

k = 1.

In conclusion, the value of k which makes the statement true is 1.

Find the possible values of k if one of the roots of the quadratic equation x^2 - kx + 8 = 0 is twice the other.​
kondor19780726 [428]

Answer:

k=\pm 6

Step-by-step explanation:

The given quadratic equation is :

x^2 - kx + 8 = 0

One of the roots of this equation is twice that of the other. Let the roots are \alpha \ and\ \beta, \alpha =2\beta

Sum of roots, \alpha +\beta =\dfrac{-b}{a}

\alpha +\beta =\dfrac{-(-k)}{1}\\\\\alpha +\beta =k\\\\3\beta =k\ .......(1)

Product of roots,

\alpha \beta =\dfrac{c}{a}\\\\2\beta ^2=\dfrac{8}{1}\\\\\beta =\pm 2

If \beta =\pm2,

k=3(2)\\\\=\pm 6

So, the value of k is equal to \pm 6.
