Answer:

Step-by-step explanation:

There are 144 cubes in total.

In the first layer are 9x4=36 cubes

So 144÷36= 4 layers this is the answer.

The discriminant of the function is 120, and the function has 2 different x-intercepts

<h3>How to determine the discriminant?</h3>

The function is given as:

f(x) = -7x^2 + 8x + 2

The discriminant (d) is calculated using:

D =b^2 - 4ac

So, we have:

D = 8^2 - 4 * (-7) * 2

Evaluate

D = 120

Because the value of D is greater than 0, then the function has 2 different x-intercepts

Let a and b be rational numbers. Then by definition

ohaa [14]

Answer:

The product of two rational numbers is a rational number

Step-by-step explanation:

I'll quickly recap the proof: a rational number is, by definition, the ratio between two integers. So, there exists four integers m,n,p,q such that

$a=\dfrac{m}{n},\quad b=\dfrac{p}{q}$

If we multiply the fractions, we have

$ab = \dfrac{mp}{nq}$

Now, mp and nq are multiplication of integers, and thus they are integers themselves. So, ab is also a ratio between integer, and thus rational.

What is in extraneous solution to the equation b/b-7 - 2/b = 7/ b-7 ?

alexandr402 [8]

Answer:

b = 2 or b = 7

Step-by-step explanation:

b/(b-7) - 2/b = 7/ (b-7)

b * b - 2(b - 7) = 7 * b

b^2 - 2b + 14 = 7b

b^2 - 9b + 14 = 0

(b - 2)(b - 7) = 0

b - 2 = 0; b = 2

b - 7 = 0; b = 7

Answer

b = 2 or b = 7

What can be said about the discriminant of the graph below?

san4es73 [151]

Answer:

C. The discriminant is negative, so there are no solutions.

Step-by-step explanation:

We see that the given figure is a graph of a parabola.

The equation of the given parabola is $y=(x-3)^{2}+1$ .

Simplifying the equation in quadratic form, we get,

The equation is $y=(x-3)^{2}+1$ i.e. $y=x^{2}+9-6x+1$ i.e. $y=x^{2}-6x+10$ .

We know that the discriminant of a quadratic equation $ax^{2}+bx+c=0$ is given by $D=b^{2}-4ac$

So, from the equation $x^{2}-6x+10=0$ , we have,

a = 1, b = -6 and c = 10

Thus, the discriminant is $D=(-6)^{2}-4\times 1\times 10$

i.e. $D=36-40$

i.e. $D=-4$

So, the discriminant is -4 i.e. negative.

Hence, as the discriminant is negative, there are no solutions.
